Transcription and Translation of DNA

Front

What is transcription in the context of DNA?

Back

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

Front

Where does transcription occur in a eukaryotic cell?

Back

Transcription occurs in the nucleus of eukaryotic cells.

Front

What is translation in the context of protein synthesis?

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 a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

How many nucleotides are in a codon?

Back

A codon is made up of 3 nucleotides.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where it is translated into a protein.

Front

What is the sugar component of DNA nucleotides?

Back

The sugar in DNA nucleotides is called deoxyribose.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.

Front

What is the start codon and its significance?

Back

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

Front

What is the difference between DNA and RNA?

Back

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