Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. They contain an amino group, a carboxyl group, and a unique side chain.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond that links amino acids together in a protein chain, formed through a dehydration reaction.

Front

What is protein synthesis?

Back

Protein synthesis is the process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acid sequences.

Front

What role does mRNA play in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into a polypeptide chain, effectively synthesizing proteins.

Front

What is the significance of a stop codon?

Back

A stop codon signals the termination of protein synthesis, indicating that the polypeptide chain is complete.

Front

What is the central dogma of molecular biology?

Back

The central dogma describes the flow of genetic information from DNA to RNA to protein, outlining the processes of transcription and translation.

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in translating that information into proteins.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA, which occurs in the nucleus of eukaryotic cells.
