3A and 3B CSA Review

Front

What is the role of weak hydrogen bonds in DNA?

Back

Weak hydrogen bonds hold the two strands of the DNA double helix together, allowing for the separation of strands during replication and transcription.

Front

What type of RNA brings the anticodon and amino acid to the ribosome?

Back

tRNA (transfer RNA) is responsible for bringing the anticodon and the corresponding amino acid to the ribosome during protein synthesis.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus of the cell.

Front

What are the three types of RNA?

Back

The three types of RNA are mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA).

Front

Which type of RNA is synthesized during transcription?

Back

messenger RNA (mRNA) is synthesized during transcription.

Front

What is the function of mRNA?

Back

mRNA carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is the function of tRNA?

Back

tRNA transports specific amino acids to the ribosome and matches them to the corresponding codon on the mRNA.

Front

What is the function of rRNA?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in protein synthesis.

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which then carries the genetic information to the ribosome.

Front

What is the significance of the anticodon in tRNA?

Back

The anticodon is a sequence of three nucleotides in tRNA that pairs with the corresponding codon on mRNA, ensuring the correct amino acid is added during protein synthesis.
