In the past six weeks of genetic lab we have been doing an experiment about fruit fly (drosophila melanogaster); we had the opportunity to learn more of how to distinguish between the male and female drosophila; one way that helps me was to look for the sex comb and the size. The purpose of this experiment was to learn more and be able to understand the Mendelian Genetics. We did an actual cross of fruit fly (drosophila melanogaster) such as the monohybrid, dihybrid, X-linked A, X-linked B and…

Everyone has heard of the blood types A, B, AB, and O, but not everyone understands what these letters mean. A blood type or blood group is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells. When you receive a blood transfusion, doctors have to make sure it is a match to your blood type, if not it can kill you (Wayman, 2012). The blood types A, B, AB, and O are known as the ABO blood group (Wayman, 2012). This blood…

After transcribing and translating the sequence I found out that the protein from my DNA sequence is Dystrophin. Dystrophin is known as the DMD gene or Duchene Muscular Dystrophy. (“DMD”, 2015)This gene is one of the largest known human genes in the body. Dystrophin is used for movement such as your muscles and your heart. Dystrophin also plays a role in cell signaling. This sends and receives protein chemical signals. (“DMD”, 2015) Dystrophin is not only important for the structure, but the…

A single gene can mean the difference between a normal life and a very difficult, painful, or even very short life. With technological advances in the field of genetics, such as the CRISPR-Cas9, it is now possible for geneticists to eliminate these single gene mutations that are lethal, extremely dangerous, or unbearable to the human race. Harlequin ichthyosis, cystic fibrosis and Smith-Lemli-Opitz syndrome are all caused by single genes and can potentially be edited out of the human genome.…

The first claim made in “Future Humans” is that humans are no longer evolving. Ian Tattersal believes that evolution only occurs in isolated populations: homo sapiens are now so vastly spread among the world, evolution has come to an end. He also believes the more time that passes the more homo sapiens will begin to look alike. This part of the article also discusses how natural selection is no longer applicable for humans. Natural selection is essentially “survival of the fittest”, and now…

A virus is a small infectious agent. There are different types of viruses. Viruses are all over the world and can be caused by many things and substances. Viruses are nonliving, it contains genetic information, has to survive (DNA/RNA) in a host, and can multiply from 1 virus to 1,000. Viruses have 3 components. Capsid surrounds DNA, Tail sheath-connected to capsid, and tail-fibers-connected to the sheath. The virus DNA travels down the tail sheath through the membrane. The virus tricks the cell…

Title: Which Antibiotics Kill the Most Bacteria? Caroline Gorman April 2, 2016 HB bl. 6 Purpose: The purpose of this lab was to determine which of five common antibiotics would kill the Rhodococcus rhodochrous bacteria. Hypothesis: Out of the five tested antibiotics, doxycycline will kill the most Rhodococcus rhodochrous because it is generally used to treat mild infections. This will be tested by spreading the bacteria on agar in a Petri dish and adding a small amount of each antibiotic…

Imagine getting dislocated joints and sunburns really easily. That’s what people with Ehlers Danlos Syndrome (EDS) get easy. EDS is a genetic disorder that affect the joints and skin. There are 6 different types of this disease, Classical type, Hypermobility type, Kyphoscoliosis type, Arthrochlasia type, and the Dermatosparaxis type. The mutations for this disease happens on these chromosomes, the Classical type is mostly on chromosome 9 or 2, the hypermobility type is on chromosome 6, the…

Scientists have shown that there is a development in polyploidy, which means that you have more than two sets of chromosomes. As polyploidy is somewhat confusing, there is two articles of explanation on this subject. I want to start by explaining gene doubling in an easier sense due to its confusion. Polyploidy can occur when organisms self-fertilize or through sexual reproduction. Through research, it's said that this process can possibly create a new species after being done. Although,…

Biology plays quite a lot on personality, people can be more likely to develop certain personality traits because they inherited them genetically. That is what biological psychologist’s study’s. There is an entire field of science called epigenetics that is all about how changes in behavior due to experience can affect people on a biological level and cause changes in genetics across generations. It’s far from the only thing that influences personality but it plays the part. Heredity plays a…
