DNA/Mutation
What is the name of the mutation of a single nucleotide base?
What is SNPs (Single Nucleotide Polymorphisms)
What is a true bred?
What is individuals with homozygous alleles on every gene loci
What is the shortest phase in a cell cycle?
When is the Mitosis phase
Which part of the DNA is separated during Meiosis I?
What is the homologous chromosomes
What attatch to the enhancers and help bind the RNA-polymerase to the promotor to start transcription?
What are transcription factors
What is a trihybrid?
What is an individual with heterozygous alleles on each of the three different genes
When does the number of "n" doubles in mitosis?
During anaphase in Mitosis
Which part of the DNA is separated during meiosis II?
What is sister chromatids
What kind of mutation has likely resulted in one incorrect amino acid in the protein?
What is missense mutation
If parent 1 is aaBb and parent 2 is AaBb, what is the chance of the offspring having the genotype Aabb?
What is 1/8
When does the number of "c" double in a cell cycle?
When is S phase
How many possible different gametes result from the independent assortment in Meiosis I for humans? (ignore recombination)
What is 2^23 = 8,388,608 different gametes
What part of the DNA is the mutation likely located if the gene expression levels suddenly decrease drastically
What can be either the promotor or the enhancer
If parent 1 is aaBbCCDdeeFfGG and parent 2 is AaBbccDdEEffGg, what is the chance of the offspring having the genotype AabbCcDDEeFfGg?
What is (1/2)^7 = 1/128
(1. check that the offspring genotype is probable
2. count the total number of heterozygous pairs across 2 parents, then take 1/2 to that power)
When is the number of c and n halved?
What is in telophase of mitosis
If the gamete has 2 identical copies per pair of homologous chromosome, what non-disjunction happened?
What is non-disjunction II
What are forward and reverse genetic screens?
A forward genetic screen is an approach used to identify genes (or set of genes) responsible for a particular phenotype of an organism.
A reverse genetic screen, on the other hand, analyzes the phenotype of an organism following the disruption of a known gene.
Danny the frog is spotted and green. Job the frog is unicolored and green. Their offspring Joel is spotted and red. Assuming that green and spotted are the wildtypes, what is the genotype of Job?
What is n for an diploid organism that has 36 individual chromosomes in total?
n = 36/2 = 18
If the gamete has one copy from each parent per homologous chromosome, what non-disjunction happened?
What is non-disjunction I
