What happens when genes mutate? - ANSWER--They normally become the basis
for some form of disease.
What are single-gene diseases? - ANSWER--This results from an individual
mutant gene and may cause a failure to create something necessary.
What are chromosomal diseases? What are the categories? - ANSWER--This
disease is a result of chromosomal breakage, abnormal chromosome, or a
missing chromosome. They two categories are trisomy and monosomy.
What are examples of nonfatal chromosomal diseases? - ANSWER--Down
syndrome and Turner syndrome
What are genetic engineering and recombinant DNA? - ANSWER--Recombinant
DNA is the imitation and artificial manipulation of DNA. With recombinant
DNA, scientist hope to replace defective genes with copies of healthy genes.
How long does prenatal development last? - ANSWER--38 weeks from
conception to birth

What happens during the embryonic period? - ANSWER--This period is from the
2nd weeks to the 8th week. Three layers of cells develop (1. Ectoderm Layer:
Skin and nervous system, 2. Mesoderm: Muscle, skeleton, cardiovascular
system, and other organs, 3. Endoderm: Digestive system, lungs, urinary tract,
and glands.). Heart begins to pump blood. During the second half of this
period facial features, arms, legs, fingers, and toes begin to form.
What is gene therapy? - ANSWER--The treatment of single-cell disease by
replacing the mutant gene.
What are some examples of single-gene diseases? - ANSWER--Cystic Fibrosis,
Hemophilia, Albinism, Huntingtons disease
What is the age of viability? - ANSWER--When a fetus has a chance to live
outside the womb and survive. Normally from 25-38 weeks.
What are teratogens? What are some examples? - ANSWER--Environmental
substances that may cause damage during prenatal development. Examples:
medications, drugs, alcohol, and pollution
