Genetics
An organsim's traits
follow patterns of inheritance
which can be complex such as
codominance
polygenic inheritance
incomplete dominance
which can be modeled by
pedigrees
punnett squares
are determined by information stored in
DNA
can be altered resulting in
mutations
stores instructions for making proteins that are produced by
RNA
are passed from parent to offspring, which is called
heredity
and are controlled by
recessive factors
dominant factors
Types of Mutations
Substitution
The C-G base pair has been replaced with a T-A pair.
Deletion
Three base pairs have been removed. Other base pairs will move in to take their place
Insertion
Three base pairs have been added
DNA
parents
genes
child genes
birth
livng
cells
chromosomes
reproduction
inheritence
Kids genes
Half and half
They grow
parents
It's a cycle
cells
Sperm and egg cells
Chromosomes
How DNA Makes a Protein:
mRNA nucleotides pair up with DNA nucleotides.
Completed RNA can move to the cytoplasm.
tRNA carries amino acids to the ribosome.
rRNA helps form chemical bonds that attach one amino acid to the next.
Amino acids make a protein
Cross-Pollination: Mendel and His Peas
Mendel removed the stamens from the purple flower.
He transferred pollen from the stamens of the white flower to the pistil of the purple flower.
The pollinated pistil of the purple flower grew into a pea pod. Then Mendel planted the peas.
The peas grew into plants.
