at least 100 words: 1. Describe the structure of DNA. ➢ DNA is a nucleic acid‚ which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides‚ each a chain of nucleotides. Each nucleotide consists of a nitrogenous base‚ a sugar‚ and a phosphate group. Each DNA strand serves as a mold‚ or template‚ to guide reproduction of the other strand. There are four different types of nucleotides found in DNA‚ differing only in the nitrogenous

Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are negatively

Aims: The materials aim to cover some of the MoE’s (Ministry of Education) learning outcomes such as familiarity and correct use of parts of speech‚ syllables etc. Poetry is a Ministry curriculum genre to be used both for passive analysis as well as a productive skill and teachers shy away from it for many reasons‚ which I will deal with later. Evans (2001) proposes poetry as a good medium for teaching creative writing‚ something parents and the MoE want but schools find hard to teach.

of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term science also refers to the organized body of knowledge people have gained using that system. Less formally‚ the word science often describes any systematic field of study or the knowledge gained from it. (Science Made Simple‚ Inc.‚ 2006). Since in the beginning of time‚ we have conducted experiments whether we knew it or not and have come to conclusions about certain situation

acid‚ or DNA as it is most commonly known‚ is a strand of molecules found within the cell nucleus of all living things. It is called a “genetic fingerprint” because each is dissimilar to the other and each person‚ apart from identical twins‚ has different DNA patterns. DNA testing has overthrown the way law enforcement agencies collect evidence in numerous criminal cases‚ especially rape and murder and consequently had a large impact on countless past cases.
