1

Adenine

one of the four bases that combine with sugar and phosphate to form a
nucleotide subunit of DNA; adenine pairs with thymine.

2

Amino Acids

organic compound that is the chief component of protein (proteins are
made of amino acids).

3

Anticodon

a three nucleotide sequence of tRNA that is complimentary to an mRNA
codon.

4

Codon

a three nucleotide sequence of mRNA that is complimentary to a tRNA anticodon and DNA triplet.

5

Complementary Nucleotide Pairs

nitrogenous base pairing; A-T, T-A, G-C, C-G.

6

Cytosine

one of the four bases that combine with sugar and phosphate to form a
nucleotide subunit of DNA; cytosine pairs with guanine.

7

DNA (deoxyribonucleic acid)

one of two forms of nucleic acid, records instructions for
cellular activity and transmits them from generation to generation; the “blueprint of life”.

8

DNA Helicase

enzyme that unwinds the DNA’s double helix during DNA replication.

9

DNA Polymerase

enzymes that add nucleotides that pair with each base to form new
double helix strands.

10

Double Helix

twisted ladder formation of DNA.

11

Erwin Chargaff

discovered that adenine always pairs with thymine and cytosine
always pairs with guanine.

12

Francis Crick

with James Watson, was the first to develop an accurate model of DNA.

13

Gene Expression

the manifestation of the genetic material in the form of specific traits.

14

Genetic Code

sequence of DNA nucleotides in the nucleus of eukaryotic cells.

15

Guanine

one of the four bases that combine with sugar and phosphate to form a
nucleotide subunit of DNA; cytosine pairs with guanine.

16

Heredity

the qualities derived from one's ancestors.

17

James Watson

with Francis Crick, was the first to develop an accurate model of DNA.

18

Maurice Wilkins

worked with Rosalind Franklin to develop the x-ray diffraction
images of the DNA molecule.

19

mRNA (messenger RNA)

the molecule that carries the DNA code from the nucleus to
the cytoplasm.

20

Nucleotide

basic unit of DNA and RNA, consisting of a nitrogenous base, a sugar and a phosphate.

21

Purine

a nitrogenous base in DNA that has a double-ring structure; one of the two categories of DNA bases: either adenine or guanine.

22

Pyrimidine

a nitrogenous base in DNA that has a single-ring structure; one of the two categories of DNA bases: either thymine or cytosine.

23

Replication

the exact copying of the DNA molecule.

24

Ribosome

in a cell, a tiny knob-like organelle where protein is manufactured; site of
protein synthesis.

25

Rosalind Franklin

developed high quality x-ray diffraction images of a DNA molecule;
this evidence suggested that DNA was a helix shape with 2-3 strands.

26

Template

a model for base pairing used to form proteins.

27

Thymine

one of the four bases that combine with sugar and phosphate to form a
nucleotide subunit of DNA; cytosine pairs with guanine.

28

Transcription

process in which DNA’s code is converted to complimentary mRNA code.

29

Translation

part of protein synthesis that takes place at the ribosome and uses the
codons in the mRNA molecules to specify the sequence of amino acids in a protein.

30

tRNA (transfer RNA)

an RNA molecule that brings amino acids to the growing end of a
polypeptide protein chain during translation.

31

Uracil

one of the four bases that combine with sugar and phosphate to form a
nucleotide subunit of RNA; uracil pairs with adenine.
