Outline the process of RNA splicing. Then identify how this can be used to produce different proteins from the same DNA sequence through alternative splicing.

The binding of a ligand to a receptor protein is which stage of cell signaling?

The following image show a gel at the end of gel electrophoresis. Well 1 was filled with a control, the exact DNA sequence we are looking for. Wells 3 and 5 were filled with DNA extracted from two different samples. Which of these samples does not contain the DNA sequence we are looking for? Choose all that apply.         [Image ID: Gel with 6 wells, 3 used. Well 1 contains control. Well 3 contains Sample 1. Well 5 contains Sample 2. Bars are seen on the gel in 3 areas: top, middle, bottom. Well 1 shows only top bar, Well 3 shows top and middle, Well 5 shows top and bottom.]

DNA that is a combination from two different sources is known as what?

The enzyme (or, more broadly, family of enzymes) responsible for laying down DNA nucleotides using another DNA strand as a template is what?

Transcription is performed primarily by what enzyme?

Which viral life cycle involves incorporation of viral genetic material into the host’s chromosome for extended periods of time, with the viral genetic material being copied and passed on to all of the host’s offspring?

Which of the following molecules carries amino acids to their corresponding codons?

Which of these will deactivate in the presence of the molecule they are named for?
