VCS Biology_ Unit 4_ RNA, Protein Synthesis & Mutations

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) binds to a specific amino acid and transports it to the ribosome, where proteins are synthesized.

Front

What is the start codon in mRNA?

Back

The start codon is AUG, which codes for the amino acid Methionine.

Front

What is the process of transcription?

Back

Transcription is the process by which DNA is copied into mRNA.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.

Front

What are insertion mutations?

Back

Insertion mutations occur when one or more nucleotides are added to the DNA sequence.

Front

What are deletion mutations?

Back

Deletion mutations occur when one or more nucleotides are removed from the DNA sequence.

Front

Why are mutations significant in biology?

Back

Mutations can lead to genetic diversity, but they can also cause diseases or malfunctions in proteins.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.
