How are genes organized in DNA?

Answers

Answer 1

Typically, the genes are organized in DNA in the form of chromosomes. Chromosomes are structures that resemble threads and are found inside the nucleus of plant and animal cells.

A gene is the fundamental physical and useful unit of heredity. DNA is what makes up genes. Some genes serve as instructions for making proteins, which are molecules. However, a lot of genes don't make proteins.

Genes are found on these chromosomes. Protein and a single molecule of deoxyribonucleic acid (DNA) make up each chromosome. DNA contains the specific instructions that give each living thing its individuality and are passed down from parents to children. Chromosomes, which are made up of long strands of DNA, contain many genes. Each gene has its own locus (plural locus) on the chromosome, and each chromosome has its own sequence of genes.

Multiple sequence alignment is a method that can be used to compare three or more biological sequences to determine homology and evolutionary relationships between species. This is done by selecting a target protein or DNA sequence (consensus) and comparing it across other species’ sequences. Conservation is a statistical analysis that describes how much the target sequence is observed across the selected group of species. A higher conservation score indicates that the protein or gene is more ancient or more critical across species.

Explanation:

Prozac, Zoloft, and Paxil are called SSRIs because they a decrease the release of oxytocin in the endocrine system in anxiety disorders. b slow the normal reuptake of excess serotonin from synapses in depression. c successfully level the emotional highs and lows of bipolar disorder. d stimulate the release of norepinephrine into the bloodstream in depression. e increase the number of receptor sites for dopamine in schizophrenia.

Answers

Answer:

b slow the normal reuptake of excess serotonin from synapses in depression

Explanation:

Serotonin is a neurotransmitter that transports signals or messages between neurons.

Although other neurotransmitters are involved in depression affection, alteration in serotonin levels is an important cause of the disease.

Affected people that express depression show an alteration of the normal serotonin levels in the interneuronal space. There is a noticeable decrease in molecule concentration due to an increase in its reuptake.

The substances used in the depression treatment belong to the SSRI group. SSRI means Serotonin Selective Recapture Inhibitor. It means that these substances inhibit the reuptake of serotonin that usually occurs in affected patients.

ISSR treats depression by enhancing serotonin levels and its transmission by blocking the reuptake in neurons. In this way, there is more serotonin available to improve communication between neurons.

ISSRs are selective because their principal target is the serotonin molecule and not the other neurotransmitters.

Use two examples for plants to explain how the development of new technologies such as radioisotopes has increased our knowlegde of reactions in plants.​

Answers

Answer: The radioactive isotopes can be used to track many physiological functions and chemical reactions occurring within the cells of the living organisms including plants.

Explanation:

Phosphorus uptake by the plants: Phosphorus is an essential mineral required by the plants for their growth and metabolism. The radioactive phosphorus-32 can be used to track back the rate at which the plant absorbs the phosphorus from the soil. This can help scientists to identify plants that can absorb phosphorus more quickly.

Pesticides levels in the plants: The pesticides levels in the plants can be traced by using radioisotopes such as chlorine-36. This can be used to trace the fact that how much of pesticide is present in the soil and how much of it is utilized by the plants. This is helpful identifying the fact that which pesticide is useful for the growth of the plants.

Which component of RNA
replication has a structure similar to that of remdesivir?

Answers

Answer:

RNA nucleotide.

Explanation:

RNA nucleotide is the part of RNA replication that has similar structure to Remdesivir. Remdesivir is covalently bonded to the replicating RNA, which blocks further synthesis of RNA. This Remdesivir work against the viral polymerase and prevents viral spreading by blocking the synthesis of RNA. Remdesivir has similar structure to RNA nucleotide but different in their functions. Remdesivir is used against many viral infections due to its effectiveness on the RNA replication.

A scientist wanted to formulate a pill to attack a specific type of bacteria that infects the throat. Which biological component would be best to use as a model for the pill’s function?
bacteriocytes
phagocytes
complement system
antibodies

Answers

Answer:

thx but the answer is D

Explanation:

A pill formulated to attack a specific type of bacteria that infects the throat would best follow the operations of antibodies.

What are antibodies?

Antibodies are chemicals produced by the immune system of the body in response to external attacks by foreign substances.

In other words, antibodies are like weapons deployed to defend the body from external attacks.

A pill designed to attack a specific type of bacteria that infects the throat will be most effective if it follows the operations of antibodies.

Since different antibodies are produced for different external invasions, the pill will also be most effective by being specific in its actions.

Answers

Answer:

C: elements like carbon, nitrogen, and phosphorus

Explanation:

Choice C is the correct answer.

Decomposers leave elements like carbon, nitrogen, and phosphorus behind after getting their energy. Therefore, option C is correct.

What are decomposers?

Decomposers are creatures that transform dead plants and animals into humus, a material with a deep brown color. Any ecosystem needs decomposers to function properly. Plants won't obtain vital nutrients if they aren't present in the ecosystem, and they will accumulate decaying objects.

Each contributes to the food recycling process in a different way. To transform dead plants or animals into simple substances, fungi release compounds. Some of these elements are absorbed by them for growth, while others go into the soil. As they ingest dirt, earthworms break down decaying plant and animal debris.

They leave elements such as carbon, nitrogen, and phosphorus after the decomposition of matter. Therefore, option C is correct.

Answer the lab question, "What is the effect of the
inheritance of one trait on the inheritance of a
second trait?" with a hypothesis. Remember that
you can either assume that the two genes are
independent or that they are linked. What results
would you expect in either case?
Hypothesis:
DONE

Answers

Answer:

Hypothesis: An inherited characteristic is not able to interfere in the inheritance of another characteristic in the same organism.

Explanation:

An inherited feature does not interfere with another inherited feature. This is because the genes are inherited by joining the gametes, which contain the genes of the organism's parents. Each gene is distributed in gametes completely randomly and independently. Inheritable characteristics are represented by these genes. In this way, genes are inherited independently, they do not interfere with inheritable characteristics. However, in genes inherited together, we can consider that only one inheritable trait would be presented, since these genes would interfere in the construction of another trait. This can be studied through hybrid crossings in living beings.
