    811 Words  | 4 Pages

    1a. Review: Describe three main differences between RNA and DNA. The three main differences between RNA and DNA are as follows: RNA has the sugar ribose instead of deoxyribose, which DNA has, RNA is single-stranded while DNA is double-stranded, and RNA uses uracil instead of thymine. 1b. Explain: List the three types of RNA, and explain what they do. The three types of RNA are mRNA, tRNA, and rRNA. mRNA carries the instructions to create proteins from DNA in the nucleus to ribosomes. rRNA forms a

  • Essay On Helical Structure

    2085 Words  | 9 Pages

    DETAILED STRUCTURE OF A DOUBLE HELICAL DNA. A DNA molecule consists of a double helical structure made up of two strands running in opposite directions and twisted around each other. The helical structure of a DNA molecule is similar to the structure a corkscrew or a spring. Running in opposite directions meant that the DNA strands are anti-parallel to each other where one strand has 3’ end at its terminal while the other strand has 5’ end at its terminal. 5’ and 3’ indicates the carbon numbers in

    sequences are defined as points where the rate of addition of the next RNA nucleotide is slower than the rate of nucleotide release. Rho Factor (ρ) Introduction Rho (Greek lettering - ρ) factor is an essential prokaryotic protein. Rho forms a hexameric ring structure with an open configuration. It contains six subunit laterally organised with a distance of 12 Angstroms at the opening. This is to accommodate the single stranded RNA molecule. In E. coli, Rho is a 274.6 kD hexamer with identical subunits

Chromatin is a complex of the DNA and the cellular histone protein cores forming eukaryotic chromosomes. Structurally, the nucleosome core particle comprises 1.6 left-handed superhelical turns of DNA wound around a protein complex called the histone octamer, which consists of 2 copies each

  • Advantages Of Aptamers

    732 Words  | 3 Pages

    Aptamers are chemically synthesized single stranded DNA or RNA sequences, ranging from 20 till 100 oligonucleotides. The term aptamer is derived from the Latin aptus, meaning ‘to fit,’ and the Greek meros, meaning ‘region’ [4]. Aptamers can be developed against a variety of targets for example, metal ions, proteins, cells, viruses and antibiotics. Because of their rather short structure they form stems, hairpins, loops and quadruplexes. These tertiary folding structures gives them an unique three-dimensional

  • Polymerase Chain Reaction Case Study

    1219 Words  | 5 Pages

    1.Polymerase chain reaction (PCR): Polymerase chain reaction is a method of DNA or RNA amplification . The PCR method allows millions of copies to be created from a very small DNA section. The PCR methodology was developed in 1983 by Kary Mull , who in 1993 received a Nobel Prize for Chemistry with Michael Smith PRINCIPLE & PROCEDURES: 1.DNA denaturation. Once the DNA has been isolated and purified from the cell, a PCR assay can begin. Uncleaned DNA can also be used for PCR, but it is ineffective

  • The Importance Of Nucleotides

    1096 Words  | 5 Pages

    Nucleotides are the energy currency in a metabolic transaction. Nucleotides are the organic molecules that serves as the monomer units or building blocks of nucleic acids (the basic structural unit of nucleic acid) like DNA and RNA. Nucleotides consist of sugar, nitrogenous base, and phosphate. The nitrogenous bases found in nucleotides include adenine (purine), guanine(purine), thymine (pyrimidine), cytosine (pyrimidine), and uracil (pyrimidine). The bases adenine, guanine, and cytosine are found

  • Essay On Chloroplast Genome

    1107 Words  | 5 Pages

    INTRODUCTION Genome is the sum total of all genetic material of an organism. The genome may be either DNA or RNA. Eukaryotes and prokaryotes always have a DNA genome but viruses may either have a DNA genome or RNA genome. There are two distinct parts in eukaryotic genome, one is the nuclear genome and the other is the organelle genome, which is of two types: mitochondrial and chloroplast genome respectively. This paper focuses on the organelle genome of eukaryotes, that is, mitochondrial and chloroplast

    1525 Words  | 7 Pages

    INTRODUCTION Deoxyribonucleic acid (DNA) is a double helix structure strand which contain hereditary genetic material of living organisms. It is composed of small single nucleotides which makes a long polymer by repeating the nucleotide units. (Saender W, 1984) The nucleotide contains deoxyribose sugar, nitrogen-containing nucleotide and phosphate group which makes the DNA negative charge. In order to further study on human genomic material, the isolation and extraction of DNA is necessary to

  • The Pros And Cons Of Recombinant DNA

    1486 Words  | 6 Pages

    Recombinant DNA molecules are DNA molecules formed by laboratory methods of genetic recombination to bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure. They differ only in the nucleotide sequence within that identical overall structure.Recombinant DNA is the general name for a piece of DNA that has been created by the combination

  • Chromosomal Theory Of Inheritance Essay

    1772 Words  | 8 Pages

    The chromosomal theory of inheritance proposed by Boveri and Sutton in 1902 states that chromosomes are the physical structures that are responsible for the transmission of hereditary characters through successive generations of all organisms. Chromosomes are the structures that store and transfer genetic material from one generation to the next. They are most often found as long, thread-like structures located within the nucleus and their main function is to carry hereditary information. Recombination

  • Importance Of Gene Mapping

    856 Words  | 4 Pages

    Gene mapping can be described as the method of determining the genes and their positions on a chromosome. There are two steps in gene mapping. The first one is finding the positions of genes on chromosomes, and the second is determining the distance between these genes. The distance between two genes is given in map units, which is also called recombination units. 1 map unit is equal to 1 cM (centimorgan). But it is important to remember that centimorgan is not an actual distance, it is more like

  • Why Did Scientists Discover Antibiotics

    1396 Words  | 6 Pages

    There are many types of antibiotics [3], and I will write about some of them. Some antibiotics enter the body immediately and attack the DNA in the bacteria. As we know, every organism has cells, and one of the most important in these cells is DNA, because it controls everything inside the cell, so it will be very effective in attacking DNA inside the cells. After that, the bacteria can not survive, so we will have gotten rid of it. In this situation, we have two ways to attack DNA. One of them
