Answer:

Change occur in the genetic makeup.

Explanation:

Brian means that the change occur in the genetic makeup of the mitochondrial DNA that change the structure as well as the function ability of mitochondria which is responsible for the generation of energy for the cell. The mitochondrial DNA are passed from mother to offspring through the egg cell. He signify mitochondrial DNA because the change occur only in the mitochondrial DNA not in the whole organism's DNA.

Brian indicates that the mutation is in a gene found in mitochondrial DNA. What Brian means by this is that mitochondria contain a single circular chromosome that encodes 13 proteins, and that may be due to abnormalities of mitochondrial DNA, to understand better we need.......

Each cell has several hundred mitochondria in its cytoplasm. Mitochondria contain a single circular chromosome that encodes 13 proteins, several ribonucleic acids (RNA, ribonucleic acid) and several regulatory enzymes. However, > 90% of mitochondrial proteins are encoded by nuclear genes. For practical purposes, it is assumed that all mitochondria are inherited from the cytoplasm of the egg, so mitochondrial DNA comes only from the mother.

Mitochondrial diseases can result from abnormalities of mitochondrial DNA or nuclear DNA (eg, deletions, duplications, mutations). Tissues with high energy production (eg, muscle, heart, and brain) are at particular risk of dysfunction due to mitochondrial abnormalities. Specific abnormalities in mitochondrial DNA result in characteristic manifestations. Mitochondrial diseases are equally common in men and women.

With this information, we can say that mitochondria have DNA and can undergo mutations, which can cause abnormalities in this DNA.

Answer:

This question lacks options, the options are:

A. All 270 tall plants were heterozygous

B. All 270 tall plants were homzygous.

C. Only 90 plants were homzygous.

D. All dwarf plants were homzygous.

The answer is D.

Explanation:

This question involves a single gene coding for height in pea plants. The allele for tallness (T) is dominant over that of dwarfness (t). This means that a dwarf plant can only be homzygous recessive (tt) while a tall plant can either be homzygous (TT) or heterozygous (Tt).

According to the question, two tall heterozygous pea plants were crossed i.e. Tt × Tt. Based on this cross, a phenotypic ratio of 3:1 is expected, which is in accordance with the 270 tall plants and 90 dwarf plants (360 total) that was obtained in the cross. Since dwarfism in pea plants is a recessive trait, this means that all the dwarf plants produced in this cross (90) were homzygous (tt).

The expected genotype resulting from the cross was that all dwarf plants were purebreed.

So, according to the given information, there is a cross between Tt × Tt.  A phenotypic ratio of 3:1 is desired, which is in accord with the 270 tall plants and 90 dwarf plants (360 total) that were got in the cross.

Since dwarfism in pea plants is a different feature, this means that all the dwarf plants produced in this cross (90) were (tt).

Answer:

The keratin-producing cells known as keratinocytes are the primary type of cells found in the epidermis. They originate from the stratum basale's stem cells. They act as a barrier from harmful environmental elements like pathogens and ultraviolet radiation. Dermatophytes are a group of physiologically and morphologically associated molds, which release an enzyme keratinase.

Keratinases are the serine proteases that destroy the keratin found in skin, nails, and hair.

The dermatophytes lead to infections of the hair, skin, and nails, as they obtain nutrients from the keratinized substances. These pathogenic fungi are most actively found in the external cornified layers of the cells of dead skin were they less likely to get determined and eliminated by the active dendritic cells.

Answer:

The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds

Explanation:

The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.

Explanation:

its a simple question and I'm pretty sure you made a typo oh well

Answer:

Calcium is an essential ion as it required in the contraction of both cardiac and skeletal muscles. The sarcoplasmic reticulum stores these ions that are pumped by calcium pumps and released when contraction and functioning of these muscles. It binds to troponin and altered the change of shape and prevents tropomyosin from the site of the binding.

In case of cardiac muscle, the coupling Ca2+ is from its contact with extracellular concentration of Ca2+. When the calcium is released in the skeletal muscle it leads to the interaction between the actin and myosin. The binding sites of the myosin is exposed that bind and forms cross bridges with actin and hence helps in the contraction of the muscle. With the calcium induced calcium release, it helps in the contraction of the cardiac muscle. As the calcium is released it leads to initiation of the smooth muscle contraction in the cardiac muscle through binding of calmodulin and leads to activation of the myosin light chain kinase enzyme. There are receptors for the Calcium induced calcium release within the cardiac cells called as cardiomyocyte that binds to the calcium during depolarization and hence releases more calcium ions within the cells.

Answer and Explanation:

Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.

Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.

Answer:

Complementation.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.

Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.

Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.

In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.

Hence, the above breeding is an example of complementation.

Answer:

I think b is the correct answer of the question

Answer:

Within the mitochondria, the import takes place post-translationally. The imported protein must be in an unfolded condition so that it can go through the mitochondria's import machinery. In the existence of methotrexate, the bound DHFR moiety remains in the folded state, and thus, stays on the surface of mitochondria.

It is witnessed that the presequence must be of the length of 55 amino acids to cover both the membranes of mitochondria and must be of about sixty amino acids length to associate with the mhsp70. If the presequence of this methotrexate bound DHFR is of seventy-five amino acids in length, it can associate with mhsp70 within the matrix, to initiate the ATP reliant import within the mitochondria. Due to the presence of various endocytic and intracellular sorting signals, multiple adaptors are essential.

Answer:

3m/s²

Explanation:

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

According to this question, a car is said to accelerate from 4 m/s to 16m/s in 4 seconds. This means that;

v = 16m/s

u = 4m/s

t = 4s

a = 16 - 4/4

a = 12/4

a = 3m/s²
