Protein Synthesis

Front

What is protein synthesis?

Back

The process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome.

Front

What is translation?

Back

The process by which ribosomes synthesize proteins using the mRNA sequence as a template to assemble amino acids.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic code from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during translation, matching them to the mRNA codons.

Front

What are ribosomes?

Back

Cellular structures where protein synthesis occurs, composed of rRNA and proteins, and can be found in the cytoplasm or attached to the endoplasmic reticulum.

Front

What is the genetic code?

Back

A set of rules that defines how the sequence of nucleotides in mRNA is translated into the sequence of amino acids in proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

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 are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals during protein synthesis.
