Answer:
Yes.
Explanation:
Yes, both structural mutations and nondisjunction can play an important role in trisomy 21 which also called down syndrome. In this type of syndrome, extra copy of chromosomes is present in the cell. Down syndrome is a genetic disorder that causes various defects in the children such as learning problems, facial features, vision and hearing problems.

Answer:
(A) A transversion base substitution causing a missense mutation
(B) A transition base substitution causing a silent mutation
(C) A transversion base substitution causing a silent mutation
Explanation:
There are two types of base substitutions, transversions and transitions. A transition is when the a purine base is substituted with another purine base or a pyrimidine base is substituted with a pyrimidine base (e.g. Purines - A to G; G to A; Pyrimidines - C to T; T to C). A transversion occurs when a purine base is substituted with a pyrimidine base or a pyrimidine base is substituted with a purine base (e.g. A to T; C to A).
There are three main types of mutations, these are missense mutations, nonsense mutations and silent mutations. Missense mutations occur when a base is changed and the codon now codes for a different amino acid to before the mutation. Nonsense mutations occur when a base is changed and now the codon codes for a stop codon causing a premature stop of the translation process. Silent mutations occur when a base is changed but the new codon still codes for the same amino acid as before the mutation.
The answer is proteins.
The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life.
