Question

What information can not be obtained from the sequence of a gene?A) Relationship between two species.B) Effects of a mutation on gene function.C) Whether the gene is methylated.D) Amino acid sequence of a gene.

Answer 1

Answer:

The correct answer is option C) "Whether the gene is methylated".

Explanation:

Gene methylation is a process at which methyl groups are added to fragments of DNA, which adds a charge to the sequence and usually repress the transcription process. It is not possible to predict whether the gene is methylated by looking at its sequence. Gene methylation is carried out by a family of enzymes called DNA methyltransferases (DNMTs), which can be specific or unspecific and often they act at the gene promoter section.
