  • Y Chromosome Evolution

    Y chromosome is a sex determine chromosome among many species including modern humans. Modern studies in genome suggested that Y chromosome arose from the accumulations of mutations of other chromosomes and have some special genes on it which determine the gender of the carrier; however, some non-mammalian animals carry the Y chromosome even if their genders are not determine by the appearance of the Y chromosome. The Y chromosome works differently on the mammalian and non-mammalian so in this paper when an aspect about Y chromosome is brought up, it well be discussed in both mammalian (use human as example) and non-mammalian (use Drosophila as example) case. The paper will mainly focus on three point: how Y chromosome originated; the function…

  • Movie Analysis: 23 Chromosome

    This film explains how all humans are created. There are around 365,000 new babies made around the world everyday. Our bodies natural instinct is to make babies. It is what we were made to do. Even when we aren't doing the"physical" part of it, our bodies are still creating eggs and sperm to get us ready to try to reproduce. Our bodies are made up of DNA. DNA is made up of chromosomes. We get 23 chromosomes from our dad and 23 chromosomes from our mom. We are made up of 46 chromosomes to make…

  • Unit 3 Chromosomes Essay

    3 Chromosomes are thread-like structures which consist of DNA and other proteins. Chromosomes are present in every cell of the human body so that information can be carried for that cell to develop. The human body normally consists of 46 chromosomes which then can be paired into 23 pairs. 22 pairs of chromosomes are similar in both males and females which are commonly known as autosomes. However, the 22nd chromosomes (X and Y) are different as these are the sex chromosomes. The human cell can…

  • Essay On Chromosome Looping

    DNA organization within cells is a complex and sophisticated process. This high level of complexity is due to the hundreds of thousands of interactions that can be enabled through organization. It is a known that promoter elements and enhancer elements work in unison to regulate gene expression. Often times enhancers are found hundreds of kilo-bases away from their interacting promoter elements. These enhancers initiate promoter activation via interactions amongst transcription factor binding…

  • Genetics Down Syndrome

    Genetics To Down Syndrome Genetics describes the makeup of our cells, genes, chromosomes, and phenotypes. When there is alter in a gene or a duplication of a chromosome, it can lead to a certain diseases. One of the main diseases known today from a duplication of a chromosome is Down syndrome. John Down first put a name to Down syndrome in 1866, but artifacts from Mexico and Saxon documented some cases of Down syndrome in individuals, and also some were found in paintings of the Renaissance in…

  • Huntington's Disease Analysis

    Previous studies have established that the gene responsible for Huntington’s disease (HD) is located in chromosome 4 – labeled as 4p16.3. Early symptoms of the disease include chorea or involuntary movements, loss of balance, as well as cerebral atrophy1. Although the disease has a late onset, juvenile form of the disease is also probable. The disease is manifested in children and teenagers and is characterized by transmission from an affected father (paternal transmission effect), unusually…

  • Downs Syndrome

    Every cell in the body is not exactly the same, 1% of the syndrome cases most cells in the body have an additional chromosome while some don’t this is known as mosaicism. The Mosaic trisomy 21 takes place when the error in the cell division happens early in development though it is after the sperm and the normal egg unite. This can also take place in early development when there are some cells who lose an extra chromosome 21 which was present at conception. Symptoms for this form vary between…

  • Russell-Silver Syndrome

    Did you know there is an average of 20,000-25,000 genes per one single chromosome? And one change or shortage in such a minute item can cause a major condition, disease, disorder and even cancer. Chromosomes seven - twelve have large number of gene pairs and genes that are roughly the following; chromosome 7 spans about 159 million DNA base pairs and likely contains 900 to 1,000 genes, chromosome 8 spans more than 146 million DNA base pairs, and likely contains about 700 genes, chromosome 9 is…

  • Meiosis And Miosis: The Three Types Of Cell Division

    Meiosis and mitosis are more complicated processes of cell division. Mitosis is part of the process used when a cell replicates itself, in its exact form. The cell duplicates perfectly, with the same DNA. During this phase, the chromosomes align, separate, and are moved to the opposite ends of the cell, forming two identical cells (OpenStax, 2013). Within this phase, there are five sub-phases called prophase, prometaphase, metaphase, anaphase, and telophase. An example of mitosis would be the…
