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.
Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.
Explanation:
Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.
The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.
Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.
In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.
