DNA Helicase

Front

What does the complementary strand of the DNA sequence GCA AAG CTG C look like after replication?

Back

CGT TTC GAC G

Front

What is the result of transcribing the DNA sequence AAG CTG GGA into RNA?

Back

An mRNA strand with the sequence UUC GAC CCU.

Front

What amino acids result from the mRNA strand AUG CUG UGA?

Back

Methionine - Leucine - Stop

Front

What accurately describes the process of translation?

Back

Transfer RNA delivers specific amino acids to the ribosome, matching messenger RNA codons.

Front

What is the role of DNA Ligase in DNA replication?

Back

DNA Ligase joins Okazaki fragments on the lagging strand during DNA replication.

Front

What is the function of DNA Polymerase?

Back

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

Front

What is the process of transcription?

Back

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

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the significance of the start codon AUG?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for Methionine.
