A student is looking at cells under the microscope. The cells are from an organism that has a diploid number of fourteen. For one particular slide, a cell has 14 replicated chromosomes (14 pairs of sister chromatids) aligned in a double row along the metaphase plate. Which of the following statements accurately describes this particular cell?

Blue white screening involves growing up transformed cells on plates that include both an antibiotic and X-Gal.  Recombinant colonies are expected to be. . .

What mechanism is used by a bacterial cell to fit its DNA into the nucleoid region?

Bacteria are grown in 15N (heavy) medium and then transferred to 14N (light) medium and are allowed to replicate for 1 generation. The DNA is subsequently isolated and centrifuged in a CsCl2 gradient to yield what type of gradient band(s)? 

If the sequence of a section of DNA is 5′-CGCAACTAC-3′, what is the correct sequence for the opposite strand?

A protein that binds to the DNA and inhibits transcription is called

Gene cloning

The term “genetic code” refers to

Which proposed mechanisms of DNA replication maintained that the original parental strands were unzipped, used as a template to make a new copy, and then put back together to reform the original parental DNA strand?

What is the MOST important reason a cell exhibits tight transcriptional control over the regulation of gene expression?
