B. drip irrigation because it will water the plants with less water
Answer:
A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.
Explanation:
In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.
But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which less transcription will occur.
Answer: disconformities
Explanation: disconformities are usually erosional contacts that are parallel to the bedding planes of the upper and lower units. I hope this helps
Answer:
No,
Although the atmosphere is mostly made up of nitrogen, it is in the form of gas known as dinitogen N2. Plant cannot use this form.
Explanation:
Answer:
it is the third option: DNA reads the nucleotide sequences found in genes. Genes are located on tightly wound structures called chromosomes.
