Protein Synthesis

Front

What happens to DNA during transcription?

Back

It unzips so mRNA can copy its template and then it zips back up.

Front

Which nitrogenous base is not found on RNA?

Back

Thymine.

Front

What is the set of 3 nitrogenous bases found on tRNA that is used to match base pairs with mRNA codons?

Back

Anticodon.

Front

What type of RNA brings the needed amino acid to the ribosome when its anti-codon matches the mRNA codon being read during translation?

Back

Transfer RNA or tRNA.

Front

During the elongation phase of transcription, what does RNA polymerase do?

Back

RNA polymerase bonds and transcribes DNA template onto mRNA by base pairing.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are the three main types of RNA involved in protein synthesis?

Back

Messenger RNA (mRNA), Transfer RNA (tRNA), and Ribosomal RNA (rRNA).

Front

What is a codon?

Back

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

Front

What is the function of ribosomal RNA (rRNA)?

Back

rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

How does tRNA recognize the correct amino acid to bring to the ribosome?

Back

tRNA has an anticodon that pairs with the corresponding codon on the mRNA.
