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

The correct answer will be option-B.

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.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
