structure of a nucleotide One type of nucleic acid is the ribonucleic acid (RNA). The RNA is single-stranded used for the coding of the primary sequence of amino acids to make proteins‚ and is found mainly in the cytoplasm. In terms of structure‚ its distinguishing characteristic is that‚ from its name‚ ribonucleic acid indicates the presence of ribose‚ a cyclic monosaccharide with an aldehyde functional group. Furthermore‚ RNA can also be differentiated from other nucleic acids in terms of organic or

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 letters as in DNA yet with U (uracil)‚ which is a substitute for T (thymine). RNA is a single strand

DNA Worksheet Trisha McCabe SCI/230 May 8th 20132 Chandreyi Basu‚ PhD Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA made up of units called nucleotides‚ nucleotides are made up of three molecules components‚ a nitrogen base‚ a sugar‚ and a phosphate (Simon‚ Reece‚ Dickey‚ 2010). The nucleotides are joined together by bonds between the sugar of one nucleotide and the phosphate of the next producing

FRQ #3 a) The flow of genetic information from DNA to protein in eukaryotic cells is called the central dogma of biology. The role of RNA in protein synthesis is extremely important as protein synthesis could not occur without RNA. Three forms of RNA exist solely to create proteins. Through a process known as translation‚ RNA constructs the proteins necessary to sustain life. Spliceosomes Process pre-mRNA by splicing out intronic nucleic acids producing mRNA which is then translated to protein

very stable‚ the genetic material is RNA and replication takes place one of two ways; with heat that denatures the RNA or with an enzyme called a ribozyme. The atmospheric conditions on the early Earth may have played an important role in the formation of components of nucleic acids that make up genetic material‚ including the sugar ribose and the four nucleobases. Scientists have shown that clays such as montmorillonite are able to catalyze polymers of RNA from single nucleotides. These clays

In the leading strand‚ RNA Primase moves along nucleotides and coats with a RNA Primer that will be used as a homing beacon for the DNA Polymerase. h. DNA polymerase synthesizes the new DNA by adding complementary nucleotides to the template strand. i. DNA polymerase attaches post primase to DNA nucleotides

well as identify the principle involved in each chemical test. Different procedures and different test compounds were applied‚ and results were noted as for changes in colors of precipitates or solutions. For Dische Test‚ light blue was obtained for RNA and dark violet for DNA. For Murexide Test‚ a yellow layer was obtained with a mixture of red color and eventually became yellow or orange after addition of warm water. For John-Wheeler Test‚ a violet precipitate was obtained and lastly for Phosphate
