Question

Which statement is true?

There are a number of chromosomes on a given gene; all of these actively code for proteins.

Chromosomes contain many genes; not all genes are actively coding.

DNA contains a number of segments that code for specific proteins; these segments are proteins.

The segments of genes found on chromosomes are made of RNA, which codes for protein synthesis.

Answer 1

Chromosomes contain many genes; not all genes are actively coding.

Step-by-step explanation:

All cells in a given organism at a given time in their life contain the same code or genetic information as that first cell from which they originated, but not all genes are functioning in all cells at the same time and to the same degree. From this we can conclude that chromosomes contain many genes; Not all genes are actively coding.

In man, for example, there are genes that are actively coding only at a particular stage of life. Others in a particular organ. And still others only when a disease is underway.
