6C transcription and translation

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information needed for protein synthesis.

Front

What is the product of transcription?

Back

The product of transcription is messenger RNA (mRNA).

Front

What is translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to assemble a chain of amino acids, forming a protein.

Front

What is the purpose of transcription in gene expression?

Back

The purpose of transcription is to transcribe the information in the DNA sequence into mRNA for use by the cell.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template that carries the genetic code from DNA to the ribosome, where proteins are synthesized.

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 start codon?

Back

The start codon is AUG, which signals the beginning of translation and codes for the amino acid methionine.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into the amino acid sequence of proteins.

Front

What is the role of ribosomes in translation?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into polypeptides based on the mRNA sequence.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.
