E153 final Exam Questions With Complete Solutions
a genetic fingerprint can be generated very fast, str profiling also
be done by PCR using primers flourscently tagged followed
bycapillary electrophoresis Correct Answers
change in total gene represent net balence between gain via gene
duplication and gene loss and hence true rate of gene gain in
evolution must be greater than suggested by raw numbers alone
Correct Answers
Chromosomal banding patterns reflect gene density
dark bands are?
faint bands are? Correct Answers dark bands are gene depleted,
faint bands are gene enriched
Chromosomal regions with high gene density values also feature
high gc content and correspond to faint bands upon Giemsa
staining Correct Answers
classes of transposable elements
transposons, mobile elements or genome wide or interspred or
complex repeats, diversity of dna segments tht can in a process
called transposition, move duplicate from one location in
genome to other Correct Answers
coding component of genome represents small portion in
eukaryotic genomes, 47% of genome is diffrent types of repeats
Correct Answers
, combined used of several vntr result into unique genetic profile
Correct Answers
diffrences in genome size among eukaryotes is due to longer
genes and particulary extra noncoding dna than diffrences in
number of genes, genome size depends on strenght of diffrent
processes with opoosed effects Correct Answers
dna transposons common in prokaryotes but not much in
eukaryotes Correct Answers
duplication of genetic materials occur at diffrent states Correct
Answers
duplication of individual genes Correct Answers
during evolutionary process some sequnces have proliferated
leading to generation of thousands of copies and after that they
accumlate mutation,many cant transpose currently Correct
Answers
gene density correlated with gc content, gc content varies across
genome, isochore model of genome orginization is Correct
Answers mostly vertrbates genomes can be envisoned by a
mosiac of alternating pieces called isochores display diffrent
levels of gc content and gene density
gene duplication Correct Answers individual genes
chromsomal segments
whole genome
