SOL Review: Bio. 5 & 2 DNA, RNA, & Mutations

Front

Which nitrogenous base is NOT found in RNA?

Back

Thymine is not found in RNA; it is replaced by Uracil.

Front

What is a mutation?

Back

A mutation is any change in the sequence of DNA.

Front

What does DNA stand for?

Back

DNA stands for Deoxyribonucleic acid.

Front

What is the process of transcription?

Back

Transcription is the process where DNA is copied into mRNA.

Front

What type of RNA carries the DNA message to the ribosomes?

Back

mRNA (messenger RNA) carries the DNA message out of the nucleus to the ribosomes.

Front

What is the role of tRNA in protein synthesis?

Back

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

Front

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

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 the function of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into proteins.

Front

What is the significance of mutations in evolution?

Back

Mutations can introduce genetic variation, which is essential for evolution.
