My Genes made me do it! Consider the Genetic Influences on Criminal Behaviour.
A gene is a sequence on DNA that has a specific region on the chromosome, which determines a particular characteristic in an organism. For many years it has been thought that there are specific genes responsible for certain behaviour and so there is a gene for criminal behaviour. In the first half of the twentieth...

If genes don’t produce the right protein or don’t produce it correctly a person can have a genetic disorder.
Gene therapy is an experimental technique that involves the transfer of a working copy of a gene into a cell to repair or replace a faulty gene so it is able to produce functioning proteins again.
There are several approaches.
The most common one is to insert a normal gene to replace the non-functional gene.
Another approach is to swap a...

Gene Mutations. - 378 Words
A gene is a long sequence of nucleotides on a DNA molecule. A mutation is a change in the amount of an organism's genetic material and when a change in genotype produces a change in phenotype, the individual affected is said to be a mutant. A gene mutation involves a change in one or more of the nucleotides in a strand of DNA. The sequence of nucleotides in a gene controls the order in which amino acids are made into a protein, therefore if the sequence of nucleotides in a gene is altered by a...

If the chicken farmer wants to get larger and more eggs from her chicken, I think she should choose Brian and Fern. If you consider the egg size, because Fern lays medium eggs and Brian lays large eggs, the size of the new eggs will be at least medium or big size. The reason I chose Fern over Marjory even though Marjory lays large eggs because Marjory only lays 5 eggs per week and my target is to have a flock of chickens, which lay a high number of large eggs, therefore I need to carefully...

Rho Independent and Dependent Factors
What is the biological significance of having two different types of terminators in transcription?
Transcription in prokaryotes is terminated by factors called rho-dependent and rho-independent terminators; Rho is a ring-shaped protein and is the main factor required for termination (Leland, 2010). The rho-dependent and rho-independent terminators play a major role in the separation of an RNA transcript from the DNA template which signifies the end of transcription. However, the exact process...

Each human in the world is created both separate and unique. Although members of a family may possess common traits, each member has their own individuality. Genetics allows for a creation of a unique individual. Chromosomes, meiosis, and fertilization are essential parts of genetics vital to the development of a distinct organism. The effect of each allows for a world in which no human is equal.

The Sperm and the Egg
The miracle of life is at the same time amazingly complex and alarmingly simple. It all starts with the act of love. During intercourse, a man can ejaculate up to 500 million sperm inside a woman’s vagina. Each sperm carries the father’s genetic code (or DNA). A man’s testes are constantly at work, churning out over 1000 sperm every second (Rathus, 2011). The quality of the sperm depends on the man’s age, lifestyle, his diet, and more.

Genetic Engineering is the changing of an organism's genetic, or hereditary, makeup to get rid of unwanted characteristics or to make wanted new ones. Genetic engineering is used to increase plant and animal food production. It is also used to help dispose of industrial wastes, to diagnose disease, improve medical treatment, and produce vaccines and other useful drugs. Genetic engineering techniques include the selective breeding of plants and animals, and hybridization, which is the...

River Out of Eden
River out of Eden is a book that focuses on Charles Darwin's theory of evolution. It's author, Richard Dawkins has also written other books on evolution such as The Selfish Gene, The Blind Watchmaker, and The Extended Phenotype. In the book River Out of Eden, Dawkins relates life to being a river of genes that flows through time and how genes use organisms as temporary bodies to live in. So even when an organism dies, the genes live on through the offspring.

Mendelian Inheritance in Drosophila
Lab Report 1
In this experiment we are investigating the strength of the ratios discovered by Gregor Mendel in both the monohybrid and dihybrid cross. The ability to test these ratios stems from the use of Mendel’s law of segregation which states that during meiosis allele pairs will separate in gametes so one of each allele is present in a gamete. (Garey, et al,pg 8-13) These single alleles are then combined with the other parental gamete...
