Chromosomes

According to the observation made during the replication of Drosophila melanogaster chromosomes in 1973, the opening of Drosophila’s DNA double helix, known as replication forks (formerly named as eye forms) at a number of different sites were noted (Kriegstein and Hogness, 1974). The creation of replication forks is the result of the formation…

Recently, the growing research for the study of transgenderism and gender dysphoria is pointing to biological origins. In 2008, Australian researchers conducted an experiment on 112 transgender women (male to female individuals) compared to 258 non-transsexual males. It was discovered that there was a genetic variation in transgender women – they had higher chances of having a longer version of the androgen receptor (AR) gene, meaning that it is less responsive. Androgens are hormones, such as…

AETIOLOGY OF ALLERGIC RHINITIS Genetic predisposition Genetic predisposition is a major factor in the aetiology of AR. The clinical evidence include: the fact that a family history of allergic rhinitis is often present and the association of Allergic rhinitis with other atopic diseases that possess a genetic basis, such as allergic asthma or atopic dermatitis. It has been reported that Allergic Rhinitis has a hereditary component but does not exhibit a Mendelian hereditary pattern. The…

congenital heart defects and this disorder increases the risk of having leukemia. The risk of a child having Down’s syndrome increases after the age of 35 in mothers. Around 88% of all cases of Down’s syndrome come from the mother’s chromosome and 8% from the father’s chromosome. The extrapolated incidences of Down’s syndrome in countries around the world is about 1 out of 1000 (Right Diagnosis…

Project, how it apply to our health and how it evolved around society. My generation was the one that grew up with the Genome Project. During the process of the Genome Project, scientists took a look at a human’s cell then at the chromosome individually. After the chromosomes were separated, they cut down to the basic A, T, C and G that are in DNA. The project didn’t cost as much as what scientists proclaimed. Another thing was that it didn’t take as long as they thought it would. If you search…

Gene mutation is a permanent alteration in the DNA nucleotide sequence, such that the sequence is different from what is commonly found. Mutations range in size; they can affect anywhere from a single base pair, to a large segment of a chromosome. Gene mutations can be categorized in two major ways, hereditary and acquired or somatic mutation. Hereditary mutations are mutations inherited from a parent. These mutations are present in virtually every cell of the body, and are present throughout…

Thorough description of the disorder Huntington’s disease is a genetic disorder that affects muscle coordination and leads to mental decline and behavioral symptoms. It breaks down nerve cells in the brain called neurons. Neurons are specially designed to transmit information. When neurons break down, the body can’t control all of its movements. The brain controls the entire body and when the nerves in the brain break down, it causes your body to glitch. This is why a person with this disease…

The only way to create another gender is to use some sort of gene splice experimentation and create your own gender. Whether you want to know it or not, people either have a homogametic (XX) chromosome meaning you’re a girl, or a heterogametic (XY) chromosome meaning you’re a guy. There is no identifying as a plant, there is no gender fluid, its either you’re a guy or…

Eukaryotes (which contain a nucleus) have their genetic information stored in the nucleus in the form of chromosomes; while prokaryotes, (which do not contain a nucleus) have DNA floating in the cytoplasm in the form of plasmid. Nucleotides that make up DNA are very similar except for the difference in nitrogenous base that each one contains. These bases include…

It’s no doubt that people are born with traits, ethnicity and gender. But can someone be born gay? In other words is being born gay heterozygous? Although there isn’t an exact definition of being born gay, in this case, it can be defined as being born with a homosexual gene or trait. Most lesbians, gays, and transsexuals (LGBT’s) argue that they were born gay. Others argue that being born gay is not heterozygous. With the biological evidence, we can truly determine whether it’s true or not.…
