A scientist performs an experiment that uses a chemical inhibitor to inhibit a kinase enzyme in a signaling pathway and this res

ults in a decrease in signaling. If the scientist wanted to be sure that this kinase was indeed responsible for the decrease in signaling, which of the following would be the best to use?A. Use of luciferaseB. Use of antibodiesC. Use of another inhibitor that targets a unrelated kinase.D. Use of siRNA to the kinase mRNA in question.E. None of the above

Answer:

The correct answer is option D. "Use of siRNA to the kinase mRNA in question".

Explanation:

Small interfering RNA (siRNA), also known as interfering or silencing RNA, is a small molecule of RNA (20-25 base pairs) that binds to a particular region of a messenger RNA, avoiding its translation into protein. These type of interfering molecules are often used to silence genes and corroborate their function by analyzing what are the biological consequences of avoiding their translation into protein. Therefore, if a scientist wants to know if a kinase is indeed responsible for the decrease in signaling, a good option is to use a siRNA to the kinase mRNA in question.

mixer [17]

Answer:  D) constructive process

Explanation:

Deposition is the geological <u>process</u> in which sediments, soil and rocks are <u>added</u> to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, <u>building up</u> layers of sediment.

What similarities and differences do you see between the bacteria and the human cells? Are these cells prokaryotes or eukaryotes
Ainat [17]

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

DNA sometimes has chemical groups attached, called methyl groups, that affect gene expression. Suppose that, during each hour, f
ira [324]

Answer:

f = m - u

Explanation:

DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).

In consequence, the equation is

f = m - u

STatiana [176]

Answer:

The correct answer is - The cranial nerves and the spinal nerves.

Explanation:

The central nervous system or CNS includes the brain and the spinal cord of the nervous system where it takes sensory information, integrates, and responds accordingly. The spinal cord acts as a conduit for signals between the brain and the rest of the body.

Spinal nerves and crania; both play an essential role in taking sensory information and respond accordingly. Spinal nerves are nerves that help in sending motor, sensory, and autonomic signals between the CNS and the body. The cranial nerves supply information to the CNS and then from the CNS to the body.

Thus, the correct answer is - The cranial nerves and the spinal nerves.
