Biochemistry 4116 TA Practice Flashcardzes - Practice Quiz 1

Front

What is the most abundant type of RNA in the cell?

Back

rRNA (ribosomal RNA) is the most abundant type of RNA in the cell.

Front

What is one functional consequence of RNA forming higher-order structures?

Back

RNA can act as enzymes (ribozymes) due to its ability to form higher-order structures.

Front

What does the linking number describe in DNA?

Back

The linking number describes the number of times one DNA strand wraps around the other in a closed DNA molecule.

Front

What is the process by which DNA is copied into RNA?

Back

Transcription is the process by which DNA is copied into RNA.

Front

What is the correct base pairing in DNA?

Back

The correct base pairing in DNA is A-T (adenine-thymine) and G-C (guanine-cytosine).

Front

Define transcription in the context of molecular biology.

Back

Transcription is the process of synthesizing RNA from a DNA template.

Front

What role does rRNA play in the cell?

Back

rRNA is a key component of ribosomes, which are the sites of protein synthesis.

Front

What are ribozymes?

Back

Ribozymes are RNA molecules that can catalyze chemical reactions, similar to enzymes.

Front

Explain the significance of the double helix structure of DNA.

Back

The double helix structure of DNA allows for the stable storage of genetic information and facilitates replication.

Front

What is the difference between transcription and translation?

Back

Transcription is the synthesis of RNA from DNA, while translation is the synthesis of proteins from RNA.
