Biology Chapter 6 test review

Front

What is the main difference between DNA and RNA?

Back

DNA is a double-stranded molecule that contains thymine, while RNA is a single-stranded molecule that contains uracil.

Front

What cellular organelle is responsible for protein synthesis?

Back

The ribosome reads RNA strands and assembles amino acids into proteins.

Front

What molecule do cells use to temporarily store energy?

Back

Adenosine triphosphate (ATP) is the molecule used for temporary energy storage.

Front

What molecule stores genetic information in the nucleus?

Back

DNA (deoxyribonucleic acid) stores genetic information within the nucleus of a cell.

Front

What is the process of copying an existing DNA molecule called?

Back

Replication is the process of making a new DNA molecule by copying an existing one.

Front

What sugar is found in RNA?

Back

Ribose is the sugar found in RNA.

Front

What is the role of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands during replication.

Front

What is the function of ribosomes in cells?

Back

Ribosomes are responsible for translating mRNA into proteins.

Front

What is the difference between adenosine triphosphate (ATP) and adenosine diphosphate (ADP)?

Back

ATP has three phosphate groups and stores more energy than ADP, which has two phosphate groups.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.
