Which of the following possesses a repressor protein bound to its operator sequence in its natural state?

The enzyme responsible for laying down an RNA primer at the start of a new DNA strand is what?

Which site of a ribosome holds the growing strand of amino acids?

In the eukaryotic cell proteins do not last forever. As they degrade, the change in their numbers affects their productivity and affects whether or not the processes they are responsible for continue to occur. This is an example of what type of gene regulation?

DNA possesses what type of charge?

True or false: Prokaryotic cells need additional molecules, called transcription factors, to bind to a promoter sequence before transcription can begin.

In the eukaryotic cell, after the transcription product leaves the nucleus it must join with a ribosome to continue the gene expression process. Various proteins and other molecules can bind to, or be attached to, the transcription product and can either help with this joining or hinder it. This is an example of what type of gene regulation?

What polypeptide would result from the translation of an mRNA strand with the sequence listed below? Use the provided codon chart to determine the amino acid sequence – you may list the amino acids either by their three letter abbreviation or by their full name. You should also identify the N terminus and C terminus of the sequence. For students who need it, the long description for the codon chart is linked beneath the image.    5′ – AUG-AGA-UCC-CAU-UGA – 3′ Accessible Codon Chart Long Description.pdf   

Gel electrophoresis commonly separates DNA fragments based on what property?

Which viral life cycle involves only the immediate takeover of host cellular machinery and production of new viruses?
