Answer:

b. methylation.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Hence, DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their cytosine residues termed methylation.

For example, CpG island methylation transcriptionally silences about 650 to 800 genes in patients suffering from colorectal cancer.

How is the cell structure related to its function in your body
Nastasia [14]

<span>A cell with a large surface area or with microvilli (which increase surface area) are specialized for absorption. Many cells have different protein markers on their surface to accept certain specific hormones and allow them into the cell, like muscle cells reacting to adrenaline. Muscle cells are long and able to contract, allowing for overall muscle contraction and body movement. </span>

<span>I guess the hormone part I mentioned applies to chemicals; endocrine cells produce hormones that other cells would not. </span>

<span>For organelles, muscle cells don't have many of the organelles that other cells do because of their very specialized functions. </span>

<span>I hope this helps, it would literally take volumes of text books to answer this question completely.</span>

andriy [413]

Answer:

The outside only looks pigmented because of the color reflecting off it, but the inside is white and unpigmented because it is reflecting all the colors. Does this help?
