Mitosis and DNA Replication
In this phase of mitosis, chromosomes split apart and move to opposites ends of the cell.
What is anaphase?
This is the number of cells at the end of meiosis.
What is 4?
This is the term we use to describe a genotype where the alleles are different from each other. Ex: Gg
What is heterozygous?
This man came up with the theory of natural selection.
Who is Charles Darwin?
What is a genus and species?
This is the first step of DNA replication.
What is transcription?
When part of a chromosome is copied twice, we call it a ______________.
What is duplication?
In unicorns, a short horn is recessive to a long horn. What is the genotype of a unicorn with a short horn? Use the letter R.
What is rr?
This is the name we call a trait that gives a survival advantage to an organism.
A node on a phylogenetic tree represents a ___________ _____________.
What is a common ancestor?
This is the type of RNA that takes a message from the nucleus to the ribosome.
What is mRNA?
Meiosis one separates these kinds of chromosomes.
What are homologous chromosomes?
A fish can be red, blue, or red with blue spots. What type of dominance does this fish display?
What is codominance?
This is the term we use to describe when a small group breaks off from a population and establishes a new population elsewhere.
What is the founder effect?
This level of taxonomy comes AFTER Phylum.
What is class?
This is the organelle where transcription takes place.
What is the nucleus?
Crossing over occurs in this step of meiosis.
What is prophase 1?
Have Tay-Sachs disease is recessive. If a woman with Tay-Sachs has a baby with a man who does not have Tay-Sachs (he is homozygous), what is the probability of their child having Tay-Sachs?
What is 0%?
A population of mice can be light, medium, or dark colored. Those that are light can blend in with the sand on the beach while those that are dark can blend in with the igneous rocks. We call this type of selection (directional/disruptive/stabilizing).
Disruptive
Under a microscope, you see a single-celled organism with a cell wall and nucleus. It belongs to this kingdom.
What is protista?
The cells produced at the end of mitosis are ___________ (haploid/diploid) and genetically ___________ (identical/different) from the parent cells.
What are diploid and identical?
This is what we call it when a cell ends up with too many or too few chromosomes.
What is nondisjunction?
This is the phenotypic ratio of a dihybrid cross where both parents are heterozygous for both traits. Ex: GgHh crossed with GgHh.
What is a 9:3:3:1 ratio?
Bacteria can become resistant to antibiotics due to random chance causing a __________ in their DNA, leading them to survive and reproduce.
What is a mutation?
The kingdoms animalia, protista, plantae, and fungi all share this characteristic in common.
What is they are eukaryotes/have a nuclues?
