1. Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide. This produces an alternating backbone of sugar - phosphate - sugar - phosphate all along the polynucleotide chain.

2. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.

3. Enzymes that participate in the eukaryotic DNA replication process include: DNA helicase - unwinds and separates double stranded DNA as it moves along the DNA. It forms the replication fork by breaking hydrogen bonds between nucleotide pairs in DNA. DNA primase - a type of RNA polymerase that generates RNA primers.

4. Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

5. RNA plays a central role in turning genetic information into your body's proteins. This remarkable molecule also carries the genetic instructions for many viruses, and it may have helped life get its start.

6. the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.

7. Of the many types of RNA, the three most well-known and most commonly studied are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), which are present in all organisms.

8. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template.

9. A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids.

10. Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.

11. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein.

12. A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

13. A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

14. There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu -----> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.

15. By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.

16. Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body. Cancer is the second-leading cause of death in the world.

why blood flow in a leg vein is slow when there is lack of movement?​

Answers

Answer:

Lack of movement allows blood to circulate in a vein very slowly by sitting still for long periods of time. Slow-flowing blood is more likely to clot than normal-flowing blood. This issue is referred to as deep vein thrombosis (DVT). In DVT, as seen in the diagram, the clot normally takes place in a leg vein.

Explanation:

Lack of movement by still for long periods of time makes blood flow very slowly in a vein it is because the blood that flows slowly is more likely to clot than blood that flows normally.

What are the veins called in the leg?

Large leg veins are saphenous veins. The leg veins that become weak in the most people age are the superficial veins and perforator veins.

The superficial and undesirable visible branches are known as varicose, reticular, and spider veins.

When sitting still, the flow of blood flow becomes slow, it is caused because the blood that flows slowly is more likely to clot than blood that flows normally.

This condition is called deep vein thrombosis.

Thus, due to this condition, blood flow in a leg vein is slow when there is lack of movement.

Someone please help I took the picture this is my last question on my homework

Answers

Answer:

According to the image that represents a cell in the human body, the true statement is that structure 4 is the cell membrane that provides exchange of O₂ & CO₂.

Explanation:

In cells, the cell membrane acts as a semi-permeable barrier to the passage of substances, including nutrients and oxygen (O₂).

One of the functions of the cell membrane is to allow the exchange of O₂ —necessary for the cell— and carbon dioxide (CO₂), a product of cell metabolism that must be removed.

In the image, the structure identified with the number 4 corresponds to a cell membrane of human cells that provides this gas exchange.

The other options are not correct because:

Structure 1 is a ribosome, not a chloroplast. Structure 2 is the nucleus, not a vacuole containing DNA. Structure 3 is a mitochondria, but protein synthesis does not occur there.

Answers

Answer:

inside the cell to outside the cell.

Explanation:

Ape-x

Facilitated diffusion is the type of transportation that moves the ions and the molecules. The molecules are transported directly through the membrane from inside to outside. Thus, option B is correct.

What is facilitated diffusion?

Facilitated diffusion is the transportation of the molecules and ions across the cell membrane along the concentration gradient. It is a passive transport that involves the movement down the gradient.

The molecules are transported by the membrane proteins that facilitate their movement from inside of the cell towards the outer space of the cell. Unlike simple diffusion, facilitated diffusion uses energy in the form of ATP.

Therefore, the molecules present inside the cells will move directly towards the outside of the cell.

a strand of dna contains 10% adenine. what percentage of cytosine must be present in this strand of dna then?

a) 80%
b) 40%
c) 10%
d) 20%

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ 40 \% \ cytosine}}[/tex]

Explanation:

First, recall the base pairs in DNA:

Adenine and Thymine Cytosine and Guanine

We know this strand of DNA has 10% adenine. Since A and T pair, there must also be 10% guanine.

So, A and T make up 20% of the DNA strand.

That leaves 80% for cytosine and guanine. They are pairs, so they share this percentage equally.

80/2 =40

There must be 40% cytosine and 40% guanine.

The strand of DNA has 40% cytosine
