What phase does DNA replicate?
S phase
The stage interphase when the cell prepares for mitosis.
What is the G2 stage?
Chromosomes are made of DNA. They contain segments of codes called...
genes
DNA is unzipped by this enzyme
helicase
The stage of interphase when DNA replicates
What is the S phase?
true or false: chromosomes can be EITHER in the shape of a single line OR an "x"
true
After the two DNA strands are unzipped, another enzyme, primase, lays down what?
RNA primer
The longest stage of the cell cycle.
What is Interphase?
condensed "thread like" structures that carry genetic information from cell to cell are called
chromosomes
What is DNA polymerase responsible for?
laying down complimentary bases/ nucleotides
During this phase the cell grows and synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division.
What is G1 Phase?
What are sister chromatids?
when a chromosome makes a copy of itself
connected at centromere/ kinetochore
After the new strands of DNA are built, which enzyme seals the sugar phosphate backbone?
Ligase
Mature cardiac cells and nerve cell often enter this phase, during which they are inactive and are not preparing to divide.
What is the G0 phase?
What does "homogenous chromosomes" mean?
same or similar genes
