Back

Replication.

Front

What are the possible gametes from a parent with genotype AaBb?

Back

AB, Ab, aB, ab.

Front

Which type of mutation is most likely to cause a significant change in the protein produced?

Back

Frameshift mutation.

Front

In which phase of the cell cycle does DNA replication occur?

Back

S phase.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for translation.

Front

What is a point mutation?

Back

A change in a single nucleotide in the DNA sequence.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of copying DNA to RNA; translation is the process of synthesizing proteins from mRNA.

Front

What is a frameshift mutation?

Back

A mutation that results from the insertion or deletion of nucleotides, altering the reading frame of the gene.
