Ribonucleic acid (RNA) is a ubiquitous family of large biological molecules that perform multiple vital roles in the coding, decoding, regulation, and expression of genes. Together with DNA, RNA comprises the nucleic acids, which, along with proteins, constitute the three major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but is usually single-stranded. Cellular organisms use messenger RNA (mRNA) to convey genetic information (often notated...

Hypothesis: The Plausibility Of The RNA World Hypothesis

catalytic RNA – which was instrumental for the RNA World Hypothesis ("Sidney Altman: The RNA World"). This hypothesis stated that early life started with RNA as they possess the ability to serve as a catalyst as well as contain genetic information. The RNA was able to spontaneously form under natural processes, which eventually replicated into all sorts of life. This paper will analyze the theoretical and experimental support for this hypothesis and comment on the plausibility of the RNA World Hypothesis...

Dna and Rna

General Biology DNA and RNA Deoxyribonucleic Acid and Ribonucleic Acid • DNA is deoxyribonucleic acid. It is located in the nuclei of cells, which make up the body. Consequently, DNA can be considered as one of the building blocks of the body. Where is DNA found? DNA, or deoxyribonucleic acid, is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA. However...

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...

More About Rna

Ribonucleic acid is popularly known as RNA. RNA is one of the three major macromolecules (along with DNA and proteins) that are essential for all known forms of life. RNA stands for ribonucleic acid. It is an important molecule with long chains of nucleotides. A nucleotide contains a nitrogenous base, a ribose sugar, and a phosphate. Just like DNA, RNA is vital for living beings. The main job of RNA is to transfer the genetic code need for the creation of proteins from the nucleus to the ribosome...

interacts with Thymine, while Cytosine interacts with Guanine. RNA -RNA, also known as ribonucleic acid, is single-stranded. -An RNA nucleotide is structurally similar to that of a DNA nucleotide, but it contains a ribose sugar instead of a deoxyribose sugar. -In addition, RNA has the nucleotides Adenine, Cytosine, Guanine and Uracil. Thymine is NOT present in RNA. -Adenine pairs with Uracil, while Cytosine pairs with Guanine. -RNA is usually used as a “temporary molecule”, meaning that it is usually...

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 ...

Ebola Virus What Type Of Virus Is It

Ebola genome is a single-stranded RNA approximately 19,000 nucleotides long. It encodes seven structural proteins such as nucleoprotein, polymerase cofactor, transcription activator, RNA- dependent RNA polymerase. The Ebola virus is a Filovirus. These virus types cause fever or cause bleeding inside and outside the body when having a very high fever. Ebola can be further divided into subtypes that are named for the location they were identified. Ebola carries a RNA genome that are cylindrical, contains...
