Replication
This strand of DNA is replicated discontinuously, and requires addition of Okazaki fragments.
What is a lagging strand
Transcription has three stages. Initiation, _______, and termination.
What is elongation

What is the protein that exhibits bright green fluorescence when exposed to light?
GFP (Green Fluorescent Protein)
in biology, this is the study of "stable" changes in cell function that do not involve alterations in the DNA sequence
