Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is a codon?

Back

A codon is a sequence of three nucleotide bases in mRNA that codes for a specific amino acid.

Front

What is the role of AUG in mRNA?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

What is the process of transcription?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What is the genetic code?

Back

The genetic code is the set of rules by which information encoded in mRNA is translated into proteins, consisting of codons.

Front

What is the significance of the stop codon?

Back

A stop codon signals the termination of protein synthesis, indicating that the ribosome should release the newly formed polypeptide.

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.

Front

What are amino acids?

Back

Amino acids are the building blocks of proteins, linked together by peptide bonds to form polypeptides.

Front

What is translation in protein synthesis?

Back

Translation is the process by which ribosomes read the mRNA sequence and assemble amino acids into a polypeptide chain.

Front

What is the function of ribosomes?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into proteins.
