Chromosome

The chromosomes involved in Alzheimer’s are 1, 14, 19 and 21. The chromosome involved with Down syndrome is 21. People with Down syndrome will often get Alzheimer’s symptoms, although the symptoms will be demonstrated at a younger age then others who get Alzheimer’s. Scientist’s today are still…

Prader-Willi syndrome happens when the genes in chromosome 15 are not there or do not work. The nonworking area is always found on chromosome 15 which is passed down from the father. This syndrome is tied to a process called genetic imprinting. In order for regular development to proceed, genetic imprinting must be exact. Prader-Willi syndrome has been linked to flawed genetic imprinting. In the majority of cases, the area of genes in chromosome 15 attributed to the father is absent. Therefore,…

cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes. 2. Insulin, a peptide hormone, which is released into the blood by the pancreatic beta cell when the blood sugar level is too high (hyperglycaemia) in a regulated secretion pathway to maintain normal blood sugar level (Normoglycaemia), and…

Hemophilia is a disease that is inherited, meaning it often runs families. All humans have two chromosomes determining their gender XX for females and XY for males and because the disorder is only carried on the X chromosomes males are affected the most. Since males only have one X chromosome and females have two X chromosomes, one from both parents, they’ll typically have one normal X chromosome, they’ll be unaffected by this disorder since it is a recessive disease and instead will only become…

an individual inheriting, passing on, or living with a suspected genetic condition. These medical tests identify any changes in proteins, chromosomes or genes (NIH, 2018). Accessible to the majority of the population today, there are several methods of genetic testing including; biochemical tests, relating to proteins; chromosomal tests, analysing chromosomes for large genetic changes; and molecular tests - studying particular genes for inconsistencies or mutations. Availability, cost and…

After proper research, DNA and the Gene are two quite similar things. Each person contains this in their body. DNA can be found in mostly any part of the body, it could also be found in plants and other species. DNA and the gene are just part of the most important things that we have in our living system because this is what makes us look like our relatives. DNA is part of living things and if someone looks like their parent this is because they have the same Genes. Every living organism…

the inside. The opposite could be true as well. Not only can a person be born with both, they can also be born with genitals that seem to be in-between the usual male and female types or born with mosaic genetics, so that some the cells have XX chromosomes and some of them have XY. This can be particularly confusing for someone growing up and not exactly knowing how their biological gender may fit into the world or society. Since biological gender is one basis for developing gender identity, not…

In their first biology classes, children are taught that people are either born as a girl, with two x-chromosomes, or as a boy, with one x-chromosome and one y-chromosome. It is generally thought that these two genetic variations are the main determinants of a person’s identity. In reality, however, they are rather meaningless. It is society that gives these anatomical differences meaning. “Society constructs and interprets perceived differences among humans and gives us ‘feminine’ and…

The phallic stage is the most important when it comes to gender. In the phallic stage, boys develop the Oedipus complex and girls develop the Electra complex. This is where they reject their desires for the parent of the opposite sex and this rejection forces them to identify with the same sex parent. The identification is more powerful for boys because they have castration fear if they don’t reject attraction for mother. They realize that their father stands in the way of the satisfaction of…

Genetics is the field of study that investigates how particular qualities or traits are passed on from parents to their offspring. Genetic information is passed from parent to offspring via chromosomes. Human beings have 23 pairs of chromosomes which contain between 20,000 to 25,000 genes, some of which determine their inherited physical traits such as eye colour, skin colour, and body shape. Offspring can also inherit some non-physical traits from their parents including disease. Sickle Cell…
