Mutation- is a permanent change in organism’s nucleic acids (DNA/RNA). They can be results of mistakes in replication or transcription. Mutagens are chemicals that result in mutations (smoking‚ UV radiation) Two levels of Mutations: chromosomal level and point level. Chromosomal Level: Large mutations involving the entire chromosome (or large sections of them) and are almost never beneficial. Four types: * Duplication- Parts of a chromosome are made too many times * Translocation- Two non-homologous

There’s been a lot of discussion over the years about the proper way to refer to someone with dwarfism. Many people who have the condition prefer the term "little person" or "person of short stature." For some‚ "dwarf" is acceptable. For most‚ "midget" definitely is not. But here’s an idea everyone can agree on: Why not simply call a person with dwarfism by his or her name? Being of short stature is only one of the characteristics that make a little person who he or she is. If you’re the

Item #1: I was surprised to learn that the ancient Greeks practiced pederasty and were not considered pedophiles. I never heard of pederasty‚ so I was unaware of the difference. Ancient Greek pederasts were adult males‚ usually socially prominent‚ who have an erotic attraction to adolescent boys. These men would take on an adolescent male pupil and lover. Pederasts had bisexual relationships because many of the men had wives. And the sexual relationships with adolescent boys would not interfere with

Comprising over seventy percent of the Earth’s surface‚ water is undeniably the most valuable natural resource. Life on Earth would be non-existent without water because it is essential for everything on our planet to grow. The human body is composed of 50-80% water. Blood and muscles contain significant amounts‚ and approximately 95% of the brain is water. All body systems and organs need water to function properly‚ and will shut down without it. Most of the chemical reactions that take place in

usually caused by copying errors during replication that further leads to base substitution or deletion of one or more base pairs. Gene mutations can be inherited from a parent or acquired during a person’s lifetime. 4. Chromosomal mutation is also referred to as chromosomal rearrangement. It is an event that changes genetic structure. This mutation can involve deletions‚ insertions‚ or inversions of sections of DNA. In some cases‚ deleted sections may attach to other chromosomes‚ disrupting both

During the physical examination‚ we were unable to elicit findings typical of pneumonia such as dullness on both the lower lung fields‚ crackles‚ and increased breath sounds. We attributed this to the medications that were already taking effect on the day prior to conducting the physical examination. Administration of antibiotics and expectorants relieves the pulmonary congestion by reducing the bacterial load and purging the mucus that clogs the bronchi. The resolution of the disease in the patient

chromosomes. Typically‚ there are 23 pairs of chromosomes inside of each cell’s nucleus. We inherit half of these chromosomes from one parent‚ and the other half from the other. Sometimes‚ however‚ an extra chromosome can be present‚ creating a chromosomal condition called Down syndrome that occurs when an individual has 47 chromosomes instead of the usual 46. The extra chromosome present is either a full or partial copy of the chromosome 21 dubbing the condition with the alternate name of Trisomy

"copies" that occur are identical twins‚ which are duplicates of each other. "The first step of DNA cloning is to isolate a complete gene and is to chromosomal sequences and then to gradually begin flaking the chromosomal sequences of a single DAN molecule. Then the DNA clone can be electronically labeled and used as a probe to isolate the chromosomal sequences from a collection of different types of genes‚ which should contain cloned sequences that would represent the whole gene. This action will
