DNA Transcription The process of transcription is where a copy of a gene is made within DNA to use as RNA. It is located in the nucleus of eukaryotes and in the nucleoid of prokaryotes. DNA stores information encoded in a genetic code. The code consists of four letters and they are T (thymine)‚ G (guanine)‚ A (Adenine)‚ and C (cytosine). One gene codes for on protein. RNA is a molecule that copies information that is coded in another genetic code. This code also consists of the same four

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA molecules are composed of two strands that form a helical ascending spiral. They fit together like the opposing teeth of a zipper and are held together by weak interactions called hydrogen bonds. These two strands is a long string of subunits called nucleotides‚ each attached to the one immediately about it and the one immediately below it to form a long chain. Each

Draft 5\9\10 Understanding DNA Have you ever wondered how you got red hair or blue eyes? Well all that has to do with your genes. To have different genes you have to have a deoxyriboncleic acid or DNA for short. Without Dna everyone would and everything would look the same and that would make life really confusing. Your DNA has a very important role in life. Its most important role is to give everyone character. Every Dna chromosome is made the same according to species

DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains‚ two in particular that compose a strain of DNA‚ are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base‚ a sugar‚ and a phosphate group make up the composition of a nucleotide. In the case of DNA‚ the four nucleotides that are found along the chain of DNA are thymine (T)

Roles of DNA and RNA in the Human Body and Medicine Anatomy and Physiology 1 Dr. Joy Henry Schonathan Crews 3/20/2015 Roles of DNA and RNA in the Human Body and Medicine Introduction Deoxyribonucleic acid (DNA) is the foreman of the body with a strict set of blueprints for what needs to be done in an organism’s cell and how.1 Each cell is encoded with a specific sequence of DNA which stores how it is to be made and reproduce. Ribonucleic acid (RNA) is the assistant to the foreman

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine‚ Guanine‚ Cytosine and Thymine. These bases

ions -DNA replication minimizes errors such as the DNA that is duplicated but changes in the DNA do occur‚ producing mutations. Although most mutations are either neutral or harmful they are also the raw material for evolution. Such mutations from alleles‚ alternate forms of a given gene that may produce differences in structure or function such as black‚ brown or blond hair in humans‚ or different mating calls in frogs. Stages of Mitosis~ 1)Parent cell. 2)Chromosomes make identical copies

DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands‚ pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides
