genes - ANSWER is a section of a chromosome, provide directions for a cell to
assemble molecules that express traits, ex. eye color, seed color
DNA - ANSWER an organism's genetic material, made up of nucleotides, located on a
chromosome
chromosome - ANSWER made up of proteins and DNA
How do so many directions fit on a few chromosomes? - ANSWER The DNA strands
that the directions are contained in are coiled tightly like a telephone wire
Shape of DNA - ANSWER Double helix, is like a twisted zipper or ladder, discovered by
Rosalind Franklin and Maurice Wilkins using X-rays
Nucleotide - ANSWER A molecule made of a nitrogen base, a sugar, and a phosphate
group
nucleotides in DNA - ANSWER the sugar-phosphate groups form sides of zipper, and
nitrogen bases bond and form teeth of zipper
4 Nitrogen Bases - ANSWER Adenine (A), thymine (T), cytosine (C), and guanine (G)
