Protein Synthesis

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 acids.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 different amino acids that combine in various sequences to form proteins.

Front

What is a codon?

Back

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

Front

What is transcription?

Back

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

Front

What is translation?

Back

Translation is the process by which ribosomes read the sequence of mRNA and assemble amino acids into a polypeptide chain, forming a protein.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) is a type of RNA that transports specific amino acids to the ribosome during protein synthesis, matching them to the corresponding codons in mRNA.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, facilitating the translation of mRNA into a polypeptide chain.

Front

What is a peptide bond?

Back

A peptide bond is a covalent bond that links amino acids together in a protein, formed during the process of translation.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus of the cell, where DNA is located.
