The Ultimate Genetics Notes

Simple explanation for what Trinucleotide Repeat Diseases are and the two most important diseases to know for this course

Highlights seperation of homologous chromosomes, sister chromatid seperation, chromosomes and chromatids in each step, and outcomes of meiosis I and meiosis II.

Basic information to know about the trp operon, an inducible operon when trp levels are low.

Overview of the Mechanisms of Evolution.

Diagrams of eight different pedigrees, with key differences that help students to determine the mode of inheritance (autosomal or x linked) (dominant or recessive).

Defines and explains epigenetics, the way in which chromatin structure influences gene expression, and mechanisms for controlling chromatin structure to influence what genes are expressed.

Key differences between eukaryotic and prokaryotic gene regulation and the use of chromatin remodeling to affect gene expression in eukaryotes.

Another overview of the lac operon in bacteria. Key terms to know. The lac operon is an inducible operon that turns on in the presence of lactose.

Complete summary of DNA replication, includes the semiconservative model (vs conservative and dispersive), comparison between prokaryotic and eukaryotic replication, and definitions of the key actors.

Main actors including the repressor, operator, promoter, cap site, and x,y,z genes.

Demonstrates how nondisjunction occurs in Meiosis I and Meiosis II and how that determines how extreme the inherited disease is.

Summarizes differences between continuous and discontinuous traits, meristatic and threshold traits.

A simplified drawing of translation with the main points highlighted and the differentiation between eukaryotic and prokaryotic translation.

Population Genetics can be a difficult chapter in genetics. This summary provides key terms to know as well as key equations to use when solving.
