Chromatin - Answer Open or strung-out DNA
Normal form of DNA
90% of the time DNA is in this form
Double Helix - Answer Two strands of DNA with nucleotide base pairs
2nm
Nucleosomes - Answer Made of histones (proteins)
8 histones make up a block, DNA is wrapped around twice
10 nm
Tight Helical fiber - Answer coiling of the nucleosome string
Put together in the middle of two nucleosomes and it forms a knot
30 nm
Looped Domains - Answer 30-nm fiber forms loops that attach to a protein chromosome
scaffold, making up a 300-nm fiber
Chromatids - Answer Each side of a chromosome
Each side is identical
700 nm
1400 - Answer How many nm is a whole chromosome?
Chromosomes - Answer Put in this form so you can divide it equally
In in this form 10% of the time
, Homologous pair - Answer Same genes on the same chromosome
They contain the same genes but they're not identical
22 - Answer How many homologous pairs do males have?
23 - Answer How many homologous pairs do females have?
Ploidy - Answer number of sets of chromosomes in a cell
Haploid - Answer single set of unpaired chromosomes
--- sex cells
Diploid - Answer 2 sets of chromosomes
Polyploidy - Answer multiple sets of chromosomes (more than 2)
Walther Flemming - Answer Studied movement in chromosomes during mitosis in ANIMALS
Eduard Strasburger - Answer Studied movement of chromosomes during mitosis in PLANTS
Prokaryotes - Answer No nucleus
Single celled
Domains bacteria and archaea
1 chromosome
Circular DNA
Can't do mitosis
Binary Fission - Answer prokaryotic cell division
