Compare and Contrast Dna and Rna

Ch. 12 & 13 DNA & Protein Synthesis Project By Anthony Li, Connor Farrell, John Koutsonikolis, and Tristan Funicelli (Tristan) # Describe the contributions of each of the following to the discovery of the structure of DNA - 1) Watson and Crick: Used Rosalind Franklin’s x-rays of DNA to conclude that DNA took the shape of a double helix. 2) Frederick Miescher: Used pus from infections to isolate nuclein. He found that nuclein had a unique ratio of phosphorous to nitrogen. 3) Oswald Avery: Tested

Compare and contrast DNA and RNA? DNA and RNA have some similarities they both are polymer of nucleotides. Its sugar is connected to group at one end and a nitrogenos base at the other end. DNA and RNA also can be located in the nucleus. DNA stays in the nucleus while RNA can move in and out of the nucleus. The difference between DNA and RNA is DNA is double stranded and RNA is single stranded. DNA has deoxyribose sugar and RNA has ribose sugar. DNA also has thymine and RNA has uracil. DNA can undergo

DNA: Structure and Replication 1. Describe and compare the chemical compositions of DNA and RNA. DNA and RNA are nucleic acids; they are characterized by being long chains that are called polymers, from other units called nucleotides. With the DNA and RNA, it is expected to have a variety of polynucleotide chains. The nucleotides are intertwined by means of covalent bonds between sugar of a nucleotide and the phosphate of the next. This results in an ordered backbone pattern. As well as the DNA

and eukaryotic cells is their DNA. Thus, these two cells have different features on DNA transcription and protein synthesis mechanisms. The general processes of transcription may be applied to both prokaryotic and eukaryotic cells as their basic biochemistry was the same. But, they are differs in their specific mechanisms and regulation of transcriptions. In all species, the process of transcriptions begins with the binding of RNA polymerase complex to a special DNA sequence at the beginning of the

different chromosomes. Explain how these alleles are transmitted by the process of mitosis to daughter cells. After mitosis the parent cell's genome is dividedninto two daughter cells. In most eukaryotes, the nuclear envelope that separates the DNA from the cytoplasm disassembles. The chromosomes align themselves in a line spanning the cell. As the cell elongates, corresponding sister chromosomes are pulled toward opposite ends. A new nuclear envelope forms around the separated sister chromosomes

1. Compare and contrast prokaryotic and eukaryotic cells. Be sure to address cell structure, replication (including DNA replication) and gene expression. The cell structure of prokaryotic organisms is small, only about 1-10 microns in length, and they are also single celled. Prokaryotes contain circular DNA which is held in the nucleoid because they lack a nucleus. The specific organisms that have circular DNA are: mitochondrial, bacterial (eubacteria), and Archaea (Methanobacteria, Halobacteria

Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokaryotes is also defined by the Oxford dictionary as an organism that does not contain a ‘distinct nucleus with a membrane’. These two terms highlighted a very important difference between the two cells; eukaryotic cells had a true nucleus surrounded by a membrane but the prokaryotes did not. The following essay seeks to compare and contrast typical prokaryotic cells to typical

her milk. Gene transfer is defined as 'the insertion of copies into a gene into living cells in order to induce synthesis of the gene's product..'2 Describe the process and techniques involved in the genetic modification of an existing gene by RNA interference (gene knockdown) Gene knockdown is when the 'mRNA product of a gene is targeted and disrupted so it can't carry out it's normal function.'3 The process of

genomes will provide a better understanding for such diversity. ‘karyote’ refers to the nucleus, and also ‘pro’ means ‘absence’ and ‘eu’ means ‘presence’. Therefore the words prokaryote and eukaryote reflect upon the individual cell organization. In contrast, the both organizations
