Questions with Answers
less than needed for x - Answer-Suppose that the dan from bacterial species y was
shown to contain 15% guanine relative to the dan for species x. the amount of energy
necessary to completely dissociate species y dan into tow sing strands would be:
d - Answer-Polytene chromosomes: -contain chromosome arms that can be
distinguished without specializing g banding b- contains hundreds of replicated dan
strands c- contain heterochroamin that may be under replicated relative to euchromatin
d) all of the above
no barr bodies - Answer-turners syndrom
true - Answer-heterozygosity for an inversion of chromosome will result in a reduction in
recombination frequency for genes located in the vicinity of the inversion
false - Answer-The first indication that the bacterial chromosome was a circle was
obtained from autoradiography studies by john cairns
numbers go same way, flip letters and the change into other - Answer-the base
sequence
true - Answer-The template dan strand indicated at 1 in the figure has a 5 to 3 polarity
running in the clockwise direction
2( the one in the middle) - Answer-The origin of replication for this chromosome is best
represented at site
topoisomerase - Answer-An enzyme needed to resolve the overwinding in the dan
occurring at site 4 is:
1 peak - Answer-After the first replication cycle
involved in the control of the cell cycle - Answer-Which of the following statements
concerning bilateral rentblastoma
x chromosome monosomy - Answer-which of the following human karyotypes has the
mildest phenotypic consequences in infants
all of the above - Answer-polytene

, all of the above - Answer-bilateral retinoblastoma is/ are true
false - Answer-true or false the first indication that the bacterial chromosome was a
circle was obtained from the autoradiography studies of john cairns
30% - Answer-Suppose that the DNA from bacterial species x was shown to contain
20% guanine the amount of adenine found in the dan would be
more than needed for x - Answer-Suppose that the DNA from bacterial species Y was
shown to contain 25% guanine relative to the dan for species x, the amount of energy
necessary to dissociate species y dan into two single strands would be:
true - Answer-In these mapping experiments genetic material was transferred through a
bacteriophage
SAYWR - Answer-The relative order of the genes int the bacterial chromosome is
W and R - Answer-Which of the following appear to be most closely linked on the
bacterial chromosome
1 - Answer-A bacteriophage absorbs to a host bacteria in a liquid growth medium,
before lysis the infected coil is added to a suspension of cells and then plated on an
agar plate to form a lawn how many plaques are expected to result from this infection
event
c provided a hint to watson and crick that dan might be self complementary - Answer-
char gaffs rule
i- the ran molecule that is part of this enzyme is used as a template - Answer-
telemorase
