Chapter 10 Flashcards
Karyotype is a particular array of
chromosomes in an individual organism
Karyotypes are arranged according to
size, staining properties, and location of centromere
Diploids have _ complete sets of chromosomes
2, 46 total chromosomes
Haploids have _ complete sets of chromosomes
1, 23 total chromosomes
A pair of chromosomes is
homologous, each one is a homologue
Chromosomes are composed of
chromatin
Chromosomes complex is made up of __ and ___
DNA and Protien
RNA is the site of
RNA synthesis
A typical human chromosome is…
140 million nucleotides long
In the nondividing nucleous, the 2 parts include the
Heterochromatin, and the Eurchromatin
Heterochromatin is __
expressed
Euchromatin is __
not expressed
___ promotes/guides the cooling of DNA
Nucleosome
Nucleosomes wrapped into higher, older coils are called
Solenoids
During mitosis, chromatin is solenoid arranged around a
scaffold protein to achieve maximum compaction
List the 5 phases of the Eukaryotic Cell Cycle
Gap 1 Phase, S Phase, Gap 2 Phase, Mitosis, Cytokenesis
Gap 1 phase is the
primary growth phase, longest
S Phase is the
replication of DNA
Gap 2 phase is where
organelles replicate and microtubules organize
Cytokenesis results in the
separation of 2 cells
Time it takes to complete a cell cycle
Duration
Mature cells take ___ to grow
LONGER
Growth occurs during what phases
G1, S, G2
Interphase inclues
G1, S, G2
