Answer:
The correct answer will be option-formation of heterochromatin
Explanation:
Methylation of DNA is the epigenetic mechanism which controls the expression of a gene by adding a methyl group to the cytosine bases in eukaryotic DNA.
The methylation of DNA converts the cytosine residues to the 5-methylcytosine catalysed by DNA methyltransferase enzyme. This results in the silencing of the gene and transcription get switched off.
Studies have shown that DNA methylation is involved in the formation and maintenance of the heterochromatin structure which is the condensed form of the chromatin in which transcription is switched off.
Thus, the formation of heterochromatin is the correct answer.
Answer:
All of the following help the cell regulate gene expression during Step 2 of protein formation EXCEPT
specialty factors binding to the RNA polymerase, altering its specificity
Explanation:
<span>solid triglycerides are called fats and liquid triglycerides are called oils. The carboxylic acid moieties involved in forming fats and oils are often referred to as <span>fatty acids</span></span>
Answer:
B) plants get the energy they need for photosynthesis from sunlight
Explanation:
<span>Answer: c. release 50-80% of their water back into the ecosystem
Rainforest has a high rate of rain, which gives the plant abundant amount of water. There is no need for the plant to conserve and retain water. it doesn't need the ability to adapt to drought either.
Rainforest has a high precipitation because of the transpiration.
