DNA, RNA and protein synthesis

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions for the development and function of living things. It serves as a template for mRNA during transcription.

Front

What is mRNA and its function?

Back

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

Front

What is the process of transcription?

Back

Transcription is the process of copying a segment of DNA into mRNA. It occurs in the nucleus of the cell.

Front

What is the process of translation?

Back

Translation is the process where the mRNA code is read by ribosomes to synthesize proteins, using tRNA to bring the appropriate amino acids.

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 an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that is complementary to a codon in mRNA, allowing for the correct amino acid to be added during translation.

Front

What is the significance of amino acids in protein synthesis?

Back

Amino acids are the building blocks of proteins. They are linked together in a specific sequence to form a protein based on the mRNA code.

Front

What is the role of tRNA in translation?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome and matches them to the corresponding codon on the mRNA.

Front

What is the structure of a protein?

Back

Proteins are made up of one or more polypeptide chains that fold into a specific three-dimensional structure, which determines their function.

Front

What is the difference between transcription and translation?

Back

Transcription is the process of creating mRNA from DNA, while translation is the process of synthesizing proteins from mRNA.
