Which of the following best describes how the Cas9 protein determines where to cut a DNA strand?

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

Which site of a ribosome releases tRNA molecules after they have added their amino acid to the growing polypeptide strand?

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-UGC-AAG-GCA-UGA – 3′ Accessible Codon Chart Long Description.pdf   

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?
