Mitosis and Miosis
Body cells and Gamete cells go through what processes?
Mitosis and Meiosis
What does DNA stand for?
Deoxyribonucleic acid
Who is called 'The Father of Heredity'?
Gregor Mendel
Why do we need to know anatomical position?
Without it, if someone changes posture, terms like 'left' or 'down' wouldn't do any good.
What is the sour liquid that the liver produces called?
Bile
What are the phases of Mitosis and Meiosis?
Mitosis- Prophase, Metaphase, Anaphase, and Telophase.
Meiosis- Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II, and Telophase II.
Which scientists were known for making the model of DNA?
Watson and Crick
True or False:Homozygous alleles mean two same alleles
True
True or False: Superior means towards the head
True
What are the frog teeth on the roof of the mouth called?
Vomerine teeth
What are Haploid and Diploid cells?
Haploid- Half cells
Diploid- Double cells
What makes up sides of the DNA ladder?
Sugar and Phosphate
What is the difference between a genotype and a phenotype?
Where do the palms face in anatomical position?
Forward
What is movement in the stomach called?
Peristalsis
True or False:No one is exactly like the other scientifically
False; Identical twins have the exact same DNA due to Meiosis
What are the nitrogenous bases in DNA?
Adenine and Thymine
Cytosine and Guanine
What are the three principles of heredity?
2)Everyone has two alleles for a trait, and then the allele pairs separate.
3)The inheritance of a certain trait doesn't affect the inheritance of a different trait.
Is the elbow distal to the hand (in anatomical position)?
No, it's proximal.
What is the function of the small intestine?
To chemically break down food and absorb nutrients into the bloodstream.
Which phase of Meiosis allows no one (except for Identical twins) to have the same DNA?
Prophase I
How does DNA copy itself?
The hydrogen bases are ripped apart, unzipping the DNA ladder. Then, a temporary piece of RNA is added. After that, an enzyme called DNA polymerase binds to the RNA, and attaches nucleotides to make a new strand. The RNA is then replaced with DNA.
What is complete and incomplete dominance?
Complete- When the phenotype only expresses the dominant allele
Incomplete- When the dominant and recessive allele blend together, or a mix of both separately.
Name something posterior to the heart
The spine
To absorb water and electrolytes from remaining food, and convert it into waste.
