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.

There are initially 1000 bacteria in a culture. The number of bacteria doubles each hour. The number of bacteria N present after
polet [3.4K]
There are several information's of immense importance already given in the question. Based on those information's the answer can be easily deduced. 
Initial number of bacteria in the culture = 1000
Number of bacteria after t hours = 1000 (2)^t
Then
1000 (2)^t = 50000
2 ^t = 50
t = 5.6

I hope the procedure is clear enough for you to understand.

Explain why plants along the road often die after the road is sprayed with a salt solution to melt ice
vovangra [49]

Explanation:

The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.
