What is one step that occurs in eukaryotic transcription but not in prokaryotic transcription?

A cap is added to the 5' end of the RNA, and the RNA is spliced

The monomers of RNA are:

Nucleotides

Your skin cells will most likely have the same DNA sequence as

The cells that make up the lining of your intestine

What statement correctly defines gene expression?

Gene expression occurs when a gene is transcribed and (usually) translated.

What process produces RNA polymers?

Transcription

The Central Dogma of Molecular Biology is concerned with...

The flow of genetic information within a cell

What is NOT a function of the 5' G cap of eukaryotic mRNA?

to aid in transcription initiation

One difference between DNA and RNA is that 

RNA has a different sugar in its sugar-phosphate backbone than DNA does

What type of protein helps to guide RNA polymerase to the correct starting location in transcription initiation?

 

proteins called transcription factors

What correctly summarizes the flow of information within a cell?

DNA → RNA → protein

A gene is expressed when it is

transcribed and translated

What determines the sequence of nucleotides in mRNA?

the sequence of nucleotides in the template DNA

Which enzyme synthesizes RNA strands?

RNA polymerase
