SOMEONE PLEASE CORRECT ME IF IM WRONG!
MN for this qs i think indirectly the qs is talking about mutation (base deletion) already and for the answer its looking for its effects. Meaning what happens after the mutation has occured which means the number of amino acids in the structure, also causes changes in the primary structure, active site has changed this also causes the enzyme to not function.
so yeah mentioning mutation won't give any marks as the qs is already asking tht

UAG is the mRNA triplet codon that causes a termination in protein synthesis.
The corresponding DNA triplet coding for this would be ATC.
They said the mutation would introduce thymine, which is T. So the arrow must point between an A and a C.
Answer is B

Easy!
Light splits water into oxygen and H+ and electrons!
The electrons are used to fill up the positively charged chlorophyll molecules of Photosystem II which are missing electrons.

On page 78 of the new syllabus, you'll find the list of all content removed from the syllabus.
One of them is:
[PA] describe the histology of the mammalian ovary and testis
So yes I think that question comes under this.
