DNA is one of these--a large molecule made up of many smaller parts called monomers.
What is a macromolecule or polymer?
100
The information in the DNA molecule is used by your cells to build this other type of macromolecule, which is made of amino acids:
What is protein?
100
This term refers to the different versions of a gene
What are alleles?
100
When two alleles blend together to create a third trait rather than one being dominant.
What is incomplete dominance?
100
Meiosis produces these types of cells:
What gametes?
200
This is the building block, or monomer, of DNA.
What is a nucleotide?
200
The first step in protein synthesis, takes place in the nucleus.
What is transcription?
200
Mendel discovered that one allele is usually this, meaning it will hide or mask the other allele.
What is dominant?
200
When two traits both show up in an organism, but they do not blend together.
What is codominance?
200
During prophase of meiosis, these two event occur that increase the genetic diversity of an organism
What are synapsis and crossing over?
300
Each nucleotide consists of a sugar, a phosphate group, and this important part that actually contains the code
What is a nitrogenous base?
300
Transcribe this gene: GAT
What is CUA?
300
An organism that has two of the same alleles for a particular trait is said to be
What is homozygous?
300
In roses, color is incompletely dominant. What are the possible phenotypes for the offspring in a cross between two pink roses?
What is 25% red, 50% pink, and 25% white
300
During this event, portions of DNA are exchanged between homologous chromosomes
What is crossing over?
400
These are the base-pairing rules for DNA
What is A always pairs with T and C always pairs with G?
400
Translation occurs at this location in the cell
What is a ribosome?
400
This percent of the offspring will show the recessive phenotype when two heterozygous individuals are crossed together
What is 25%?
400
In dogs, fur color is codominant. What will the offspring look like in a cross between a black dog and a white dog?
What is black and white spotted?
400
At which stage in the process of meiosis does the diploid cell become two haploid cells?
What is after anaphase 1
500
DNA replicates, or makes a copy of itself, during this specific part of the cell's life cycle:
What is the S phase of Interphase?
500
These three RNA codons would signify the end of a gene:
What are UAA, UAG, and UGA?
500
A homozygous dominant individual is crossed with a homozygous recessive. What percentage of the offspring will show the dominant phenotype?
What is 100%?
500
In dogs, pointed ears (P) are dominant to round ears (p), and tail length is incompletely dominant (TT= long, Tt= medium, tt= short). What are all possible phenotypes for the offspring of a cross between two dogs that are both heterozygous for both traits?
What is 6 pointed medium, 3 pointed long, 3 pointed short, 2 round medium, 1 round short, 1 round long.
500
In the second division of meiosis, these get pulled apart into opposite cells
What are sister chromatids?
