Structures
Cell cytoplasm divides
What is cytokinesis (or M phase)?
This is the enzyme that "unzips the genes"
What is helicase?
The strands of DNA run in opposite directions - this is referred to as
What is antiparallel?
DNA replicates
What is the S phase?
Uses Helicase, DNA Polymerase, and DNA ligase
What is the lagging strand
Scientists that discovered DNA was a double-helix in shape
What is Watson and Crick?
The cell grows and carries out normal activities after division has occurred
What is the G1 phase?
A DNA segment that contributes to phenotype and/or function.
What is a gene?
Parent strand responsibility in DNA replication.
What is a template for DNA replication?
These are the fragments formed on the lagging strand by DNA Polymerase.
What are Okazaki fragments?
The stage that includes G1, S, and G2
What is interphase?
This is the enzyme that links all the bases on the lagging strand together
What is DNA Ligase?
Made up of 3 parts: sugar, phosphate, and nitrogen base
What is a nucleotide?
Each of the two DNA molecules is composed of one strand from the original molecule and one newly synthesized strand. (What type of replication?)
What is semi-conservative?
Cell preparation for division occurs
What is the G2 phase?
An organism's complete set of genetic instructions. Each _____ contains all of the information needed to build an organism.
What is a genome?
Random errors in DNA replication that lead to a change in the sequence of nucleotides.
What is a mutation?
