When a target piece of DNA is cut with restriction enzymes, the different sized DNA fragments that result are known as _____. These uniquely sized pieces of DNA can be run through gel electrophoresis chamber to produce a unique "fingerprint" of an individual's DNA.

What is the job of the Taq polymerase enzyme during PCR process?
adds dNTPs to template strands during extension
Cells can be harvested from different areas of the body to produce a karyotype of the genetic information in the cells. What type of cells are being harvested in the image below?
aminocytes
____ is the accumulation of bad fats in the blood vessels of the body that can lead to plaque formations. These accumulations in the blood vessels can restrict blood blood and eventually lead to blockages in the blood vessels.
atherosclerosis
Chromosomes 1-22 in humans that don't determine sex of individual are known as ____.
autosomes
LDL=
bad
ventricle =
bottom of heart
Click all that apply: What are healthy ways to reduce the risk of atherosclerosis?
choose plant oils over animal oils; choose unsaturated fats and oils rather than saturated; stay balanced, eat in moderation, exercise
blood histology
clogged =unhealthy
Heart Image : Colored red are the blood vessels on the surface of the heart that supply blood to the heart muscle itself. What are these vessels? Don't eat too many foods high in saturated fats or you can slowly clog these vessels. :( Don't FOG up you drains with Fats, Oils, and Grease.
coronary arteries
Why is it significant that reproductive gametes contain only half of the genetic code?
each parent contributes half the genetic information making a new cell with a complete set
The etymology (word meaning) of atherosclerosis is ____ .
gruel (oatmeal) hardening
HDL=

A reduction division in which the chromosome number in cells is reduced to half and gametes are produced.
meiosis
What type of fat is pictured below?
monounsaturated fat
Atherosclerosis that results in the coronary arteries can lead to blockages that prevent blood from moving to the heart cardiac tissue which can result in a heart attack. What is another name for a heart attack?

Interpret the gel and click all true statements below. Q40
patient 2 is heterozygous for FH (they have one normal allele and one diseased allele); patient 3 is at risk for high blood cholesterol levels
Which career would take blood and be able to indicate the levels of a patients LDL and HDL levels in the patient's blood?

_______ are used in PCR to localize and target a specific region of DNA to be copied.
primers
Click all that apply to mitosis.
produce identical daughter cells; prophase; ocours in body cells
Click all that apply to chromosomes.
replicated chromosmes consist of two sister chromatids; replicated chromosomes get pulled apart during anaphase of mitosis so that all new cells will have a copy of the genetic code;sister chromatids are connected at a central region known as the centromere;chromosomes are packages of DNA that form during cell division
Click all true statements about the image below.
restriction enzymes are used on the DNA samples before placing the samples into the wells; DNA RFLPs placed in the wells will move fastest through the gel if they are smaller pieces; if a lane has 3 bands, there have usually been two restriction sites on the DNA sample that have been cut with restriction enzymes
Bad fats that should be avoided in greater concentration in one's diet are ____.
saturated fats
A replicated chromosome consists of two replicated identical strands of DNA called _____.
sister chromatids
