PCB 3063 Genetics Exam 1 Latest 2025 100%
Accurate Spring (Complete) FAU
Genetic Transmission
transmission of genetic material between parental and daughter cells
(must be precise)
Genetic transmission in prokaryotes
-Lack of nuclear envelope and membrane bound organelles
-nucleoid (bacterial chromosome)
-circular
-attached to cell membrane
-DNA replicates and splits to daughter cells
Genetic transmission eukaryotes
membrane bound organelles, chromosomes in nucleus, and the centrioles
are important
Centrioles
Component of centrosomes, involved in organizing spindle fibers
,Spindle
a microtubule structure that attaches to the kinetochore, directs the
chromosomes to opposite poles
Mitosis
production of two daughter cells with the same number of chromosomes
as parents cell (2n);
multicellular organisms begin life as a fertilized egg (zygote).
Somatic cell division
all cells contain the same number of chromosomes
Karyotype
matches up homologous chromosomes
, X & Y exception
x and y chromosomes are not in a homologous pair, this is an exception
Locus
position of a gene
Alleles
different forms of a gene
Formation of gametes
the exception of mitosis because they do not form through mitosis
Interphase
chromosomes uncoiled as chromatin
Prophase
