Using a 40cm piece of string, make another circle inside the cell to represent the nuclear membrane. o Fold each of four strips of paper in half, lengthwise. Then place one strip of each color inside the nucleus to represent a chromosome before replication. The light and dark strips of the same color represent homologous…

Structure DNA and RNA are nucleic acids. Nucleic acids consists of minor particles called nucleotides. In DNA and RNA, these nucleotides contain four nucleobases —nitrogenous bases or bases — two purine and two pyrimidine bases. DNA is found in the center of a cell (atomic DNA). It has two nucleotide strands which comprise of its…

Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613C,…

Can Genetics Cause Crime? Introduction to Criminal Justice System Dr. Mike Carlie Are genetic factors more likely to make one person perform violent acts? Many doctors and researchers in the field of genetics have searched for a answer to this question. During 1989-93 one such researcher named Dr. Sullivan found some interesting points about genetics…

Variation among the individuals of a population due to their genetic constitution is important for varietal adaptability and effective selection. The biological variation consists of (1) Phenotypic (2) Genotypic and (3) Environmental components. The phenotypic variability consists of genetic and environmental variation and is observable. The genetic variability is the inherent variation which consists of…

Is a problem that affects all members of society. There is no doubt that aggression pays off for some people. Parents who yell and threaten punishment get results. The child who hits the hardest gets the toy. The brother who is willing to be the most vicious in a fight wins. The teacher who gives…

Two years ago Scottish scientists announced that they had successfully cloned a sheep. They named it dolly and it was an exact copy of the original sheep. Is cloning morally right? Is it ethical? Some people think that it is wrong and that it shouldnt be practiced on any animal. In this report I will…

DNA fingerprinting (the use of a persons DNA to identify them) has become a hot topic in the field of law enforcement as well as the entire world. The controversy exists on whether or not it should be admitted in court as evidence at this time. Some experts believe that the present technology allows DNA…

Mechanism of action of ciprofloxacin DNA synthesis is interfered by sealing DNA gyrase ( topoisomerase II ) and topoisomerase IV. Two sets of subunits, 2GyrA and 2GyrB that are encrypted by genes gyrA and gyrB severally consists DNA gyrase enzyme. DNA rupturing and association are processed by genes gyrA. Unique negative supercoiling continuation of DNA…

The steps involved in the biosynthesis of proteins including the roles of RNA Protein biosynthesis is the process in which the DNA codes specifically to produce many amino acid monomers and proteins. It Is a necessary process for the development, growth and maintenance of a cell. Proteins are needed in the cell for many reasons,…
