The correct increasing order of size for the cell components responsible for heredity is
Answer Details
Heredity is the passing of traits from parents to their offspring, and it involves the transmission of genetic information from one generation to the next. The components responsible for heredity are the ones that carry and transfer the genetic information from parent to offspring.
DNA is the molecule that carries the genetic information in all living organisms, and it is organized into structures called chromosomes. A gene is a segment of DNA that codes for a specific trait, and it is located on a chromosome. The nucleus is the part of the cell that contains the chromosomes.
Therefore, the correct increasing order of size for the cell components responsible for heredity is DNA → gene → chromosome → nucleus.
