q/a
what is the monomer of DNA ?
nucleotides
What kind of organic molecule is DNA?
Nucleic acids
How does DNA store the genetic code
in the sequence of the DNA nucleotides

phosphate group
dexyribose sugar
nitrogen base

A goes with what
C goes with what
G goes with what
T goes with what
T
G
C
A
What does diploid
each cell has two sets of chromosomes
if one cell undergoes mitosis, how many cells do you end up with
Two
what is mitosis
The process of cell division when one cell divide into two
how do the new cells compare to the cells you started with
They are identical
What is asexual reproduction
unicellular ( single - cells ) organisms
Prophase
prepare to divide
Metspahes
Middle
Anaphase
Apart
Telophase
two new cells
interpahes
incomplete cell
What is DNA replication
DNA replication is the process by which 2 identical cells of DNA are made
What are complementary strands
Two strings of DNA with opposite matching base
What is genetic code
The sequence of the nucleotide bases
Explain the steps of DNA replications
Helixase breaks the hydrogen bond between the complementary base unzipping the DNA. Then DNA polymerase attaches new base to the old base then ligas attaches the DNA pieces together
What is the result of the DNA replication
Two identical DNA molecules
Three parts of the nucleotide
phosphate sugar base connect base sugar phosphate
what did waston and crick work on
waston and crick work together yo gather information on DNA
What did Franklin do
Found that DNA is a helix chargaff showed A-T,C-G base pairing
Define cancer cell
Cancer cells do uncontrolled mitosis forming a mass of dividing cells is call a tumor
