SB2a. Protein Synthesis

Front

What is the role of helicase in DNA replication?

Back

Helicase is the enzyme that unzips the DNA double helix, separating the two strands to allow replication to occur.

Front

What type of macromolecule is synthesized in ribosomes?

Back

Proteins are synthesized in ribosomes by following the instructions encoded in DNA.

Front

Where does DNA replication occur in a cell?

Back

DNA replication takes place in the nucleus of the cell.

Front

Where does transcription occur?

Back

Transcription occurs in the nucleus, where DNA is transcribed into messenger RNA (mRNA).

Front

What does each codon in messenger RNA code for?

Back

Each codon in messenger RNA codes for a specific amino acid.

Front

What is the function of messenger RNA (mRNA)?

Back

mRNA carries genetic information from the DNA in the nucleus to the ribosomes, where proteins are synthesized.

Front

What is the process of transcription?

Back

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

Front

What is the difference between DNA and RNA?

Back

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

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.
