Which of the following is true of the leading strand?

A specific cellular activity, triggered by a signal, is which stage of cell signaling?

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.]
