Where is mRNA formed?
in the nucleus
Oops!
Okay!
Why are the codons important?
When rRNA 'reads" the mRNA, the codon codes for a specific amino acid
Oops!
Okay!
What is a blastocysts?
a hollow ball of cells that develops after the morula
Oops!
Okay!
In men, urine and semen are carried outside the body through the urethra. T or F
True
Oops!
Okay!
Where does mRNA travel from/to?
It travels from the cell's nucleus to the cytopasm.
Oops!
Okay!
tRNA
contains 3 base pairs (anti-codon), one amino acid

Okay!
Which phase of the menstrual cycle does the oocyte mature into an ovum?
Follicular phase
Oops!
Okay!
What happens in the process of RNA processing? (mature/pre-mRNA)
a cap is added; introns removed; poly-A tail is added.
Oops!
Okay!
What is rRNA
two subunits of a ribosome
Oops!
Okay!
What is semen?
Semen contains fluids, sperm and nurishment
Oops!
Okay!
Where is the anit-codon found?
on tRNA
Oops!
Okay!
What are the female reproductive glands?
ovaries
Oops!
Okay!
Why is the placenta important to a pregnacy?
The placenta allows oxygen, nutrients, drugs and alcohol to be transported to the fetus and removes the waste from the fetus to the mother
Oops!
Okay!
What is the tube that connects the ovary to the uterus
oviduct
Oops!
Okay!
What process triggers the production of testosterone in the testes?
hypothalamus produces GnRH stimulating the pitutary gland to produce FSH & LH which is release in the blood to the testes.
Oops!
Okay!
Where does the baby develop?
uterus
Oops!
Okay!
Which phase of the menstrual cycle does the corpus luteum break down?
Luteal phase
Oops!
Okay!

no protein, stop
Oops!
Okay!
an ovum is ...
a mature egg released by the ovary
Oops!
Okay!
How does testosterone affect boys?
deepens their voice, broad shoulders, increased muscle mass, body hair; sperm production in testes
Oops!
Okay!
Where does fertilization take place?
in the oviduct, near the ovary
Oops!
Okay!
If progesterone and estrogen are high, then FSH and LH are
low
Oops!
Okay!
A morula is -----
a solid ball of embryonic cells that forms before the blastocyst
Oops!
Okay!
What is mRNA?
strands of RNA complementary to DNA
Oops!
Okay!

AUGC
Oops!
Okay!
What test is used to test a fetus's DNA?
amniocentesis
Oops!
Okay!
Whys is the corpus luteum important for pregnancy?
It produces progesterone, which keeps the endometrium from shedding.
Oops!
Okay!
What are codons?
a set of 3 base pairs on mRNA
Oops!
Okay!
GCA codes for which protein?
Ala
Oops!
Okay!
UCA codes for which protein?
Ser
Oops!
Okay!
How does estrogen affect girls?
widen hips, breast formation, egg production in ovaries; menstrual cycle
Oops!
Okay!
What part of the male reproductive system maintains sperm temperature?
scrotum
Oops!
Okay!
Explain why a pregant woman should not consume drugs or alcohol during pregnancy.
Drugs and alcohol will pass through the placenta/umbilical cord to the fetus. It is very harmful to the fetus.
Oops!
Okay!
What is removed from mRNA before it leaves the nucleus?
introns
Oops!
Okay!
If progesterone and estrogen are low, then FSH and LH are
high
Oops!
Okay!
