“A Cell’s Life”
Mendel… Mendel who?
Your-osis? No… meiosis!
It’s in my genes
It’s time to make the proteins
You say you want some evolution

The process by which a cell divides into two new daughter cells
Cell Division
The part of the cell cycle that occurs prior to cell division
The division of a cell’s nucleus
All parts (in order) of cell division (not just mitosis!!)
Prophase, Metaphase, Anaphase, Telophase & Cytokinesis
End result of cell division
Two identical diploid daughter cells
The tool used to predict outcomes of a genetic cross
Punnett Square
The different forms of a gene
The expected phenotypic ratio (or %) for offspring of two heterozygous tall pea plants
3:1 or 75% tall, 25% short
Rule that explains why all offspring of a pure-bred tall pea plant crossed with a short plant are tall
Principle of Dominance
States that genes for different traits can segregate independently when gametes are formed
Principle of Independent Assortment
The number of sets of chromosomes in a haploid cell
Chromosomes from the male parent that have a similar chromosome from the female parent
The process that occurs during Prophase I of meiosis that increases allele combinations on chromatids
Genes are more likely to be inherited together if this is true about the genes
If they are close together on the chromosome (they are linked)
The end result of meiosis (be specific)
Four haploid gametes that are genetically different
DNA is a nucleic acid made up of these building blocks
The process of DNA making a copy of itself
Replication (occurs before cell division)
These hold together the two strands of a DNA molecule
Hydrogen bonds
Describe the principle of base pairing
In DNA adenine only pairs with thymine, and guanine only pairs with cytosine
Name the parts of a nucleotide
5-carbon sugar (deoxyribose) phospate group and nitrogenous base
The three types of RNA
Messenger (mRNA), transfer (tRNA) & ribosomal (rRNA)
