DNA, Transcription, Translation, and Mutations review

Front

What is a benefit of mutations?

Back

Mutations can add new genes, which may lead to beneficial traits or adaptations.

Front

Which statement is FALSE about DNA and RNA?

Back

DNA has uracil and RNA has thymine.

Front

In RNA, Uracil pairs with which base?

Back

Adenine.

Front

What process creates mRNA?

Back

Transcription.

Front

What is any change in the sequence of DNA called?

Back

Mutation.

Front

What are the building blocks of DNA and RNA?

Back

Nucleotides.

Front

What is the primary function of mRNA?

Back

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

Front

What is the role of tRNA in translation?

Back

tRNA brings amino acids to the ribosome and matches them to the codons in mRNA.

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.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.
