Unit 4 Review

Front

What is the enzyme that builds mRNA during transcription?

Back

RNA Polymerase

Front

What is the term for a segment of DNA that codes for a single protein?

Back

Gene

Front

What is the consequence of not having a start codon (AUG) in protein synthesis?

Back

Protein synthesis wouldn't occur.

Front

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

Back

S phase

Front

Where does the start codon AUG enter during the initiation of translation?

Back

A (aminoacyl) site of the ribosome.

Front

What is the role of RNA Polymerase in transcription?

Back

It synthesizes mRNA from a DNA template.

Front

Define a gene in the context of genetics.

Back

A gene is a sequence of DNA that contains the information to produce a specific protein.

Front

What is the function of the start codon in translation?

Back

It signals the beginning of protein synthesis.

Front

What happens during the S phase of the cell cycle?

Back

DNA replication occurs, resulting in the duplication of chromosomes.

Front

What are the three main sites of a ribosome during translation?

Back

A (aminoacyl), P (peptidyl), and E (exit) sites.
