DNA Replication and Transcription

Front

What enzyme does transcription use?

Back

RNA polymerase

Front

What is the term for a three-nucleotide sequence that codes for an amino acid?

Back

Codon

Front

Guanine bonds with which nucleotide?

Back

Cytosine

Front

What property of tRNA allows it to assist in protein assembly at ribosomes?

Back

Each of many tRNA molecules contains an anticodon, and it binds to a specific amino acid.

Front

What are short DNA fragments that are attached to the primer and make up the lagging strand?

Back

Okazaki fragments

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of helicase during DNA replication?

Back

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

Front

What is the difference between leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short fragments.

Front

What is the significance of the promoter region in transcription?

Back

The promoter region is a sequence of DNA that initiates transcription by providing a binding site for RNA polymerase.

Front

What is the process by which mRNA is synthesized from a DNA template?

Back

Transcription.
