The shape of the DNA molecule resembles a twisted ladder and is
described by this name.
What is a double helix? 5
These are the correct base pairs found on the DNA
molecule.
What is adenine and thymine: and
cytosine and guanine?10
Each repeating nucleotide of DNA contains these three elements.
15What is a sugar, a
phosphate group and a nitrogen base?
A strand of DNA formed by the splicing of DNA from two different species is
known as this.
What is recombinant DNA?
20
The two strands of the double helix are held together by these bonds.
25What are
hydrogen bonds?
This group of Pacific Islands proved to be very influential to Darwin’s
theories.
5What are the Galapagos
Islands?
The process by which organisms with traits best suited to their
environment are more likely to survive and reproduce is known as
this.
What is Natural Selection?
10
The human appendix is an example of this.
What is a vestigial structure?
15
The relationship between a honey bee and a dandelion is an example
of this type of evolution.
What is coevolution?
20
The human arm, a dolphin’s flipper and a bird’s wing are examples of
this.
What are homologous structures?
25
This is the science of classifying living things.
5What is taxonomy?
This man developed the system of binomial nomenclature.
Who is Carolus Linnaeus?
10
This language is most commonly used in the
classification of living things.
What is Latin?
15
This is the correct order of biological hierarchy from
largest to smallest.
What is Domain, kingdom, phylum, class, order, family,
genus and species?
20
The scientific name of a organism consists of these
two parts.
What are the genus and species?
25
What are prokaryotic cells?
5
Bacteria are the only examples of this type of cell: without a nucleus.
What are flagella?
10
These are tail-like structures used by some bacteria for movement.
What is one?
15
A typical bacteria cell has this many chromosomes.
This is the name given to any disease-causing agent.
What is a pathogen?
20
Gram positive bacteria will stain this color.
What is purple?
25

5
A virus consists of a piece of nucleic acid surrounded
by this.
Viruses that infect bacteria cells are known as this.
What are bacteriophages?
10
HIV is a virus that shuts down this body system.
What is the immune system?
15
Retroviruses use this enzyme to cause their host cells to
transcribe DNA from an RNA template.
What is reverse transcriptase?
20
This is the viral cycle in which viral dna “hides” in the host cell’s dna
before becoming active.
What is lysogenic?
