Transcription/Translation/Mutations STAAR Review

Front

What is the purpose of transcription in the cell?

Back

To transcribe information in the DNA sequence for use by the cell.

Front

What is the complementary DNA strand for the sequence ATCG?

Back

TAGC

Front

What is the role of mRNA in protein synthesis?

Back

To carry the genetic code from DNA to the ribosome for protein synthesis.

Front

How do mutations affect traits in organisms?

Back

Mutations can change the sequence of nucleotides in DNA, leading to differences in traits.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the significance of the genetic code?

Back

The genetic code determines the sequence of amino acids in proteins, which affects an organism's traits.

Front

What happens during translation?

Back

During translation, the mRNA is read by ribosomes to synthesize proteins.

Front

What is a mutation?

Back

A mutation is a change in the nucleotide sequence of DNA.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where mRNA is translated into proteins.
