E153 FINAL EXAM QUESTIONS WITH
VERIFIED ANSWERS
\.genes are distributed __________ along the chromosome,some portions of the
eukaryotic chromosome are characterized by very low gene density values -
ANSWERS✔-unevenly
\.Chromosomal banding patterns reflect gene density
dark bands are?
faint bands are? - ANSWERS✔-dark bands are gene depleted, faint bands are gene
enriched
\.gene density correlated with gc content, gc content varies across genome,
isochore model of genome orginization is - ANSWERS✔-mostly vertrbates
genomes can be envisoned by a mosiac of alternating pieces called isochores
display diffrent levels of gc content and gene density
\.giemsa staining
AT rich-
GC rich- - ANSWERS✔-at- dark band
gc- faint bands
, \.Chromosomal regions with high gene density values also feature high gc content
and correspond to faint bands upon Giemsa staining - ANSWERS✔-
\.genome size in prokaryotes is correlated with number of genes but in eukaryotes
the size varies tremendously - ANSWERS✔-
\.genes represent small fraction of genome in some eukaryotic species -
ANSWERS✔-
\.genome size and organismal complexity are poorly connected, c value paradox,
1st aspect lack of precise correlation between organismal complexity and genome
size if proxy used for complexity is genes then its g value paradox, c value amount
of dna in haploid cell - ANSWERS✔-
\.genes represent a small fraction of genome in some eukaryotic species -
ANSWERS✔-
\.coding component of genome represents small portion in eukaryotic genomes,
47% of genome is diffrent types of repeats - ANSWERS✔-
\.less complex organisms have more compact and coding efficent genomes, higher
gene density - ANSWERS✔-
\.genome size in eukaryotes influnced by multiple factors, factors: regulatory
sequnce complexity, number of genes include more copies of genes, whole
