    Extracting DNA from Wheat Germ Cells Criteria to be assessed CE Introduction: DNA is the abbreviation for deoxyribonucleic acid. DNA is found in the nucleus of every cell & it stores the information that makes up living organisms. It is a double helix of 4 nucleotides. It contains a code that allows the body to make up proteins. The nucleotides are Cytosine‚ Guanine‚ Adenine and Thymine. (1) Wheat germ comes from wheat seeds. The ’ germ ’ is the embryo‚ which is the part of

    The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms‚ but to also educate them on how DNA can be extracted using common household materials. Also‚ the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally‚ students were instructed through a very clear and simple procedure‚ which guided

    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 base. DNA is contained in

    DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively

    DNA Turns Into Polyptide

    • 276 Words
    • 2 Pages

    process by which DNA turns into polypeptides is a complicated and long. Two main steps in changing the DNA into a polypeptide are transcription and translation‚ with transcription coming first. The process first starts in the nucleus of the cell. The DNA begins to unfold with the help of a helicase. During the transcription phase of the change‚ strands of DNA begin to unwind and the complementary mRNA is made or transcribed. The way they do this is by using the common pairs of DNA triplet bases (A-T

    The Advantages of DNA Replication DNA stands for Deoxyribonucleic acid‚ and it is found in the nucleus of every cell in the human body. DNA is the master plan - it contains all the genetic information needed for a living thing to develop and function. Each and every single organism has a unique and different DNA encoding. DNA’s purpose is to store all of our genetic information similar to the way a builders blue print sets out the design of a house. Without DNA there would be no such thing as
