Chapter 16: Genetics
Replications of DNA
replicon
double helix is cut
Two strands separate
forms a "bubble"
primer RNA
free nucleotides diffuse
pair with bases
polmerized into short pieces
10 nulcleotides long
DNA polymerase
DNA synthesizing enzyme
semiconservative repication
adds deoxyribonucleotides
each strand is a template
results in a double helix
replication fork
ligated into 2 new molecules
Dihybrid Crosses
Independent assortment
Crossing over
linked
recombinant chromosomes
parental type chromosomes
Other Aspects of Inheritance
maternal inheritance
mitochondian genomes
plastid
variegation
pollen parent
ovule parent
lethal alleles
Gene Families
polyploid
nondisjunction
paralogs
Mutations
point mutation
deletion
insertion
inversion
Causes
mutagen
something that causes mutations
chemicals
UV light
X-rays
radiation
Transposable elements
insertion sequences
a few thousand pairs long
contain gene codes for enzymes
transponson
longer than insertion
carries genes that code for proteins
Somatic Mutations
happens in cells that never lead to sex cells
not passed on to offspring
Monohybrid Crosses
Incomplete Dominance
parental generation
First filial generation
Second filial generation
homozygous
heterozygous
Heterozygotes
selfing
Punnett square
Complete Dominance
dominant
recessive
test cross
pure bred lines
multiple alleles
Multiple Genes for One Character
epistasis
quantitative trait loci
pleiotropic effects
