te it.
1) What two substances make the backbone of the DNA molecule?

2) Are the backbones of the DNA molecule identical in all living things?

3) Are the base pairs always the same?

4) If there were five guanine bases in one strand of your model of DNA, how many cytosine bases would there be in the complementary strand?

5) If there were 10 bases of thymine in one strand of your model of DNA, how many adenine bases would there be in the complementary strand?

6) If the DNA molecule is so similar among all living things (the pairings are always the same and that there are only six components that make up DNA), why is there so much diversity of life?

DNA regions that are transcriptionally silenced by hypercondensation have often undergone a modification of their _______ residu
inessss [21]

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.

What is the approximate percentage of guanine in the DNA genome of E. coli?
Nadya [2.5K]

Answer:

25%

Explanation:

<em>The approximate proportion of G + C content in the genome of E. coli has been reported to be 50%. According to Chargaff's rule, the amount of guanine in any DNA must be approximately equal to the amount of cytosine. </em>Hence,

if G + C = 50 and G = C,

then

G = C = 25

Therefore, the approximate percentage of guanine in the genome of <em>E. coli </em>would be 25.
