Yes this statement is true
The process of turning off and on of genes is known as gene regulation.
Explanation:
When the gene is turned on, it instructs the cells to construct a particular protein. The proteins are the molecules that build your body with collagen, tendons, and bones or keratin in your hair.
The gene regulatory proteins allow the individual genes of an organism to be turned on or off . in different cell types there are different selections of gene regulatory proteins. The patterns of the gene expression gives each cell its unique characteristics.
Each cell produces or turns on only a fraction of its genes. the remaining genes are repressed or turned off. this process is known as gene regulation. The signals from the environment or from other cells activate proteins called transcription factors.
Answer:
C
Explanation:
During their development, many organisms look similar, suggesting that very different organisms may have a common ancestor. - Think of the human fetal neural / spine development which mirrors other species.
Increases genetic variation, which in and of itself has extreme benefits such as protection against disease, capability to evolve, etc
