DNA Replication and Protein Synthesis

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are the building blocks of proteins?

Back

Amino acids are the building blocks of proteins.

Front

What is the genetic code?

Back

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

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is translation?

Back

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

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet that signals the end of protein synthesis.
