Question

the dna sequence of a portion of gene in a wild type organism is TTACCATATTCACCC and the corresponding peptide sequence is leu-pro-tyr-ser-pro. The corresponding gene fragment in a phenotypic variant of the organism is TTCCATGTTCACCC and the peptide sequence is leu-pro-cys-ser-pro. This is an example of a(n) _______mutation (type) resulting in a _______mutation (effect).
A. Base substitution; silent B. Deletion; misses with C. Base substitution; misses when D. Insertion; nonsense E.

Explanation / Answer

Wildtype : TTA CCA TAT TCA CCC
Mutant : TT* CCA TAT TCA CCC

If you find those seqeunces, the A base in frist codon is absent in mutant gene, so, it is a type of deletion.

The answer is B. Deletion; misses with

Please conform the sequence of mutant gene TTCCATGTTCACCC. Is it a typo? Becuase in wildtype you mentioned it as TAT. Do conform...
