Mendelian Genetics DNA, RNA, and Proteins I DNA, RNA, and Proteins II Evolution I Evolution II
100
What is dominant?
This type of allele is always fully expressed when present.
100
What is DNA?
This double-stranded molecule is the genetic material of all living organisms.
100
What is a nucleotide?
This is called the fundamental unit of DNA.
100
Who is Charles Darwin?
This scientist is credited with the discovery of evolution by natural selection.
100
What is the HMS Beagle?
46. Darwin set sail on his global voyage in 1831, aboard this vessel.
200
What is heterozygous?
This means that an individual's genotype consists of two different alleles.
200
What is Uracil?

[U]
Adenine (A) in DNA base pairs with this RNA nucleotide during transcription.
200
Who are Watson & Crick?
They used Chargaff's & Franklin's data to first build a complete and accurate model of DNA
200
What is the population?

[species]
Evolution doesn't act on the individual. Rather, it acts on this.
300
What is "descent with modification"?
Darwin coined this phrase; essentially describing evolution.
300
What is the Law of Segregation?
This Mendelian Law basically states that for every gene each parent can only give one allele to each offspring.
300
What is transcription?
This process results in an mRNA copy of DNA.
300
What is helicase?
This enzyme unzips the DNA double helix in the 1st step of DNA replication.
300
What is microevolution?
This scale of evolution refers to the change of traits/alleles within a population.
400
What is allopatric speciation?
This type of speciation occurs when populations become geographically separated.
400
Who is Gregor Mendel?
His experiments on pea plant inheritance paved the way for modern genetics
400
What is semi-conservative?
This term refers to the process of DNA replication. It results in two DNA molecules each having one old and one new DNA strand.
400
What is a protein?
This is the result of translation, which is the final process in gene expression.
400
What is natural selection?
This is when the environment selects individuals who will pass their traits to the next generation.
400
What is convergent evolution?
This explains why distantly related species have similar traits. Wings for flight, for example.
500
What is a pedigree?
This is a diagram showing the inheritance of a family trait.
500
What is anti-parallel?
This term refers to the directionality of DNA. Where each single DNA strand is marked by a 3’ end (OH group of Sugar) & a 5’ end (phosphate), and runs counter to the other in every molecule of DNA.
500
What is a phosphate group?
This along with a 5-Carbon sugar and a N-base make up the 3 components of a nucleotide.
500
What is the Modern Synthesis?
This is the unification of Darwin’s theory and Mendelian genetics.
500
What is punctuated equilibrium?
This idea suggests that species remain relatively unchanged for long periods of time and evolve quickly over short periods of time.
