Question

Which of the following characterizes DNA: A.Non.coding sequences that get deleted in the course of evolution B.Coding sequences that regulate gene expression C.Non-coding sequences that are expressed in different cell types

Answer 1

Coding sequences that regulate gene expression

Answer 2

The correct answer will be option-B.

Step-by-step explanation:

DNA is a molecule which acts as the genetic material of the cell. A living cell passes this genetic material to the daughter cell as it stores the information required by the cell.

The long DNA strand contains both coding and non-coding sequence in its length. Since the coding sequence of a DNA is known as "gene" which codes for a trait of an organism as well as it controls the expression of other genes to express a particular trait.

Thus, Option-B is the correct answer.
