Molecular Genetics

nucleotides are the monomers of DNA RNA Nucleotide [pic] The left picture shows the nucleotide unit of RNA. Nucleotides differ from nucleosides in that they have phosphate groups. Nucleotides can exist in the mono-, di-, or tri-phosphorylated forms. The most common site of phosphorylation of nucleotides found in cells is the hydroxyl group attached to the 5'-carbon of the ribose. Nucleotide units line up forming the backbone of RNA / DNA. 1A. Typical DNA Molecule ...

Central Dogma of Molecular Biology

and computer Sciences, De La Salle University-Dasmarinas ABSTRACT: The central dogma of biology holds that genetic information normally flows from DNA to RNA to protein. In the experiment, DNA and RNA bead kits were used. Different coloured beads correspond to different nitrogenous bases, sugars and phosphates. Different structures of DNA and RNA were formed based on the sequences that were given. INTRODUCTION: DNA contains the complete genetic information that defines the structure and function...

Recognize the guanine and uridine rich single stranded RNAs) viii. TLR 9: unmethlylated CpG DNA (vaccinia, hepB, herpes) 2. Both single and dsDNA b. Many DNA viruses transcribe both strands of certain regions of their DNA genomes = self- complementary RNAs (dsRNA) c. ssRNA viruses = replicate their genome by synthesizing full length complementary RNA stands that can form dsRNA by hybridizing to the template RNA strand ix. ***The presence of dsRNA is the...

What does it mean when scientists say that living organisms share a universal genetic code? 2. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? 3. How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth? 4. How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely...

Macromolecules

one single sugar molecule. A simple sugar can have a carbon backbone of three to seven carbons. Glucose, with six carbon atoms, is a hexose (Mader, 2010). Ribose and deoxyribose, both with five carbon atoms, are pentoses and are also found in RNA and DNA. A disaccharide contains two monosaccharides that have joined together during a dehydration reaction. Sucrose is a disaccharide of distinction because it’s the basic sugar we use at home as table sugar (Mader, 2010). Lactose is the disaccharide...

DNA Work Sheet

corresponding genes are transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport). Outside the nucleus, the proteins are built based upon the code in the RNA (translation). Transcription is the process by which the information contained in a section of DNA is transferred to a newly assembled piece of messenger RNA (mRNA). It is facilitated by RNA polymerase and transcription factors. In...

cell membrane by removing its cellular macromolecules including proteins, lipids and nucleic acids allowing extraction of the DNA from the nucleus (Leonard, 2007). b) RNaseA RNase A is a solution that contains RNase enzymes which breaks down the RNA present in the solution into small fragments of ribonucleosides (Rether et al., 1993) while keeping the DNA intact. RNase specifically attacks pyrimidine nucleotides by cleaving the phosphodiester bond 5'-ribose of a nucleotide and the phosphate group...

The Central Dogma

flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA, and RNA from RNA). RNA can be made or transcribed from DNA. It is called transcription since the same type of "language" is used in DNA and RNA -- i.e. nucleic acids. In some cases RNA may be used to make DNA (i.e. "reverse transcription") using a particular enzyme called reverse transcriptase. Protein is synthesized from RNA by translation. It is called translation, because...

several words, for example WHO from the initial letters of World Health Organization. What do the acronyms DNA and RNA stand for? DNA stands for deoxyribonucleic acid. RNA stands for ribonuncleic acid. 17 What are the four kinds of nucleotides: a in DNA The four kinds of nucleotides in DNA are adenine (A), thymine (T), cytosine (C) and guanine (G). b in RNA? The four kinds of nucleotides in RNA are adenine (A), uracil (U), cytosine (C) and guanine (G). 18 Where in a cell would you find DNA and what is...
