GCD 3022 Exam 1 Questions With Complete Solutions
30 nm Fiber Correct Answers nucleosomes associate
A-DNA Correct Answers right handed helix, 11 bp per turn,
low humidity, little biological importance
ABO blood groups Correct Answers antigen on surface of red
blood cells, O recessive, A and B codominant- both expressed in
heterozygote, gene encodes enzyme to add sugar to
carbohydrate tree on RBC, O- null allele, recognized by
different antibodies, can agglutinate
acrocentric Correct Answers chromosome centromere closer to
one end
Affected pedigree Correct Answers
Alfred Sturtevant's experiment Correct Answers first genetic
map, undergraduate, 6 mutant alleles, recessive and X-linked ,
further apart- more recombinations
Alleric variations Correct Answers due to mutations in
particular genes
Alternative DNA structures Correct Answers normally B-
DNA, in vitro can be A-DNA, Z- DNA
Anaphase Correct Answers separate chromosomes, connection
broken,
,Anaphase I Correct Answers chromosomes separate
Anaphase II Correct Answers chromatins separtate
Aneuploidy Correct Answers variation of number of one
chromosome in a set- trisomy 2n +1, monosomy 2n-1, messes
with gene products amounts, increases frequency with age of
mother, mostly leathal, some can surive
Angelman syndrome Correct Answers hyperactivity, unusual
seizures, repetitive symmetrical muscle movements, mental
deficiencies, small deletion on chromosome 15, only caused if
inherited from mother
Angiosperm pollination and fertilization Correct Answers
endosperm- provides food for embryo, micropyle- small opening
in
Antibodies Correct Answers proteins produced in immune
system, binds to foreign things, white blood cells eat, early in
development humans make a lot
antigen Correct Answers something that is recognized by
antibodies
Astral microtubule Correct Answers does not connect to
kinetochore
Autosome Correct Answers any chromosome not sex
chromosome
, Bacterial Chromosomes Correct Answers most circular
chromosomal DNA, few million base pairs, single
chromosomes, some bacteria several copies, intergenic regions,
repetitive sequences, compacted- loop domains and super
coiling
Bacterial DNA replication Correct Answers oriC- origin of
Chromosomal replication, bidirectional, replication forks meet
Balding Correct Answers related to amount of testosterone,
over expression gene converts testosterone to DHT- binds to
receptors and alters expression,
Barr body Correct Answers inactivated X chromosome in
female, highly condensed
Bivalent Correct Answers pair of homologous chromosomes
form tetrad with synaptomemal complex
Blending theory inheritance Correct Answers factors that
dictate inheritance blend from generation
Caenorhabditis ( Worms) Correct Answers expression of X in
hermaphrodites is halved
Cell fusion Correct Answers individual cells mixed together,
new strains plants, crossing species that cannot interbreed
naturally, plants- digest cell wall -> protoplasts, treat with agents
to promote cell fusion -> heterokatyon, spontaneous nuclear
fusion -> hybrid cell, grow in laboratory,
