analyses at 15 loci on chromosome 1 and at 16 loci on other chromosomes confirmed parentage and revealed that a de novo mutation prior to maternal meiosis I, followed by nondisjunction in maternal meiosis II, resulted in an oocyte with two copies of the de novo (an alteration in a gene that is present for the first time in one family member as a result of a mutation in a germ cell) mutant allele.” Therefore during the fertilization by a sperm that did not carry a paternal chromosome 1, the child…

mucoviscidosis is an extremely common genetic disease in the UK. The genetic defect was identified by a group of scientists in 1989.In the UK it has been found that 1 in 25 people carry the faulty CF allele. CF is caused by deletion of 3 nucleotides in chromosome 7. The amino acid phenylalanine is lost as a result of this mutation. It is autosomal recessive so both the CFTR alleles should be faulty to cause the disease. Many of the epithilial linings of the ducts in the human body have a layer…

A Pseudogene is a gene that lost its gene expression in the cell, or lost the ability to code protein. 2. Name of the gene: CFTR 3. The gene CFTR is located on chromosome 7. 4. Transcript: is the process when a segment of DNA is copied to RNA. 5. Transcript: CFTR-001 - cystic fibrosis transmembrane conductance regulator. Length: 6132 bps. 6. Exon: a segment of a DNA or RNA molecule containing information coding…

complete complement of chromosomes. The first stage of meiosis is called Interphase. This is when the chromosomes are duplicated in preparation for the division. The next 4 stages are referred to as meiosis I. Prophase I is when the homologous chromosomes pair up and exchange segments. Metaphase I is when the pairs of chromosomes line up along the spindle. Anaphase I is when the pairs of chromosomes split up. The sister chromatids remain attached. Telophase I is when the chromosomes arrive at…

disorder. At first, Jazz’s parents found it hard to accept that their child is a transgender, but eventually understands after a period of time. When it comes to determining a person’s biological sex, there are three factors: genitalia, gonads and chromosome patterns. In the case of Jazz, she has the physical…

1. Explain how an enzyme works, and how a coenzyme or cofactors may be involved in an enzymatic reaction. An enzyme is a type of protein that is produced by living organism, that also speeds up a chemical reaction without actually being involved in the reaction itself. Reactions occur under mild conditions; enzymes also control the metabolism, by taking out nonspecific side reactions. Enzymes catalyze each step of the chemical reactions in a metabolic pathway. In order for this to happen, all…

being in the health field is science if you want to be a paramedic your going to need to know how to keep the body alive till the doctors are able to. being a paramedic you're going to need to know how much medicine your patient needs or how the patient will still be alive when they get to the doctor. Anything in the health field is science. if you wanted to be in diagnostic services that would involve treating a problem through monitoring problems and following up on any abnormalities like…

X gene since it is carried on an X chromosome. If the father carries the gene for Fragile X, he will pass it on to his daughters 100% of the time, but none of his son’s would have the disorder. Since women can only pass on X chromosomes to their children, a mother with the altered gene for Fragile X can pass that gene to either her sons or her daughters. There is 50/50 chance her children will have the disorder given that the father has a two regular X chromosome. Is there a treatment or cure?…

This occurs when a pair of the twenty first chromosome in the egg or sperm does not properly divide, resulting in the child having three copies of chromosome 21 instead of just two. The extra copy of chromosome 21 is reproduced in every cell of the unborn child’s body. This type of Down Syndrome is more common than any other type. It is the cause behind 95% of all people with…

He discusses how chimps and humans both have the same 23 Chromosomes in their body. This alludes to how human’s evolved from monkeys and other primates. With all of the similarities between humans and primates, it almost seems as if evolving from primates was the only way humans came to this earth. The genetic difference…
