5`-TGCGATCC-3`
is mutated to 5`-TGCGATGCC-3`
here the T is mutated to G, T is a pyrimidine and G is a purine, that is a pyrimidine is changed to purine.
Transition mutation: one purine is replaced with another purine, or a pyrimidine is replaced with another pyrimidine.
transversion: a purine is changed to pyrimidine and vice versa.
so this is a transversion mutation.
so the answer is transversion mutation.

Below are several DNA sequences that are mutated compared with the wild-type sequence: 3-TAC TGACTGACGAT C-5. Envision that each is a section of a DNA molecule that has separated in preparation for transcription, so you are only seeing the template strand. Construct the complementary DNA sequences (indicating 5' and 3' ends) for each mutated DNA sequence, then transcribe (indicating 5' and 3' ends) the template strands, and translate the mRNA molecules using the genetic code, recording the resulting amino acid...
A single mutation has occurred in the following DNA sequence. 5' ATG TTC CAG CCA 3' wild-type (normal) sequence 5' ATG TTC TAG CCA 3' mutant sequence a) Identify and classify the mutation according to its molecular structure (i.e., insertion, deletion base substitution (transversion), or base substitution (transition)). Briefly explain why you selected this classification. b) Identify and classify the mutation according to its functional effects (i.e., frameshift, missense, nonsense, or silent). Briefly explain why you selected this classification.
