A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked. Men normally have an X and a Y combination of sex chromosomes‚ while women have two X’s. Since only men inherit Y chromosomes‚ they are the only ones to inherit Y-linked traits. Men and women can get

DIFFERENCES BETWEEN PLASMID AND CHROMOSOMAL DNA IN BACTERIA. Eukaryotes have two or more chromosomes‚ prokaryotes such as bacteria possess a single chromosome composed of double-stranded DNA in a loop. DNA is located in the nucleoid of the cell and is not associated with protein A plasmid is an extra-chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently of the chromosomal DNA. Plasmids usually occur naturally in bacteria. A chromosome

The warrior gene indicates that some individuals are born with the war gene. Henry Rowland was born in Washington D.C. when his parents divorced at an early age. The separation between his parents caused him to develop anxiety. Rowland expresses in the video that he often thinks to himself why he is the way he is always filled

Week 8 Assignment 2: Gene Technology Introduction to Biology Mr. James Cox March 3‚ 2013 Gene technology is the term given to a range of activities concerned with understanding the expression of genes‚ taking advantage of natural genetic variation‚ modifying genes and transferring genes to new hosts. Gene technology sits within the broader area of biotechnology – the use of living things to make or change products. Humans have been using biotechnology for centuries

Behaviourist A perspective means a way of seeing things. Behaviourist is the first approach in this criterion. Behaviourist is the study of human minds‚ they study behaviour. The behaviourist sees the brain as a black box‚ this is because as they study animals it is easy to experiment‚ and they think that humans and animals are similar. The behaviourist wanted to become scientist‚ which is why they carried out the experiment. Although JB Watson (1887) was the founder of this theorist he studied

Genetic Engineering INTRODUCTION Genetic Engineering Involves methods‚ techniques‚ and procedures used in gene manipulation. Furthermore‚ it Involves isolation‚ manipulation and reintroduction of DNA into cells or model organisms‚ usually to express a protein to reach desired effects. Aim: to introduce new characteristics or attributes physiologically or physically Such as: making a crop resistant to herbicide‚ introducing a novel trait‚ enhancing existing ones‚ or producing a new protein

WHAT IS GENE THERAPY? Gene therapy is the transfer of recombinant DNA into an individual’s body cells‚ with the intent to correct a genetic defect or treat a disease. The transfer occurs by the way of lipid clusters or genetically engineered viruses‚ inserts an unmutated gene into an individual’s chromosomes. It is basically a method for fixing defective genes that cause diseases. As Starr‚ Evers & Starr (2013) stated‚ there are over 15‚000 serious genetic disorders in the world. Most of

DROSOPHILA GENETICS DROSOPHILA CULTURE We will study basic principles of Mendelian inheritance with the use of the fruit fly‚ Drosophila melanogaster [the name means “black-bodied fruit-lover”]. Drosophila was one of the first organisms to be studied genetically: its small size‚ short life cycle (10 ~14 days at 25oC)‚ high reproductive rate (an adult female can lay 400-500 eggs in 10 days)‚ and ease of culture and genetic manipulation have made it perhaps the best understood animal genetic system.

Subject: Detection of chromosomal abnormalities in prenatal samples. In this 21st century‚ due to fast life‚ marriages occur at late age‚ and thus‚ possibilities of genetic abnormalities in next generation rises. Consanguineous marriages may also the cause of genetical abnormality in feotus. Now a day it should be necessary to know genetic makeup of child before birth to prevent abnormal cases. To overcome this problem‚ detection of chromosomal abnormalities in feotus has been
