DNA
DNA stands for
Deoxyribo Nucleic Acid
What is an allele
matching half of gene
change in species over generations to better survive in environment
adaptation
control center
nucleus
results in the formation of gametes (haploid) cells
meoisis
RNA stands for
Ribo Nucleic Acid
strong allele
dominant
cells
produces energy
mitochondria
results in the formation of diploid cells
mitosis
The shape of DNA
Double Helix
hidden allele
recessive
universal solvent
except
water
fat, lipid, oil
bubble like selectively permeable membrane
cell membrane
First 3 steps in mitosis
1 interphase
2 prophase
3 metaphase
2 steps in DNA replication
1. Unzip
2 RNA builds matching dna strand
Code for alleles
Dom. capital
Rec. small letter
running from predator
response to stimulus
produces proteins
ribosomes
last 3 steps in mitosis
4. anaphas
5. telephase
6 cytokinesis
Three ways DNA mutates
addition
deletion
substitution
Three types of allele combinations and the effect
Homozygous dom dominant trait expressed
Homozygous recessive recessive trait expressed
heterozygous dominant trait expressed
ability to produce like offspring
reproduction
Two types of cellular reproduction and result
sexual/ unique offspring
asexual /clone
What are cell membranes made of?
lipids, fats, oil
