Unit 4 Review: Gene Expression & Mutations

Front

What is the location in the cell for transcription?

Back

Nucleus

Front

During transcription, this type of ribonucleic acid is responsible for copying the DNA and bringing it out of the nucleus.

Back

mRNA (messenger RNA)

Front

Identify the type of mutation: W - substitution, X - deletion, Y - insertion.

Back

W - substitution, X - deletion, Y - insertion

Front

What process is occurring when mRNA is synthesized from a DNA template?

Back

Transcription

Front

What process is responsible for translating mRNA into a protein?

Back

Translation

Front

What regulates gene expression for fur color in the arctic fox?

Back

Temperature

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.

Front

What are the three main types of mutations?

Back

Substitution, insertion, deletion.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during translation.

Front

What is the central dogma of molecular biology?

Back

DNA -> RNA -> Protein.
