Transcription and Translation

Front

What is transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA).

Front

What is translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to synthesize proteins, involving ribosomes and transfer RNA (tRNA).

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 the role of ribosomes in protein synthesis?

Back

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

Front

What is the start codon?

Back

The start codon is the first codon of a messenger RNA (mRNA) transcript that is translated by a ribosome, typically AUG, which codes for the amino acid methionine.

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.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins, linked together by peptide bonds.

Front

What is a promoter region?

Back

A promoter region is a specific sequence of DNA that initiates transcription of a particular gene, providing a binding site for RNA polymerase.

Front

What is the function of tRNA?

Back

Transfer RNA (tRNA) transports specific amino acids to the ribosome during translation, matching them to the corresponding codon in mRNA.

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.
