Cell Cycle
In which phase does DNA replicate?
S phase
What is osmosis?
The movement of water.
Which biomolecule is the body’s primary short-term energy source and includes sugars such as glucose?
Carbohydrates
DNA to DNA
Adenine (A) matches with __________?
Cytosine (C) matches with __________?
Adenine (A) matches with Thymine (T)
Cytosine (C) matches with Guanine (G)
Long ears (E) is dominant over short ears in dogs. What genotype(s) represents the recessive trait?
ee
Name the phases of interphase in order
G1, S, and G2
If a bag has 0.4 M of sucrose solution and the outside is 0 M, where will water flow?
Water will flow into the bag, a hypotonic solution.
Which biomolecules are used for insulation, long-term energy storage, and building membranes.
Lipids
Label the parts of DNA on your tracker.
A = Sugar (Deoxyribose)
B = Phosphate group
C = Nitrogenous Base
D = Nucleotide
Brown fur (B) is dominant over white fur (b). What is the parent cross if a homozygous dominant parent is crossed with a heterozygous parent?
Homozygous dominant = BB
Heterozygous = Bb
Parent Cross:
BB X Bb
In which phase does the cell divide?
Mitosis
If a bag has 0.4 M of sucrose solution and the outside is 0.4 M, where will water flow?
Water will flow both ways, isotonic solution.
Which biomolecules are made of amino acids and perform functions such as transport, structure, and enzyme activity.
Proteins
What part of DNA determines unique traits/characteristics?
Nitrogenous bases (A, T, C, G)
Long ears (E) are dominant over short ears (e) in dogs. If a pure-blood long eared dog mated with a short ear. What percentage of their kids will have short ears?
0 %
How can you tell a cell is in prophase?
(Show me with your hands too!)
When a cell is condensed; Thick DNA
If a bag has 0.4 M of sucrose solution and the outside is 2 M, where will water flow?
It will flow out of the bag to the outside, a hypertonic solution.
Which molecules store genetic information (DNA/RNA)?
Nucleic acids
Original:
TTA AAT GGC
Mutation:
TTA AAT GCC
What type of mutation is this?
Substitution
If brown fur (F) is dominant over white fur (f). Two heterozygous parents are crossed, what percentage of their offspring will have brown fur?
75%
Can you generalize what happens in each of these phases:
1. G1
2. S
3. G2
4. Mitosis
1. G1 = Cell growth; organelles doubled
2. S = DNA replicated/duplicated/copied
3. G2 = Cell growth; Preparing for Mitosis (checkpoints)
4. Mitosis = PMAT = Cell nucleus divides
If you force something against a concentration gradient, what type of transport is it called?
Active transport
Which biomolecules are steroids made of?
Which biomolecules are enzymes made of?
Steroids are made up from lipids
Enzymes are made up from proteins
Original:
TTA AAT GGC
Mutation:
TTA ATG GCC
What type of mutation is this?
Deletion
**A was deleted
Sickle-cell anemia (a) is an autosomal recessive disease. If a parent afflicted with sickle cell anemia has a child with another individual who is a carrier. How likely is it that their child will have sickle-cell anemia?
Parent cross: aa x Aa
