If a cells nucleus has 55% adenine bases, how many cytosine bases will be present?

Biology
1 answer:
Nostrana [21]3 years ago
8 0

If a cell’s nucleus has 55% adenine bases it also has 55% thymine bases, so the percentage of cytosine bases is 45% as same as  guanine bases.

This is known as Chargaff's rule which states that DNA should have a 1:1 ratio of pyrimidine and purine bases (the amount of guanine should be equal to cytosine and the same thing with adenine and thymine).

DNA molecule globally has percentage base pair equality: %A = %T and %G = %C.

An individual has a genetic disorder in which their cell is not forming the correct protein structure for the cell membrane to a
Andru [333]

Answer:

The type of regulation of gene expression that would have the greatest chance of success is Posttranslational control (E).

Explanation:

The defect is found on the structure of the protein, this means that the process of formation of the protein and the codons responsible for each amino acid in the protein is in correct order, this set the transcriptional and translational process aside as being correct.

Therefore, the problem lies in the formation of secondary or tertiary structure of the protein which requires a good number of proteins also, wherein lies tha main problem in the cell membrane protein. Thus the regulation of the posttranslational process and correction of the proteins needed at this stage will give the best chance of success.
