Is gene therapy the most effective way to treat depression? What really is depression? The term ‘depression’ can be defined in two different ways: 1. Severe despondency and dejection‚ accompanied by feelings of hopelessness and inadequacy. 2. A condition of mental disturbance‚ typically with lack of energy and difficulty in maintaining concentration or interest in life.1 Majority of people believe that depression is somewhat trivial and is not regarded as a genuine health condition‚ but

To aid us in the classification we are given the gene sequence of 3 other species in which share similarities with the gene of interest: Gene #1: gallus gallus collagen‚ Type V alpha (Bird)‚ anas platyrhyncas‚ e=0.0. Gene #2: drasophila melanogaster shaker(sh)‚ haematobia irritans exigua 95% similarity‚ e=0.0. Gene #3: Taeniopyqia guttata (zebrae finch)‚ geospiza fortis 99%

eye colour) genes are called alleles. If a person inherits the same form of a gene from the mother and the father‚ that person is said to be homozygous. If a person inherits two different forms of the same gene‚ they are said to be heterozygous. Some alleles are dominant‚ whereas others are recessive – dominant are the genes you will display if you get two different types of genes. • The variation of alleles at several loci can be combined to provide

uses the sequence information within a set of housekeeping genes to determine the type of the organism. For each gene the dissimilar sequences are noted to be different alleles. MLSA is very similar to MLST but uses linked sequences to derive a phylogenetic relationship. MLSA is generally used to progress species descriptions whereas MLST is used with species that are already distinct. In this lab we are performing MLST. 2. The 16s rRNA gene is highly conserved and therefore does not rapidly accumulate

Inheritance - The genes associated with these conditions are located on the X chromosome‚ which is one of the two sex chromosomes. In males (who have only one X chromosome)‚ one altered copy of the gene in each cell causes the condition. In females (who have two X chromosomes)‚ a mutation would have to occur in both copies of the gene to cause the disorder. What is the role of genetic testing ? - Genetic testing for Hemophilia A&B is to check for mutations within the genes. DNA testing would

Genes contain all the information of the DNA of an organism. Genes are fractions of a DNA which can be inherited in reproduction. New organisms share a group of genes which come from the parent gametes. All the inherited genes form a new DNA chain. Genes determine all the physical details of an

Speciation essay A species is a group of organisms that can breed together to produce fertile offspring. New species arise in two ways‚ hybridisation and polyploidy. Polyploidy is an increase in the number of sets of chromosomes. Hybridisation is the production of offspring from parents of two different species‚ this means though that the offspring is not fertile such a mule‚ a cross between a horse and a donkey‚ which is why hybridisation can only be explained in plants and not animals.
