Unit 5 Practice Test Review (CopyMC)

Front

What enzyme is responsible for adding nucleotide bases to create a new DNA strand from an original DNA strand?

Back

DNA Polymerase

Front

Which molecule serves as a copy of a gene sequence from DNA?

Back

mRNA (messenger RNA)

Front

What is the complementary DNA sequence for TTTGGGCCCAAA?

Back

AAACCCGGGTTT

Front

What type of mutation occurs when a nucleotide base is added to a DNA sequence?

Back

Insertion

Front

What is the amino acid sequence for the mRNA strand UGG-ACU-CGA-GUG?

Back

Trp-Thr-Arg-Val

Front

What is the role of RNA Polymerase in the cell?

Back

RNA Polymerase synthesizes RNA from a DNA template during transcription.

Front

What is the function of Helicase in DNA replication?

Back

Helicase unwinds the DNA double helix, separating the two strands.

Front

Define the term 'mutation' in the context of genetics.

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.
