Explanation / Answer

Ans.19- C codon is three nucleotide sequence that codes for specific amino acid or translational stop signal in a mRNA

Ans.20- C sickle cell disease E6V mutation results in change of a nagetively charged polar amino acid to a non polar amino acid as glutamine nagetively charged which is replaced by valine which is neutral making it non polar

Ans.21-A polymerisation of haemoglobin will couse sickling of RBC under low oxygen that will couse occlusion of microvasculer circulation leading to tissues ischaemia
