Molecular Biology Concepts Assessment

Front

What is transposase?

Back

An enzyme that catalyzes the cutting and resealing of DNA, translated from insertion sequences.

Front

What is feedback inhibition?

Back

A regulatory mechanism where a compound binds to the allosteric site of an enzyme, inhibiting its activity.

Front

What is DNA ligase?

Back

An enzyme that makes covalent bonds between the sugar of one nucleotide and the phosphate groups in another nucleotide in DNA.

Front

What is the structure of DNA?

Back

DNA is constructed of two strands of nucleotides running in an antiparallel configuration.

Front

What does it mean for a colony to be streptomycin-resistant?

Back

It means the colony can survive in the presence of streptomycin, an antibiotic.

Front

What is the role of RNA polymerase?

Back

An enzyme that synthesizes RNA from a DNA template during transcription.

Front

What is competitive inhibition?

Back

A type of enzyme inhibition where a molecule competes with the substrate for binding to the active site.

Front

What is the function of DNA helicase?

Back

An enzyme that unwinds the DNA double helix during DNA replication.

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.
