Unit 4- Proteins

Front

What is a codon?

Back

A codon is a sequence of three nitrogen bases in mRNA that specifies a particular amino acid.

Front

How many nitrogen bases make up a codon?

Back

3

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings the correct amino acid to the ribosome during 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 direct result of an error in transcription?

Back

The codon sequence is incorrect.

Front

What type of biomolecule does DNA provide the instructions for building?

Back

Proteins.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are the building blocks of proteins?

Back

Amino acids.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized.

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.
