Free Genetics Essay Examples to Learn From

1. Introduction:
The genetic information of a cell is coded in its DNA sequences. A base change in this DNA sequence causes a corresponding change in the genotype and the corresponding phenotype. These changes are often inherited by the progeny cell during cell division. Now we know that phenotype is not just influenced by the genetic information stored in the DNA sequence, but also the micro and macro environment of the cells. Two identical DNA sequence can give different phenotypes in different environment. Even two genetically identical twins when raised in different environment can show a number of variations.

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...

Introduction

The Transcription elongation factor B, polypeptide 1 is a protein variant that in the species Homo sapiens is encoded by the TCEB1 gene also referred to as SIII or eloC (National Center for Biotechnology Information (NCBI), 2015, sec. 1). Structurally, the SIII Complex is a heterotrimeric compound composed of three elongins sub-units – elongins A and A2 (110kD), B (18kD), and C (kD). However, further analysis divulges that elongin C protein is a subunit of the transcription factor B framework (otherwise referred to as elongin SIII complex) (GeneCards, 2014, sec. 1). Functionally, the SIII compound purpose is the activation of 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...

Food is an essential basic need that every person desires. In the old days, the production of food was only through hunting and farming which took a long period before these foods arrive on our table. Nevertheless, today, technology has made it possible for food to take the shortest time before harvest as well as enabling mass production of food. Unluckily, the markets and politicians are taking an advantage of technology to influence the world to embrace the birth of Genetically Modified Organisms. GMOs are organisms especially plants and animals whose genetic code has been altered to make them Continue reading...

INT. DANCING CLASS – EVENING
In a dance room, six women and two men move from right to left, front and back, following the instructors’ indications, a middle aged woman, but highly spirited. GENE and NILES dancing next to each other on Irene Cara’s “What a Feeling”.

NILES

One, three, free, four, one, three, free, four. That’s the rhythm. Tired much, Robbins?

He talks to Gene, calling her on her surname, watching her slyly, while elegantly executing the steps.

GENE
Watch out, Hoffman, those pants of yours are gonna fall from all the excitement.

Got anything I’d be interested in, Hoffman?

“Epigenetics” from Nova

Epigenetics can be defined as the science of studying the chemical influences on genes that turn on some traits and suppress others. The video, “Epigenetics” from Nova on PBS was a very interesting video which explained epigenetics and its effects. Science has led us to believe that genes are responsible for our physical appearance, personality, and behavior and pre-disposition to disease. Current research into epigenomes and their functions is both raising questions and providing some answers as to why some genetic traits are evident in people while others are not.
The video studied sets of identical twins who are Continue reading...

Introduction

Through the use of genetic engineering and advanced technology, man has been in a position to modify the DNA and other traits of food producing animals and plants to improve their productivity and the level of survival. The commercial sale of animal and plant products that are genetically engineered began as early as 1994 (Crespi, John & Stéphan, 327). The need to undertake genetic engineering of crops and animals has been facilitated by various issues. To begin with, environmental and climatic changes affecting the survival rate of cash crops and animals have compelled scientists and biotechnologists to come up Continue reading...
