monoallelic gene expression

Explanation:

<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>

A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.

When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.

If a cells nucleus has 55% adenine bases, how many cytosine bases will be present?
Nostrana [21]

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.
