DNA and Gene Expression

Front

What forms the backbone of the DNA ladder?

Back

Deoxyriboses and phosphates.

Front

What is the role of transcription factors in gene expression?

Back

Transcription factors can induce or repress transcription.

Front

Which is larger: guanine or cytosine?

Back

Guanine is larger because it's a purine.

Front

What must bind to a gene's promoter to initiate transcription?

Back

RNA polymerase must bind to the gene's promoter.

Front

What is DNA a polymer made of?

Back

DNA is a polymer made of nucleotides.

Front

What are the two main types of nucleotides in DNA?

Back

Purines and pyrimidines.

Front

What are the purines found in DNA?

Back

Adenine and guanine.

Front

What are the pyrimidines found in DNA?

Back

Cytosine and thymine.

Front

What is the function of RNA polymerase?

Back

RNA polymerase synthesizes RNA from a DNA template.

Front

What is the significance of the promoter region in gene expression?

Back

The promoter region is where RNA polymerase binds to initiate transcription.
