Prophase
Chromosomes condense, nuclear membrane disolves
Mitosis
Makes diploid, repairs damaged cells and for growth
Thymine
In DNA complementary base pairing adenine always pair with ___
Uracil
In RNA complementary base pairing adenine always pairs with __
Guanine
Beside cytosine, ____ is also found in both DNA and RNA
Gene
A piece of DNA that codes for a protein and determines a trait
S-Phase
DNA is copied in the cell cycle
Prophase - 1
Homologous chromosomes pair up and crossing over occurs
Hydrogen bond
This bond holds two strands of DNA at the bases
Helicase
An enzyme that unwinds and unzips the double helix
Rosalind Franklin
Used x-ray diffraction photo that proved DNA is a double helix
Anaphase - 2
Sister chromatids are pulled to opposite sides of the cell
Meiosis
Makes gametes (haploids)
Anaphase - 1
Homologous chromosomes separate
Chromosomes
Made up of DNA and proteins
Metaphase
Chromosomes line up in the middle of the cell
DNA polymerase
An enzyme that uses free nucleotide and a template strand to form a new complementary DNA strand
Telophase
Nuclear membrane reforms and spindle fiber disappears
Cytokinesis
The cytoplasm splits
Protein
A macromolecule formed through transcription and translation
