DNA
Adenine binds to
What is thymine
Where does Replication take place?
Only in the Nucleus
what phase of the cell cycle does DNA replication take place
s phase of interphase
True or false if mitosis did not happen, Body tissues would not be able to repair themselves?
True
Guanine binds to
What is Cytosine
DNA is a polymer composed of monomers called?
What are nucleotides
Which phase does cytokinesis begin?
What is Anaphase
True or false if mitosis did not happen, the production of gametes (sperm and egg) would not occur?
False
What two bases are Purines
What is Adenine and Guanine
What is the complimentary DNA strand of ATGCCT?
What is TACGGA
What is the mutation in Albinism? Explain the protein that is affected and what results because of this.
The mutation for Albinism is in the formation of an enzyme. This enzyme Melanocyte Tyrosinase is not formed correctly, leaving the person unable to synthesize the pigment Melanin.
Interphase+Prophase+Metaphase+Anaphase+Telophase =
What is the cell cycle
True or false, if mitosis did not happen, organisms would be single celled?
True
What is the base that is not found in DNA
What is Uracil
What is the central dogma of Biology (regarding DNA)
DNA--> RNA-->protein
What effect does a mutation have on DNA?
And on protein structure?
Change in the DNA sequence
Possible change in the protein structure depending on the type of mutation
What is the function of the nucleus?
What is to store DNA
What are the three functions of mitosis
Growth, Repair and asexual reproduction
Which 2 bases are the Pyrimidines
What is Cytosine and Thymine
Why is messenger RNA needed for protein synthesis
What is DNA cannot leave the nucleus
Explain the mutation in sickle cell anemia?
Single base substitution resulting in a different amino acid being picked up. Hemoglobin protein is assembled incorrectly.
Why do all the body cells have the same DNA?
What is they all started from the same cell (stem cell)
How is it possible that many different cell types can result from a single cell?
Cell differentiation
