FAU BSC 1005 EXAM 2 QUESTIONS
WITH 100% PASSED ANSWERS!!
what is a chromosome? - CORRECT ANSWER-a large, tightly bound piece of DNA
and protein found in the nucleus of cells
what is a genome - CORRECT ANSWER-the complete set of genetic material
encoded within the DNA of an organism
What is the significance of the '23rd pair' of chromosomes in humans? -
CORRECT ANSWER-it determines a person's sex
a boy's Y chromosome will generally NOT be identical to that of his - CORRECT
ANSWER-great-grandfather on mother's side of family
DNA is a type of molecule called a ______. Its smaller parts are called ________. -
CORRECT ANSWER-deoxyribonucleic acid; nucleotides
which of the following base pairs would be found in normal DNA? - CORRECT
ANSWER-A and T
DNA is called a double helix because - CORRECT ANSWER-two DNA strands
twist together
DNA can be visualized as a ladder. Which parts would be the rungs (where you
step) and which would be the stringers (the sides where you hold on)? -
CORRECT ANSWER-The base are rungs, and the phosphate bases are stringers
What are nucleotides - CORRECT ANSWER-molecules that make up the
information contained in DNA
How is the structure of DNA molecule arranged? - CORRECT ANSWER-Each
nucleotides' phosphate group binds to the sugar group of the next nucleotide
What is the 'double helix' when reffering to the structure of DNA? - CORRECT
ANSWER-two strands of linked nucleotides that are twisted around each other
What is the correct pattern of nucleotide base pairing? - CORRECT ANSWER-
adenine-thymine; guanine-cytosine
, What is the complementary base-pairing rule? - CORRECT ANSWER-adenine will
always pair with thymine, and cytosine will always pair with guanine
Find the sequence that would base pair correctly with ATTCGGC - CORRECT
ANSWER-TAAGCCG
DNA replication occurs - CORRECT ANSWER-in the nucleus
What is DNA polymerase - CORRECT ANSWER-an enzyme involved in DNA
replication that binds to DNA and facilitates the formation of a new strand of DNA
What is meant by 'semiconservative' replication - CORRECT ANSWER-Each
newly replicated strand of DNA consists of one original strand and one newly
formed strand
PCR stands for - CORRECT ANSWER-polymerase chain reaction
You start a PCR process with two copies of a DNA molecule. After three cycles of
PCR, how many copies of the DNA will be present? - CORRECT ANSWER-16
Why is heating a first step in PCR amplification of extracted DNA? - CORRECT
ANSWER-it permits hydrogen bonds between DNA strands to dissociate
PCR amplification of DNA is a useful technique when - CORRECT ANSWER-there
is limited sample
There are ____ different amino acids - CORRECT ANSWER-20
Nucleotides are composed of - CORRECT ANSWER-Sugar, phosphate and a base
An example of a nucleic acid is - CORRECT ANSWER-DNA
DNA differs from RNA because - CORRECT ANSWER-RNA is only one linear
chain, whereas DNA consists of two chains bonded together
Ribosomes are necessary for - CORRECT ANSWER-protein production
proteins are made - CORRECT ANSWER-by the ribosomes
Which of the following shows the steps of PCR amplification in the correct order?
- CORRECT ANSWER-extract DNA, add nucleotides and polymerase, cycles of
heating and cooling
STRs are - CORRECT ANSWER-short tandem repeats
