DNA and Protein Synthesis

Front

What is a codon?

Back

A codon is a sequence of three nitrogen bases in DNA or RNA that codes for a specific amino acid.

Front

How are amino acids linked together during translation?

Back

Amino acids are linked together during translation by creating peptide bonds.

Front

What is the resulting mRNA from the DNA sequence GAT-TAC-AGA-TTA-CAT?

Back

The resulting mRNA is CUA-AUG-UCU-AAU-GUA.

Front

What two components make up the DNA nucleotide backbone?

Back

The DNA nucleotide backbone is made up of deoxyribose sugar and phosphate group.

Front

Which type of RNA delivers the genetic code to the ribosome?

Back

mRNA (messenger RNA) delivers the genetic code to the ribosome.

Front

What is the role of tRNA in protein synthesis?

Back

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

Front

What is the function of rRNA in the cell?

Back

rRNA (ribosomal RNA) forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is transcription in the context of protein synthesis?

Back

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

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 is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein synthesis.
