SAWEY: CONTEMPORARY
ISSUES IN BIOLOGY + LAB
EXAM 1
-by 2017 many thousands of mamals have been reproduced in two
dozen species
-but the clones aren't exactly like the __________ - ANSWERS-
parents
-one goal of cloning is to be able to change animals genetically
quicker than traditional animal breeding methods (that may take
decades to make changes in populations)
-cloning to introduce "no homs" gene into dairy cattle, it eliminates
the need for painful process of dehorning
-produces a strain of pigs that can be infected by the very contagious
and debilitating PRRS virus or producing cattle that cannot develop
Mad Cow Disease
-gained scientific information/insights for development
-this helps reduce birth defects and infertility - ANSWERS-
advantages of cloning
-reproductive cloning is a very inefficient technique and some animal
embryos cannot develop into healthy individuals and die
-Dolly was the only clone to be born live out of a total of 277 cloned
embryos but scientists have become more efficient
,-10% success rate today
-very low efficiency, combined with safety concerns, presents a
serious obstacle to the application of reproductive cloning
-researchers have observed some adverse health effecs in sheep and
other mammals that have been cloned
-one of these is the increase in size at birth aka "large offspring
syndrome - ANSWERS-drawbacks of cloning
-type of human cloning
-could be used to produce embryos with stem cells that could be used
to treat diseases such as Parkinson's Disease and diabetes
-cells would be a perfect genetic match for the person donating the
cells - ANSWERS-therapeutic cloning
-type of human cloning
-will be used to produce embryos that will be implanted into a
woman's uterus and allowed to develop into an infant - ANSWERS-
reproductive cloning
-a cloned child would be the genetically identical twin of the parental
clone but have a different personality
-this is because personality emerges from nature vs nurture (DNA and
the environment in which the fetus and child are raised) - ANSWERS-
biological problems with cloning
-have humans been cloned yet? - ANSWERS-no
,-because of the unacceptable high risks of miscarriages and birth
defects associated with cloning
-not possible to make human reproductive cloning safe - ANSWERS-
U.S. House of Representatives vote in 2001 to ban human cloning
-if it starts with an "H" - ANSWERS-virus
-if it doesn't start with an "H" (HIV, Hep B, Hep C, HPV, Herpes) -
ANSWERS-bacteria
-chlamydia is bacteria (t/f) - ANSWERS-true
-herpes can be cured by antibiotics (t/f) - ANSWERS-false
-syphillis is a virus (t/f) - ANSWERS-false
-you can't get an sti if you've only had one partner (t/f) - ANSWERS-
false
-hpv can increase risk of cervical cancer (t/f) - ANSWERS-true
-thalidomide was used to treat morning sickness (t/f) - ANSWERS-
true
, -in us thalidomide caused seal limbs (t/f) - ANSWERS-false
-shouldn't take vitamins with folic acid (t/f) - ANSWERS-false
-safe to smoke 5x a week when pregnant (t/f) - ANSWERS-false
-if you're healthy pregnant you can wait to see the doctor til the 2nd
trimester (t/f) - ANSWERS-false
-_____ are caused by
-viruses
-bacteria
-other organisms such as protozoans or body lice - ANSWERS-STI's
-infections caused by _________
-gonorrehea
-syphilis
-chlamydia - ANSWERS-bacteria
-how to treat a virus - ANSWERS-treat symptoms only
-how to treat bacteria - ANSWERS-antibiotics
-two parts of breast milk - ANSWERS-foremilk, hindmilk
