Protein Synthesis & Mutations

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence.

Front

What is the purpose of transcription in protein synthesis?

Back

Transcribing information in the DNA sequence for use by the cell.

Front

Which mutation will cause translation to stop?

Back

Mutation 1 only.

Front

What are the base-pairing rules in RNA?

Back

A-U and C-G.

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 is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where proteins are synthesized by translating mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine (T), while RNA is single-stranded and contains uracil (U) instead of thymine.

Front

What is a codon?

Back

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

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of protein synthesis.
