Protein Synthesis and DNA mutations

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 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 codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids or stop signals 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 a mutation?

Back

A mutation is a change in the DNA sequence that can affect how genes function, potentially leading to changes in protein synthesis.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotide pairs are added to a DNA sequence, which can alter the reading frame of the gene.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotide pairs are removed from a DNA sequence, which can also alter the reading frame.

Front

What is a silent mutation?

Back

A silent mutation is a change in the DNA sequence that does not alter the amino acid sequence of the resulting protein.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide in the DNA sequence is replaced with another, which may or may not affect the protein produced.
