DNA/RNA & Protein Synthesis Review

Front

What is a missense mutation?

Back

A missense mutation is a type of gene mutation where a base substitution changes the amino acid that should have been in the sequence.

Front

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

Back

DNA replication occurs during the S phase of the cell cycle.

Front

Where does transcription take place in a cell?

Back

Transcription takes place in the nucleus of the cell.

Front

What type of sugar is found in DNA nucleotides?

Back

The type of sugar found in DNA nucleotides is deoxyribose.

Front

Which enzyme is responsible for synthesizing RNA from a DNA template?

Back

RNA Polymerase is the enzyme responsible for making RNA from DNA.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is responsible for synthesizing new DNA strands during DNA replication.

Front

What is the function of helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands to allow replication.

Front

What is a silent mutation?

Back

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

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and is double-stranded, while RNA contains ribose sugar and is usually single-stranded.

Front

What is the central dogma of molecular biology?

Back

The central dogma of molecular biology describes the flow of genetic information from DNA to RNA to protein.
