THE MOLECULAR BASIS OF INHERITANCE I. History A. Discovery of “transformation” – a change in genotype and phenotype due to the uptake of external DNA by a cell 1. Griffith 1920s did experiments with Streptococcus pneumoniae (p294 fig16.2) a. took two strains of S. pneumoniae‚ one virulent‚ one not b. heat killed virulent strain‚ then mixed them with the living nonvirulent strain c. living nonvirulent strain became virulent d. nonvirulent strain took on virulent strain’s DNA became virulent

In studying the evolution of human behavior there are many different approaches‚ learned in Fuentes book. These four major approaches focus on natural selection. These approaches are‚ Human Behavioral Ecology‚ Evolutionary Psychology‚ Dual Inheritance Theory‚ and Memetics. Human Behavioral Ecology is the study of behavior from ecological and evolutionary perspectives with the goal of linking ecological factors and adaptive behavior. (Krebs and Davies 1997). Evolutionary Psychology is understanding

Practical 12: Digestion in Humans Aim: To distinguish between 5 liquids to come to a conclusion from which region of the alimentary canal it was extracted from. Hypothesis In this practical‚ we have been given 5 unknown solutions hence it is not possible for us without any logical analysis to come up with a conclusion regarding the positioning along the alimentary canal. We cannot come up with a proper answer or predict results without running through the tests. I though can base my

It is always funny when you hear someone say your child looks more like you than your spouse or vice versa. While they always are saying things like that‚ it is interesting to see if they are really thinking about why they are saying that. What traits have been carried onto a child to make them resemble one parent more than the other or maybe a grandfather or grandmother? What controls the traits that a person exhibits and the traits that are hidden deep down‚ sometimes for generations at a time

The purpose of this experiment was to observe the process of human evolution by observing similar features of the Pan troglodytes‚ Australopithecus afarensis‚ Homo erectus‚ Gorilla gorilla‚ Australopithecus boisei and the‚ Homo neanderthalensis in comparison to those of the Homo sapien. According to Darwinism‚ the species that had the most traits in common with the Homo sapien must be the most related while species with the least traits in common with the Homo sapien were the least similar.

Inheritance by Hannie Rayson is a play about the war between two families‚ the Delaneys and the Hamiltons‚ over property. Rayson questions the authenticity of Australian values‚ due to the human weaknesses the characters present in the play. The Australian values Rayson challenges in this play include a fair go for all and strong family ties. In this play‚ not every character is entitled to equal chances. Nugget is an example of this. He is the bastard son of Farley Hamilton‚ and an aborigine. His

and the gene may not function correctly or at all ("Trinucleotide repeats: fragile-x‚" 2008). Huntington’s Disease (HD) is an autosomal dominant pattern of inheritance. Males and females are equally likely to inherit the mutant gene. The change in the gene takes place when the gene is passed from parent to child. Nontraditional inheritance plays a role in the development of HD when symptoms appear at an earlier age with each generation. The mutant genes repeat more times than the usual number in
