DNA and RNA
DNA replication is a process by which DNA is copied i a cell before a cell divides by mitosis, meiosis, or binary fission.
Replication Fork, a Y-shaped region on a replicating DNA molecule where new strands are growing.
Origin of Replication: SIte where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.
DNA: Polymerase: An enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain.
DNA polymerase I: Enzyme, Removes RNA primers and replaces them with the appropriate nucleotides during DNA replication.
DNA III: using parental DNA as a template synthesize DNA strand by covalently adding nucleotides to the 3' end of a preexisting DNA or RNA primer

Gene Expression: The process by which DNA directs the synthesis of proteins of, in some cases, just RNAs. Includes 2 staged - transcription and translation.
RNA has 3 out 4 of the amino acids DNA has (A,C,G) Instead of T, it has Uracil(U)
