When cells go through meiosis, in which phase do the sister chromatids separate
What is meiosis II?

What does the enzyme helicase do?
Helicase "unzips" or unwinds DNA so that each strand can act as a template to synthesize a new complementary strand.

The alleles for polka dots are:

PP, Pp, and pp

The PP is ____________, the Pp is ___________ and the pp is _______________.

What is dominant homozygous, what is heterozygous, what is recessive?

A symbiotic relationship is when ________________
What is both organisms benefit?

The three blood types are:

Their alleles are:

What are A, B and O?

What are Ia, Ib and i?

The three main differences between meiosis and mitosis are:

What is:

1) Meiosis produces four daughter cells while mitosis produces two

2) Meiosis produces genetically different daughter cells due to crossing over while mitosis produces identical ones

3) Meiosis has two phases (meiosis I and meiosis II) while mitosis has only one

200

Leading strands are synthesized in the _____________ direction.

Lagging strands are synthesized in the _____________ direction.

__________ strands form fragments.

What is 5' to 3'?

What is 3' to 5'?

What is lagging strands?

A dog breed with a dominant genotype has black fur. The same breed that also has a dominant genotype has gray fur. The recessive genotype has white fur.

This is called ________________________.

What is incomplete dominance?
200
A commensalistic relationship is when ______________________
what is one organism benefits and the other is unaffected?
200

Genetic engineering is when ____________________________

Two benefits of genetic engineering:

What is a new organism is created by adding genes from a different organism?

What is 1) Can benefit by agriculture by help create disease-resistant crops

2) Can help treat diseases

The steps of mitosis and what happens during them are:

1) prophase- the microtubules assemble, chromatin condenses, nuclear envelope dissolves

2) metaphase- the chromosomes line up at the metaphase plate in the middle of the cell

3) anaphase- the spindle fibers pull the chromosomes apart towards opposite poles along the microtubules

4) telophase- the chromatids arrive at opposite poles of the cell, new membranes form around daughter cells

5) cytokinesis- cells pinch off

300
The enzyme DNA polymerase is responsible for ___________________________________.
What is "reading" the existing strand and adding complementary nucleotides to the new strand?
300
A woman with heterozygous (O/A) type A blood has a child with a man who has type O blood. The chance their child will have type O blood is:
What is 50 percent?
300
A biome is _________________________
What is a community of plants and animals that living in an environment with common characteristics?
300
Animals at the bottom of the food chain are called:
What are producers?

A DNA strand has the sequence:

ACGTCA

Its complementary sequence should be:

What is TGCAGT?
400

A certain animal species can have fur or no fur and polka dots or no polka dots.

Write out the alleles for fur and no fur and polka dots/no polka dots if having fur and having polka dots are both dominant:

Write out the genotype for an animal homozygous for fur and no polka dots:

What is F and f and P and p?

What is Ffpp?

What is anaphase of meiosis II?

A cell starts with 50 chromosomes and goes through meiosis. After meiosis I each daughter cell has _____________ chromosomes and ____________ chromatids; after meiosis II each daughter cell has _______________ chromosomes and ________________ chromatids.
25; 50; 25; 25

List the steps of DNA replication, including which enzymes are involved in each step.

1) Helicase "unwinds" DNA and separates the two strands from each other.

2) DNA polymerase "reads" the strand and adds complementary nucleotides to the newly created strand.

3) On the lagging strand, DNA ligase connects the fragments together.

A species of fish can differ for two different traits: eye color and stripes. A dominant fish has black eyes; a recessive one has green eyes. A dominant fish has stripes; a recessive fish has no stripes.

A fish heterozygous dominant for black eyes and with no stripes is crossed with a fish heterozygous dominant for black eyes and heterozygous dominant for stripes. Their offspring's phenotypes are:

What is 6/16 no stripes; what is 1/16 green eyes?

Steps of the water cycle are:

What is:

Ground water goes into bodies of water and become run off

Transpiration occurs where plants release water

Precipitation happens and water is released from the atmosphere

Evaporation happens and water evaporates from the surface
