protein synthesis

What is a codon?

• A sequence of three nucleotides on mRNA that specifies an amino acid.

• A type of protein that helps in DNA replication.

• A molecule that carries oxygen in the blood.

• A structure that forms the cell membrane.

What is the difference between prokaryotic and eukaryotic transcription?

• Prokaryotic transcription occurs in the cytoplasm, while eukaryotic transcription occurs in the nucleus.

• Both prokaryotic and eukaryotic transcription occur in the cytoplasm.

• Eukaryotic transcription occurs in the cytoplasm, while prokaryotic transcription occurs in the nucleus.

• Prokaryotic transcription occurs in the nucleus, while eukaryotic transcription occurs in the cytoplasm.

What is the process of converting mRNA into a protein called?

• Transcription

• Translation

• Replication

• Translocation

Which organelle is responsible for reading mRNA and synthesizing proteins?

• Mitochondrion

• Nucleus

• Ribosome

• Endoplasmic Reticulum

What is the role of the promoter in transcription?

• The promoter is a DNA sequence that signals the start of transcription.

• The promoter is a protein that binds to RNA polymerase.

• The promoter is a type of RNA that carries genetic information.

• The promoter is a sequence that terminates transcription.

What is the role of ribosomal RNA (rRNA) in protein synthesis?

• rRNA carries amino acids to the ribosome.

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

• rRNA is involved in the transcription of DNA.

• rRNA helps in the folding of proteins.

What is the process called where mRNA is synthesized from a DNA template?

• Translation

• Replication

• Transcription

• Translocation

True or False: tRNA contains anticodons that pair with codons on mRNA.

• True

• False

• Sometimes

• Only in certain organisms

What is an anticodon?

• A sequence of three nucleotides on tRNA that pairs with a corresponding codon on mRNA.

• A type of protein that helps in DNA replication.

• A segment of DNA that codes for a specific protein.

• A molecule that transports amino acids to the ribosome.

What is the function of messenger RNA (mRNA)?

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

• mRNA helps in the replication of DNA.

• mRNA is responsible for the transport of amino acids to the ribosome.

• mRNA acts as a catalyst in biochemical reactions.
