Discuss The Advantages And Disadvantages Of Fetal Marker Scanning For Chromosome Abnormalities
Introduction Since ultrasound was first use in the late 1950’s, it has been a very helpful diagnostic tool in Obstetric. Prenatal ultrasound (also called fetal ultrasound or fetal sonography) has become an almost regular part of the antenatal care during visits to the obstetrician (Woo, 2005). Ultrasound (sonogram) is used to provide detailed images of the fetus and uterus during pregnancy.  The ultrasound probe emits sound waves which give an image the baby and placenta. Therefore, its painless ...

Components and Processes within a Polymerase Chain Reaction
The paper "Components and Processes within a Polymerase Chain Reaction" is a perfect example of an assignment on biology. A polymerase chain reaction is a form of scientific technique that is made use of in the amplification of pieces of DNA that result in a great number of copies of a type of DNA sequence. The technique relies on the complementarity of the bases of DNA. It is noted that in the event a DNA molecule is heated then the hydrogen bonds that hold the double helix structures are denatured ...

Gender Differences and Gender Socialisation
The paper "Gender Differences and Gender Socialisation" is a good example of a term paper on sociology.Throughout history, various scholars have evaluated gender issues. Gender can be defined as the inner sense of one’s being that is psychological in nature. This is not considering the outside physique emanating from the sexual organs that one has. It is known that human beings have two distinct genders. These are the male and female or feminine and masculine. Differences have continued to ...

Bird's Sex Identification Using DNA Markers
The paper “Bird's Sex Identification Using DNA Markers” is a meaty example of a lab report on biology. DNA was isolated from three types of samples these are blood, feathers, and muscle tissue. The collection of blood as a sample for DNA extraction could be from a live bird or a dead one. The sample should be fresh to maintain high quality and quantity of DNA and to prevent contamination. Fresh blood samples can be stored in 95% ethanol at room temperature or frozen. Feather samples could ...

Cell Division and the Musculoskeletal System, Importance of Mitosis and Meiosis
The paper “Cell Division and the Musсulоskеlеtаl System, Importance of Mitosis and Meiosis” is a well-turned example of coursework on biology. Generally, cells divide in two ways; the first way is mitosis, the second way is meiosis. Mitosis is a cell division process whereby an individual cell undergoes cell division which results in two daughter cells. Meiosis is basically a process whereby single cells undergoes cell division, the cells divide twice and produce four cells, whereby each ...

The Use of Biochemistry in Forensic Science
The paper "The Use of Biochemistry in Forensic Science" is a good example of a literature review on biology. According to Templin (2001, p.1), biochemistry deals with matter molecules ‘biomolecules’ which make up living organisms. Nuclei acids, lipids, carbohydrates, and proteins are vital to biochemistry. Biochemistry is also associated with the structure of the function of the biomolecule. Biochemistry has been utilized to bridge between biology and chemistry; it’s also a major ...

What Changes in Cells and DNA Lead to Cancer, and How Do These Changes Affect the Cell Cycle
The paper “What Changes in Cells and DNA Lead to Cancer, and How Do These Changes Affect the Cell Cycle?” is a potent variant of an essay on biology. Cancer terminology refers to a multitude of conditions with uncontrolled and unscheduled cellular proliferation characteristics. In biology, many homeostatic processes revolve in competitive interactions. The secretion of paracrine and autocrine factors important in preventing neighboring cells from anomalous growth, subsequently resulting ...

Cell Development - Stages of Cell Division, Tissue Development, Epithelization, Sense of Touch
The paper “Cell Development - Stages of Cell Division, Tissue Development, Epithelization, Sense of Touch” is a well-turned variant of essay on biology. Cells show a lot of variation in their sizes and structures. Consequently, they have two main parts. These are nucleus and cytoplasm. The two main parts are enclosed in a cell membrane, which is sometimes called the plasma membrane. On the other hand, tissues are the organizational level of the cell, which is intermediate between a complete ...

What Factors Affect The Preimplantation Embryo Development
Factors affect the preimplantation embryo developmentDevelopment of the preimplantation embryoThe preimplantation embryo passes through several metabolic phases, undergoing changes in protein synthesis, energy requirements and amino acid uptake as it develops from a fertilized zygote to the blastocyst stage. Alongside, it also undergoes morphological changes, particularly at compaction when the first differentiative process is observed (Sakkas and Vassalli, n.d.). The preimplantation development ...

The New Genetics of Mental Illness by Edmund S. Higgins
The paper "The New Genetics of Mental Illness by Edmund S. Higgins" is a brilliant example of an article on biology. Proteins, which are produced as a result of gene expression, are primarily involved in the maintenance of the brain and body. There are various factors that contribute to gene expression as a result of which the same genes are expressed to a different extent or not expressed at all in certain cells. The DNA is transcribed into an intermediate molecule termed RNA, which in turn is translated ...
