Chromosome transmission during cell division and sexual reproduction
Chromosomes and Cellular Reproduction
Most sexually reproducing organisms are diploid (2n); some simple organisms spend
most of their time as haploids (e.g. fungi, mos
GENE EXPRESSION IN PROKARYOTES
Control of gene expression is at the level of transcription. If a gene is not transcribed then the
gene product and ultimately the phenotype will not be expressed. We are now going to consider
two systems of control of gene

RNA polymerase II (the polymerase that transcribes eukaryotic mRNAs) cannot bind to a
promoter by itself. Rather, it requires other protein factors that are added in a specific order to

Living systems have perfected genetics of inheritance. This is achieved
by variety of natural process that leads to natural selection and speciation,
thus the genetic system of an organisms is inherited and perpetuated for
