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 some examples of single-gene diseases? - ANSWER--Cystic Fibrosis,
Hemophilia, Albinism, Huntingtons disease
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 is gene therapy? - ANSWER--The treatment of single-cell disease by
replacing the mutant gene.
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 zygote period? - ANSWER--The is during the first 2
weeks of pregnancy and is when the zygote travels from the Fallopian tube to
the uterus and implants itself in the uterine wall, here is where the amnion
forms. Near the end of the 2 weeks the placenta is developed.
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 happens during the fetal period? - ANSWER--This is during the 9th week
to birth. During this period, organs, muscles, and the nervous system begins to
organize. Lungs begin to expand and contract to simulate breathing. External
genitals are distinguishable. Fingernails, toenails, and eyelids form. After 18
weeks babies movement can be felt by the mother. After 20 weeks baby can
hear and react to sound. After 24 weeks brain neurons are developed. After
25-38 weeks the cerebral cortex continues to develop and fetus gains a layer of
fat, ultimately adding 5 pounds to the babies weight. The fetus receives
antibodies from the mothers blood to protect it from illness until its own
immune system forms.
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
Why should a mother consult a doctor after taking any medication? - ANSWER--
Some medications can cause low birth weight, low intelligence, and death.
What is Fetal alcohol syndrome? - ANSWER--This is a serious effect due to a
mother consuming alcohol during pregnancy. This can cause mental
retardation, poor attention, and hyperactivity.
What are some non-teratogenic health concerns? - ANSWER--Nutrition, anxiety,
miscarriage, chromosomal defects, medical care, mothers age, good
incompatibility
What is considered the neonatal period? - ANSWER--The first 4 weeks of life
What does the apgar scale measure? - ANSWER--Appearance, Pulse, Gimace,
Activity, and respiration
What is the purpose of bonding? - ANSWER--With a bond, newborns feel safe
and secure. This allows them to develop with confidence.
What are some newborn reflexes? - ANSWER--Rooting reflex: When newborns
cheek is stroked they turn toward the simulation, Sucking reflex: When finger
