What is an Allele
cells that are haploid
What are Gametes (egg and sperm)
Paired chromosomes that have identical genes, one inherited from Mom, one from Dad
What is Homologous Chromosomes
Phase of mitosis and meiosis when two nuclei are formed
What is Telophase
A genetic term for what something looks like or what is expressed based on their genes
What is phenotype
Scientist that observed bacterial transformation (non-virulent bacteria became virulent)
Who as Griffith
What is meiosis
What is it called when Homologous chromosomes line up and exchange genetic material during meiosis
Crossing Over
Which phase of mitosis do chromosomes line up in the middle of the cell
What is metaphase
A genetic term for what the genetic sequence of a gene actually is
What is genotype
Scientist that took an x-ray picture of DNA that indicated a helix
Who was Rosalind Franklin
Scientists that discovered the double helix structure of DNA
Who were Watson and Crick
A heterozygous allele combination for a recessive disease is called:
What is a carrier
Crossing Over happens in which phase of Meiosis
What is Prophase I
An allele of a gene that is always seen as the phenotype
What is dominant
Scientist that showed DNA to be the transforming principle that Griffith observed in bacteria
Who was Avery
Enzyme that unwinds DNA before replication
What is Helicase
The complimentary bases that pair with Adenine and Guanine
What is Thymine and Cytosine
Part of the cell cycle that replicates DNA
What is Synthesis
A gene that is only shown as the phenotype when there are two of the same alleles on both chromosomes.
What is recessive
Scientists that used bacteriophages to confirm that DNA was the transforming principle
Who were Hershey and Chase
The three parts of a nucleotide
phosphate, sugar, base
Lab technique that separates DNA by size
What is gel electrophoresis
What is replication
The name of enzymes that cut DNA into small fragments based on specific nucleotide sequences
What are restriction enzymes
