Protein Synthesis and Mutations Review

Front

What is a chromosomal deletion?

Back

A chromosomal deletion is a mutation where a segment of the chromosome is lost or removed.

Front

What is chromosomal duplication?

Back

Chromosomal duplication is a mutation where a segment of a chromosome is copied and remains within the chromosome.

Front

Are all mutations harmful?

Back

No, not all mutations are harmful; some can be beneficial or neutral.

Front

What causes a frameshift mutation?

Back

Frameshift mutations are caused by insertions or deletions of nucleotides in the DNA sequence.

Front

What RNA bases pair with TACGAA during transcription?

Back

AUGCUU pairs with TACGAA during transcription.

Front

What is translocation in genetics?

Back

Translocation is a chromosomal mutation where a segment of one chromosome breaks off and attaches to another chromosome.

Front

What is inversion in genetics?

Back

Inversion is a chromosomal mutation where a segment of a chromosome is reversed end to end.

Front

Define mutation.

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotides to the DNA sequence, while deletion mutations remove nucleotides.
