Unit 6 Section 1
True or False: RNA is double stranded
False
Name the sequence of the central dogma
DNA to mRNA to Protein via transcription and translation
The nucleotide in mRNA but not DNA
Uracil
True or False: A population with high genetic variation is more likely to go extinct than a population with little genetic variation
False
Name 2 pieces of evidence for evolution
Fossils, Anatomy/Embryology, Biogeography, Molecular Biology, Direct Observations
A complete set of genes or genetic material present in a cell or organism
A Genome
The strand during DNA replication that is made of sealed Okazaki fragments
The lagging strand
Where does translation occur?
The Ribosome
Dog breeding is an example of this type of selection
Artificial Selection
If AA is .64, what is the frequency of 1 dominant allele?
0.8
Name the three types of RNA
tRNA, mRNA, rRNA
The term for double stranded DNA running in 2 opposite directions
Antiparallel
The part of an mRNA that gets spliced out during alternative splicing
Introns
What genotype is P2
Homozygous Dominant
What genotype is 2pq and q2
Heterozygous and Homozygous Recessive
Name 3 enzymes that work during DNA replication
DNA Polymerase, Helicase, Ligase, Topoisomerase, and Primase
Part of a tRNA that binds to a specific mRNA codon
Anticodon
What is added to the 5' end of mRNA in eukaryotes?
5' GTP Cap
Name the 4 factors of evolution
Natural Selection, Mutation, Genetic Drift, Gene Flow
Name the 5 factors of Hardy-Weinberg
No mutation, Random mating, No Gene Flow, Infinite/Large Population Size, No Selection
Name the 3 different point mutations
Silent, Missense, and Nonsense mutations
What process is the main regulation point for eukaryotic gene expression?
Transcription
What is added to the 3' end of mRNA in eukaryotes?
Poly-A Tail
The Amish are example of this effect
The founder effect
Polyploidy plants are examples of this type of speciation
Sympatric Speciation
