If you go to the circus today, you'll see elephants, clowns and cotton candy - not much of a freak show. Circus acts focusing on physical abnormalities might be a thing of the past, but that doesn't make them any less interesting. Below we present the 10 most bizarre circus performers who used their abnormalities to their advantage.Myrtle Corbin was born a dipygus, which means her pelvis and legs were duplicated.Prince Randian, also known as the snake man, was born without limbs.Here we have…

the loops contained tiny parts where a protein is called CTCF.Researcher found large parts of gene looped together. There were a lot of experiments that took place in my article talking about looping and folding DNA.They also talk about Y chromosome and X chromosome with the 3-D experiment. Folding happen in cancer cells they can use 3-D maps to help find a cure. This is just some of the experiments they did in the article I…

height ratio; in procedure 17.3 codominance will be observed in human blood, and the blood types of unknown samples will be determined. In procedure 17.4, Rh positive and Rh negative will be tested for in blood samples. A unit of heredity on a chromosome is called a gene. Mendel’s particulate theory states that offspring have characteristics inherited from their parents by genes that are passed from parent to offspring. The offspring receives one gene from each parent (Law of Segregation).…

disease developing. There are three different forms of genetic testing that can be done. These are gene tests where individual genes or relatively short lengths of DNA or RNA are tested. Another form of testing is chromosomal tests where whole chromosomes or very long lengths of DNA are tested. The last form of testing is biochemical testing, where protein levels or enzyme activities are tested. (FAQ) The DNA or RNA taken for a gene test is taken from a person’s blood, body fluids like saliva,…

Gene expression within a eukaryotic cell is directly impacted by the spatial organization of the nucleus [1]. Cellular organization is carried out at the chromosome-level [1], through means of chromosome folding, gene kissing, looping, nuclear lamina associations and protein-nucleic acid interactions within nuclear bodies. Observation of the nucleolus using Raman microspectroscopy may provide more insight into macromolecule density and distribution, as well as provide answers to the still…

Drosophila Melanogaster, or better known as the common fruit fly, is found all over the world and referred to as the cosmopolitan species (Mitrick, 2010). This fruit fly has three main body parts, which include the head, the thorax, and the abdomen. On males, the bottom half of the abdomen is black, while on the female, each segment of the abdomen is striped black. Drosophila have four main stages to their life cycle. These include: egg, larva, pupa and adult. The eggs small and translucent eggs…

meiosis has a synapsis of homologous chromosomes while mitosis does not. During daughter cell number and genetic composition, mitosis has two, each diploid cell is identical to the mother cell. While during meiosis this changes to 4 and each haploid cell contains half as many chromosomes as the mother cell and is inherently genetically different than the mother cell. Another difference is how the chromosomes align at the metaphase plate, during mitosis the chromosomes will align at the center,…

presence of more than two sets of chromosomes (3n, 4n, 5n, etc.) (Soltis et al., 2009) as sporophyte. Polyploids may have arisen as the result of nondisjunction during meiosis or may be generated when chromosomes are dividing properly in mitosis and meiosis, but the cytokinesis does not follow. Polyploidy can be classified into two: polysomic polyploidy (autopolyploidy) and disomic polyploidy (allopolyploidy) (Stebbins, 1951). Autopolyploidy comes from doubling of chromosome number within in…

partial loss of an X sex chromosome[2]. Symptoms of Turner’s syndrome include, but aren’t limited to short stature, glucose intolerance, broad chest and widely spread nipples, amenorrhea, webbed neck, aortic valve stenosis, visual impairments, hearing loss, problems with concentration, and nonverbal learning issues[3]. Not all individuals will present with the same combination of symptoms or with the same expressivity[4]. About half of the 2,500 births have only one X chromosome. This is called…

For instance, there are two types of chromosomes: autosomal and sex chromosomes. Sex-linkage behaves differently from autosomal chromosomes since males tend to have more impacts. In addition, crossing over can also happens between homologous chromosome; however, the frequency of having recombinant of two genes varies depending the gene loci. Crossing over can happens to any chromosome except for the male fruit fly sex chromosome due to unknown reason. Recombinant frequency uses to…
