(1) How many bases (base pairs) are their in the human genome? there are at least 3 billion base pairs

(2) How long did it take to determine the identity and sequence of all of the bases? about 13 years

(3) What as the primary source of DNA? and why? semen and sperm, because it has such a high concentration of dna

(4) What is a SNP? single nucleotyde polymorphus

(5) How many genes in the human genome? about 25,000 different genes

(6) What can we learn if we compare the genomes of species? humans share alot of the same chromosomes with similar species

(7) How similar is the human genome to the chimpanzee genome? the genes responsible for hearing and smelling are quite similar

(8) How similar is the human genome to the mouse genome? about 88% similar

Genetic Engineering (p460-463)

(9) Define: transgenic organism-a foreign gene

(10) Describe how we can use transgenic bacteria. to fix bio logical hazards, such as oil spills

(11) Describe how we can use transgenic plants. to promote plant growth and fix plant diseases

(12) Describe how we cna use transgenic animals. the fix certain gene mutations
