Please help and explain. Thank you!!!
Explanation / Answer
20) the correct option is option (d) the share size of X is more that Y as men have XY and females have XX hence females undergo dosage compansation where one X in female is inactive so to give the balance between the male and female chromosome expression .!!
21) the correct option is option (a) true yes the mRNA should have one stop codon to terminate translation and protein synthesis at a certain moment of time otherwise it will lead to addition of more amino acids leading to the change in function and properties of the amino acids hence can't work properly..!!
