Back

GTT

Front

What type of gene mutation has occurred here? T-G-A-C-C-A -> T-G-A-C-C-A-A

Back

Front

What type of gene mutation has occurred here? Normal-
AGA-TTC-ATA-GCG
Mutant-
AGA-TTC-AAT-AGC-G

Back

insertion frameshift

Front

DNA molecule segment is: TTACGCAAG
The mutated DNA segment is TTACGCAAC. This is an example of ___ mutation.

Back

Base Substitution

Front

A mutation that does NOT show up through protein function is called

Back

silent mutation

Front

A substitution mutation that has no effect on amino acids sequence

Back

Silent Mutation

Front

A nucleotide base is inserted or deleted shifting the entire DNA sequence. Entire protein will be changed.

Back

Frameshift Mutation

Front

Are all mutations bad?

Back

No

Front

Why are insertion and deletion mutations so harmful?

Back

They change all of the codons from the mutation on down the line, which changes the amino acid sequence.
