Protein Synthesis

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) is responsible for copying the DNA and bringing the genetic information out of the nucleus to the ribosomes for protein synthesis.

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 function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) delivers amino acids to the ribosome during translation, helping to assemble the protein according to the sequence specified by the mRNA.

Front

Where does translation occur in the cell?

Back

Translation occurs in the cytoplasm, specifically at the ribosomes.

Front

In RNA, which base pairs with adenine?

Back

In RNA, uracil pairs with adenine.

Front

What is transcription?

Back

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

Front

What is the role of rRNA in protein synthesis?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in the assembly of amino acids into proteins during translation.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, and 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 corresponds to a specific amino acid or stop signal during protein synthesis.

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.
