Protein Synthesis

Front

What is protein synthesis?

Back

The process by which cells generate new proteins, involving transcription of DNA to RNA and translation of RNA to protein.

Front

What is a codon?

Back

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

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA, specifically mRNA, which occurs in the nucleus.

Front

What is translation?

Back

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

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What is the significance of the stop codon?

Back

Stop codons signal the termination of translation, indicating that the protein synthesis is complete.

Front

What is the central dogma of molecular biology?

Back

The central dogma describes the flow of genetic information: DNA -> RNA -> Protein.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic blueprint that dictates the sequence of amino acids in a protein.
