COMPREHENSIVE GENERAL BIOLOGY
STUDY GUIDE




Interkinesis (nothing happens) - CORRECT ANSWER --no chromosome
replication occurs because the chromosomes are already replicated

* does NOT got through this phas Functions of cell division - CORRECT
ANSWER -reproduction
growth and development
tissue renewal


Genome

Prokaryotic vs Eukaryotic - CORRECT ANSWER -


Ploidy - CORRECT ANSWER -number of sets of chromosomes in a cell


Haploid - CORRECT ANSWER -


what are three functions of cell division - CORRECT ANSWER -1.
reproduction

,2. growth and development
3. tissue renewal


genome - CORRECT ANSWER -all DNA in cell/gene instructions
-Prokaryotic cells- single circular DNA
-Eukaryotic cells- several linear DNA


chromosome - CORRECT ANSWER --DNA packaged tightly
-chromosomes consist of chromatin (DNA & proteins)
- human chromosome # = 46


chromatin - CORRECT ANSWER -the material of which chromosomes of
organisms other than bacteria (eukaryotes) are composed of
-contains:
Protein, RNA, & DNA


Ploidy - CORRECT ANSWER -number of sets of chromosomes in a cell


During cell cycle: starting ploidy = ending ploidy


n->n
2n->2n
100n -> 100n

, Haploid (n) - CORRECT ANSWER -having a single set of unpaired
chromosomes
2n = 46
this means:
n=23
n=23


diploid (2n) - CORRECT ANSWER -2 sets of each gene
2 full sets of chromosomes
2n=46
this means 1 set of dad goes with one set of mom


gametes - CORRECT ANSWER -sex cells
humans = 46 chromosomes
22 automosomes and 1 sex cell
22 autosomes and 1 sex cell = 46


Prokaryotic cell division - CORRECT ANSWER -binary fission: Double in size
& split


splits in 2, exact copies, quick and efficient with few mutations, but reduces
the amount of genetic variation


Eukaryotic cell cycle (Division) - CORRECT ANSWER -Interphase (Growth
and DNA Rep)
