This article addresses the development of healthcare for unborn children. In particular it focuses on Preimplantation Genetic Diagnosis (PGD) and the possibilities it offers in regards to genetic manipulation. It discusses the current state of genetic manipulation as well as the future of the practice. Lastly, the social and ethical ramifications of genetic manipulation are discussed.

A current topic being discussed in the scientific, medical, and public sector is the issue of antibiotic resistance. Microorganisms possess resistance to antibiotics in the form of DNA on genes that get passed between cells, and to their offspring. Antibiotic resistance has been present since the first implementation of antibiotics, and continues to be a problem.

The process of obtaining the sequence of a genome is simple in summary, but yet more complex during the literal process that is performed in the labs. With the aid of advanced science and technology, scientist are able to perform such a delicate procedure with a low error rate and a higher percent in accuracy.

This article will discuss the two types of prokaryotic transposons, simple and composite, as well as the two methods of transposition, replicative and conservative, employed by transposons. You will learn the differences between the two types of prokaryotic transposons and which method of transposition is used. Replicative transposition will be covered in detail as it is more complicated than conservative transpoition. Eukaryotic transposons will not be discussed.

Genetic variation stems from the recombination of DNA and also from mutations that can occur during this recombination. DNA-repair mechanisms exist to identify damage and correct the mutations, or changes in DNA sequence, but these very mechanisms can also introduce mutations. The following is a brief description of the many kinds of mutations that can occur in DNA and their resulting consequences.

Genetic engineering has been extensively used worldwide for many years to produce genetically modified fruits. here are many advantages of genetically modifying the fruits. Genetically modified fruits with pesticide resistance genes incorporated into them help eliminate spraying hazardous chemicals onto fruits. Genetic engineering also allows farmers to produce cold tolerance fruits. Genetic engineering can also make bigger and more nutritious fruits.

The immune system is one of the most important mechanisms the body has. It protects the body from most foreign and harmful viruses and bacteria.This system utilizes two types of cells known as B and T cells. The B cell goes through multiple stages in order to mature and to effectively locate and target the foreign organisms for destruction.

This article is about Down Syndrome, which is when an individual receives an extra chromosome (Chromosome 21). This doesn't seem like much, but it leads to so many disastrous complications within the bodies of individuals with it. This article explains all these complications and bring it to notice how lucky we all really are.

Readers should be able to learn about the different DNA point mutations that occur in eukaryotes and the types of consequences they have on coding regions. Readers should be able to define the different DNA point mutations and the consequences. Readers will also be able to understand how mutations lead to genetic variation in organisms.

Silent mutations, sometimes subcategorized into synonymous substitution or synonymous mutation, is the changing of a codon that mutates into another codon that codes for the same amino acid. Differences in silent mutations are only detected by sequencing the gene. What the name doesn’t explain is that silent mutations create new exons and introns the cell is not used too. When the cell splices the introns out and combines the spliced exons; it results in a different gene than needed. Th...

Mutations in a DNA sequence of genes can be harmful, helpful or neutral in an organism. Mutations may occur from surrounding chemicals, exposure to radiation or even a simple mistake made by RNA polymerase while copying the DNA strand. Mutagens are constantly creating mutations in the cell while repair proteins are constantly working to fix them.

This articles explains the main types of mutations and provides excellent examples of mutations. While mutations do change the DNA, different types of mutations have different results, which can be hard to differentiate. What makes mutations very unique is they have various effects and tend to be complex since no two mutations are the same. This article also demostrates that mutations are either minor or major depending on the severity of the alteration.

Point mutations are simple mutations; however, there are different types of point mutations that can cause minor and major consequences to both the DNA sequences and protein structure and function. This article will explain and defined the two main types of point mutations along side with the mutations they cause on a molecular scale.
