Steps of Cell Division
The middle phase, where the chromosomes line up in the middle.
What is Metaphase?
The structure of DNA. The shape it takes.
What is a double helix?
If a white moth has a mutation to make it black and blend in with bark, that mutation is...
What is helpful?
The father of Genetics, studied pea plants and their offspring.
Who is Gregor Mendel?
Having the same two alleles also known as a purebred.
What is Homozygous?
The first phase where the nucleus starts to dissolve and chromosomes separate and make copies.
What is Prophase?
A change in the DNA.
What is a Mutation?
A base pair that has a wrong partner or a section is not correctly matched up with another.
What is a translation?
Invented the Punnett Square.
Who is Reginald Punnet?
A gene combination of one dominant and one recessive allele.
What is Heterozygous?
The phase in which the one cell splits into two.
What is Cytokinesis?
The other pair to Guanine in one of the paired bases of DNA.
What is cytosine?
If a chicken has a mutation that makes his wings shorter that mutation could be...
What is Neutral?
Discovered the paired bases of DNA.
Who is Erwin Chargaff?
A trait that is physically visible in an organism.
What is a Phenotype?
This step only occurs in mitosis.
What is Interphase?
The other pair to Adenine in one of the paired bases of DNA.
What is Thymine?
Extra base pair inserted into the DNA sequence.
What is an Insertion?
Received the Nobel Prize for discovering the structure of DNA.
Who is James Watson and Francis Crick?
A combination of alleles that represents the genetic makeup of an organism.
What is a Genotype?
The phase where the chromosomes pull back to the opposite sides of the cell.
What is Anaphase?
The backbone for DNA.
What are Sugars and Phosphates?
One base pair that gets deleted from the DNA sequence.
What is a Deletion?
First person to use x-ray diffraction to see the helix structure of DNA.
Who is Rosalind Franklin?
Different forms a gene can take.
What is an allele?
