SC435- Genetics

In the study of genetics, it is important to understand how a protein is made from the DNA sequence. Recent advancements have also highlighted how important it is to control how much of a protein is manufactured in the cell. Control over gene expression allows the cell to self-adjust to its needs. Studying control of […]

Selected Disease Cockayne syndrome; also known as Neill-Dingwall syndrome. It was named after Edward Alfred Cockayne, an English Physician who first described it (1880-1956). The second name is associated with two women (Mary M. Dingwall and Catherine A. Neil) who also described it in two patients and asserted it was the same as the one […]

Experiments have been used in the past to demonstrate that DNA is the transforming principle. Bacteriologists initially suspected that the transforming principle was a type of protein until they discovered that alcohol could be used to precipitate it, that proteases and lipases could not destroy it, and that it was rich in nucleic acids and […]

Antibiotics are a range of medicines that work against infections through extermination or containment of bacteria (Ventola, 2015). Technically, any drug that kills disease-causing germs in the body is an antibiotic, but many people prefer to use the term when referring to medicines that kill bacteria.  Bacteria can become resistant to antibiotics through genetic mutation […]

Genetics: Unit 3 Assignment Genetics includes the study of our genetic makeup and how that influences physical traits or disease states. Our genetic makeup can be defined by the contributions from both parents. Your workplace is trying to solve an issue and because of your genetic expertise they have asked you to prepare answers to […]

A telomere represents a region of recurring nucleotide chains at each end of the chromosome (Pierce, 2013). Telomeres serve three main purposes in a cell. First, they facilitate the organization of all 46 chromosomes in the cell nucleus. Second, they protect the ends of the chromosome from deterioration and fusion with neighboring chromosomes. Third, they […]

Inheritance of Blood Types A child born to parents with the aforementioned blood types may have blood type A, B, AB, or O with a positive rhesus factor. This is because the child’s blood type will be determined by the co-dominant alleles, which are A and B. Notably, alleles refer to genetic information stored in […]

Unit 2 Overview and Outcomes Welcome to the study of heredity — the inheritance of traits. In this unit, you will begin the study of heredity by examining how chromosomes are transmitted from one cell to the next. Each of us started from a single fertilized egg that had 46 chromosomes — 23 from your […]

Genetics Lubke, McArtor, Boomsma, & Bartels (2018) analyzed a sample of 21,565 girls and 21,262 boys aged 3-16 years from 21, 608 families in the Netherlands Twin Register to explore environmental and genetic contributions to child aggression. They used auto-regressive models to evaluate whether the same genes are enmeshed as children grow up. The researchers […]
