What do some viruses store their genome in instead of DNA?
functional non-coding RNAs
What are some gene products?
any discrete locus of heritable, genomic sequence which affect an organism's traits by being expressed as a functional product
What is a broad, modern working definition of a gene?
Gregor Mendel (1822–1884)
Who first suggested the existence of discrete inheritable units?
n is the number of differing characteristics in the original peas
If a distinct trait in edible pea plants is mathematically described as a 2n combination, what does n represent?
independent assortment
What is one thing that Gregor Mendel was the first to demonstrate?
the distinction between dominant and recessive traits

In what time span were the theories to integrate molecular genetic with Darwinian evolution developed?
the modern evolutionary synthesis
What are the theories that integrate molecular genetics with Darwinian evolution called?
George C. Williams
Who proposed an evolutionary concept of the gene as a unit of natural selection?
"that which segregates and recombines with appreciable frequency."
What is the definition of the concept of the gene as a unit of natural selection?
Richard Dawkins
Who popularized ideas emphasizing the centrality of genes in evolution?
long strands of DNA (deoxyribonucleic acid)
What do the vast majority of living organisms encode their genes in?
a chain made from four types of nucleotide subunits
What does DNA consist of?
a five-carbon sugar (2'-deoxyribose)
What type of sugar composes part of the DNA molecule?
adenine, cytosine, guanine, and thymine
What are the four bases used in nucleotide subunits?
a phosphate group
Besides the sugar and the four bases, what else does DNA consist of?
phosphate-sugar
What is the backbone of a DNA double helix made of?
adenine
What base pairs with thymine?
cytosine
What base does guanine pair with?
adenine and thymine align form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds
What causes the specificity of base pairing?
The two strands in a double helix must therefore be complementary
Due to the cause of the specificity of base pairing, what must be true of the two strands in a double helix?
the chemical composition of the pentose residues of the bases
What causes the directionality of DNA strands?
an exposed hydroxyl group on the deoxyribose
What is known as the 3' end?
an exposed phosphate group
What is known as the 5' end?
Nucleic acid synthesis
What type of synthesis occurs in the 5'→3' direction?
because new nucleotides are added via a dehydration reaction that uses the exposed 3' hydroxyl as a nucleophile
Why does DNA replication and transcription occur in the 5'→3' direction?
by transcribing the gene into RNA

a second type of nucleic acid that is very similar to DNA
What is RNA?
the base uracil
