Thre-Val-Glu-Leu-Iso

Front

What are mutagens?

Back

Chemicals or factors that cause mutations in DNA, such as UV radiation.

Front

Does the order of amino acids in a protein matter?

Back

Yes, the order determines the protein's structure and function.

Front

What is the role of RNA polymerase in protein synthesis?

Back

RNA polymerase synthesizes RNA from a DNA template during transcription.

Front

Define transcription in the context of protein synthesis.

Back

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

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 function of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine; RNA is single-stranded and contains uracil.
