Gene Mutation Practice

Front

What is the role of ribosomes in protein synthesis?

Back

They synthesize proteins by linking amino acids.

Front

What type of mutation is represented by the change from ATTTGAGCC to ATTGAGCC?

Back

Deletion - Frameshift.

Front

What is a point mutation where one nucleotide base replaces an original nucleotide base?

Back

Substitution Mutation.

Front

What happens in a frameshift mutation?

Back

A nucleotide base is inserted or deleted, shifting the entire DNA sequence.

Front

What is the complementary DNA strand for TAAGCTACG?

Back

ATTCGATGC.

Front

Define a mutation.

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.

Front

What is a silent mutation?

Back

A mutation that does not change the amino acid sequence of a protein.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion adds one or more nucleotide bases, while deletion removes them.

Front

What is a chromosomal mutation?

Back

A mutation that involves a change in the structure or number of chromosomes.

Front

What is translocation in genetics?

Back

Translocation is the movement of a segment of DNA from one location to another within the genome.
