day 2
day 45
day 21***
day 100
Question 2
3 / 3 pts
The replication of the DNA. involves one double-stranded DNA unwinding into two strands
which become part of the new “daughter” double DNA strands. Because the new strands have
one new and one old strand this is called;
semi-conservative replication***
non-conservative replication
extra-conservative replication
faulty-conservative replication
Question 3
3 / 3 pts
The DNA polymerase is like a sewing machine adding new nucleotides to a growing chain of
nucleotides as it “reads” the genetic code.
True***
False
Question 4
3 / 3 pts
The Bible does not mention conception at all.
True
False***
Question 5
3 / 3 pts
Which of the following is true about human chromosomes?
They are present in humans as pairs, with each pair having a unique structure***
The location of the centromere often helps to determine the shape of the individual
chromosomes***
Chromosome pairs in an individual human are constructed of chromosomes only from the
mother
Chromosome pairs in an individual human are constructed of chromosomes only from the father
Question 6
3 / 3 pts
This scientist generated x-ray data of the DNA molecule which helped determine its double helix
structure;
Rosalind Franklin***
Francis Watson
James Crick
Bill Clinton
Question 7
3 / 3 pts
Gender is determined genetically at conception because;
this is when the egg and sperm unite and all the chromosomes are in place including the X and Y
chromosomes to make a new individual***
the chromosomes segregate and do not reunite during the formation of the new individual
the chromosomes are replicated into four copies and reunited into four pairs
the overall number of paired chromosomes decrease.
I Question 8
0 / 3 pts

True*** Correct answer
False
P Question 9
2.25 / 3 pts

God recognizes persons in the womb***
Question 10
3 / 3 pts
The histone code;
involves histone proteins which the DNA. is wrapped around***
involves histone nucleotides wrapped around carbohydrates
involves histone carbohydrates wrapped around RNA.
involves histone proteins wrapped around membranes
P Question 11
2.25 / 3 pts
Which of the following is true about the eugenics movements of the last century

involved medical experimentation on jews and others during World War II***
Question 12
3 / 3 pts
Which of the following is true about aneuploidy?
Is often lethal to pre-born children***
Human babies who survive aneuploidy often have 3 of the same chromosome type rather than 2
chromosomes of the same type***
Trisomy 21 or Down’s Syndrome is the most common form of aneuploidy with many children
living a full life span***
Occurs in most all babies who are born
Question 13
3 / 3 pts

chromosomes?
karyotype
meiosis***
mitosis
halitosis
Question 15
3 / 3 pts
The Sanctity of life shows that man possesses it to a higher level than animals but all living
things possess some of level of sanctity because God’s declared his creation to be “good.”

Jacobs syndrome***
A.lzheimer’s
Trisomy 21
Down’s syndrome
I Question 17
0 / 3 pts
