Question

To be evolutionary successful, mutation must occur in :

• A. Germplasm DNA
• B. Somatoplasm DNA
• C. Plasma protein
• D. RNA

Answer 1

The correct option is A Germplasm DNA

• For a mutation to be evolutionary successful, it must occur in Germplasm DNA since germline mutations are the only one that can be passed on to offspring, when either a mutated sperm or oocyte come together to form a zygote.
  
• After this fertilization event occurs, germ cells divide rapidly to produce all of the cells in the body, causing this mutation to be present in every somatic and germline cell in the offspring; this is also known as a constitutional mutation.
  

So, the correct option is 'Germplasm DNA'.
