Introduction

Genetically modified foods or GMFs can be described as “foods derived from organisms whose genetic material (DNA) has been modified in a way that does not occur naturally, e.g. through the introduction of a gene from a different organism” (Verma & Singh, 2014). The techniques employed for the alteration of the genetic composition of a plant or an animal or the transference of genetic order from one life form to another have been introduced, developed, and promoted since the ending years of the twentieth century. Staple crops that are modified genetically like soya or corn are available in many regions Continue reading...

The Human Genome Project (HGP) was a scientific research project whose goal was to map the gene sequence of human beings. HGP was initiated and sponsored by the U.S government, but involved institutions and scientists from different regions of the world such as Japan, China, Germany, the U.K and France, making it the largest collaborative scientific research project of its kind. The project mapped about three billion base pairs (estimated to nbe between fifty and a hundred thousand genes). It started in 1990 after four years of development and planning and ended thirteen years later in 2003. Interestingly, the Continue reading...

Genetic engineering received both positive and negative responses from the public. Positive responses generally came from people who celebrated scientific advances while negative responses were mostly generated from the more conservative part of the population who believed that nature should be left untouched to preserve its sanctity.

Benefits and Disadvantages

Among the benefits of genetic engineering forwarded by scientists are related to agriculture. Through genetic engineering, increasing problems on urbanization, pests and shipping had been addressed. Urbanization reduced the area of farmlands resulting to decreasing quantities of harvests. However, though biotechnology, small farms are able to yield large harvests. Another advantage of Continue reading...

Abstract

Radiation cataractogenesis (RCG) is deterministic. It does not occur below a minimum threshold dose. RCG is generally believed as dose-related. Sliney (1986) believed that its severity is also dose-related. The severity increased and the latency decreased as radiation dose increased above that threshold. The lens of the eye is nonvascular and is known to experience no cell loss over its lifetime, indicating that any damage to its cells will not result to the removal of these cells for lack of existing mechanism. Three induction mechanisms were explored (direct, indirect, and oxidative, which separately creates oxidative stress inside the lens Continue reading...

Question 1

The unknown sequence is the sequence of nucleotides, so that’s why we have chosen the nucleotide blast search. There are four kinds of nucleotides in the sequence T, A, C, G.

Question 2

What is the name of the gene?
The name of the gene is an acronym of 8 letters that refers to the organism the gene is from.
It is MsFtsZ-mt. The full name is Mallomonas splendens FtsZ mRNA, it is nuclear gene that is encoding mitochondrial protein.

Question 3

What organism has the unknown sequence come from?
The scientific name of the organism is Mallomonas.
What supergroup Continue reading...

INTRODUCTION
Cancer is one the most feared medical diagnoses that any patient can receive. Granted we know a great deal more about cancer than in the past and many can be treated to a positive end, however, others are more risky. Breast cancer is a serious consideration for women. Today there are tests and measures that can be taken to identify, treat, and address the needs of breast cancer patients. Unfortunately, survival is still very much a matter of case by case basis. However, recent research has shown that there may be certain genes and hereditary markers that can Continue reading...

Abstract

The unity of a society is a requisite of social, economic, and political development and stability. Marriage is a formal union between men and women that creates such a highly important social institutions as family responsible for the viability of a community. If massive, a deviation from traditional marriage models can eventually bring a human society to the brink of extinction. Same-sex marriages is a union between individuals of the same sex undermine marriage and family as social institutions and makes it difficult, if not impossible, to raise children in a socially acceptable human environment demonstrating approved behavioral and Continue reading...

It is said that all it takes is one adult to make a difference in a child's life. In studying the origins of crime, especially we are focused on the influences of biology, heredity and genetics, it maybe be refreshing to study the origins of greatness. That will be an interesting study. To compare and contrast the study of biology and crime relation, a study of great people and their biological background will be a good sport. Charles Dickens, Victor Hugo, and even Ophra Winfrey came from shabby backgrounds. Using the study of biology and crime, can we predict Continue reading...

Abstract

Breast cancer is the form of cancer that develops in the breast tissue. It is usually represented by lump/s in the breast, dimpling and red scaly patch of the skin, change in the shape of breast, swelling in the armpit, and fluid coming from the nipple. There are different types of breast cancer, and the most important aspect of different cancers is the presence or absence of different receptors that are involved in the development or growth of cancer. Three important types of receptors that are related to breast cancer cells are Oestrogen receptor (ER) involving oestrogen, Progesterone Continue reading...

Alcoholism is generally a broader term for problem related to ethanol (commonly known as alcohol). It is generally known as alcohol addiction, which is the uncontrolled consumption of alcoholic beverages. It is generally considered a disease due to its addictive illness. The misuse of alcohol has the possibility of causing damages to almost all the human body organs, including the brain. The increasing toxic effect of chronic alcohol abuse can cause both psychiatric and medical problems in human. The biological factors that cause alcoholism are no clear. However stress, social environment, mental health, age, ethnic groups, gender and family Continue reading...
