Unit 5: Genetics Summative Review

Front

Where does transcription take place in the cell?

Back

Transcription takes place in the nucleus of the cell.

Front

Where does translation take place in the cell?

Back

Translation takes place in the ribosome.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide is made up of a phosphate group, deoxyribose sugar, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

Front

What is the role of mRNA during translation?

Back

mRNA codes for specific amino acids and provides the sequence for protein synthesis.

Front

What signals the ribosome to stop translation?

Back

The mRNA sequence codes for a stop codon, such as UGA.

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet within mRNA that signals the end of translation.

Front

What is the significance of the term 'semi-conservative' in DNA replication?

Back

In semi-conservative replication, each new DNA molecule consists of one old strand and one newly synthesized strand.

Front

What is the function of DNA helicase?

Back

DNA helicase unwinds the DNA double helix during replication.

Front

What is the first amino acid coded by the mRNA sequence AUG?

Back

The first amino acid coded by the mRNA sequence AUG is Methionine.

Front

What is the sequence of amino acids produced from the mRNA segment AUG CUA GUG AAA?

Back

The sequence of amino acids is Methionine-Leucine-Valine-Lysine.
