Homework # 1 DNA 2. Name the four differences between RNA and DNA. 1) DNA is double stranded‚ RNA is single 2) DNA has Adenine‚ Guanine‚ Thiame‚ and Cytosine as nitro bases. With RNA‚ anywhere you would expect to see Thaime‚ you see Uracil instead. 3) DNA has no types‚ RNA has 3 types: mRNA‚ rRNA‚ and tRNA. 4) DNA and RNA have different sugars. 3. For the following DNS strand‚ provide the replicated strand : GATTACACATTAG CTAATGTGTAATC 4. For the following DNA sequence provide

Recombinant DNA Technology Recombinant DNA technology refers to the ability to isolate specific DNA sequences and alter or manipulate them to produce desired effects. More often‚ recombinant DNA technology is referred to as biotechnology. Recombinant DNA technology is fascinating in that it has developed into a multi-billion dollar industry‚ and completely revolutionized agriculture and pharmaceutical industries‚ all within the past 50 years. According to one account‚ biotechnology was born

Deoxyribonucleic Acid (DNA) DNA stands for deoxyribonucleic acid‚ it is located in the nuclei of cells which make up the body. DNA is quite often referred to as one of the building blocks of the body.. It is made up of four bases known as: • Adenine • Guanine • Cytosine • Thymine James Watson‚ Francis Crick‚ Maurice Wilkins‚ Rosalind Franklin Crick and Watson‚ together with Maurice Wilkins‚ won the 1962 Nobel Prize in physiology or medicine for their 1953 determination of the structure of

The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms‚ but to also educate them on how DNA can be extracted using common household materials. Also‚ the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally‚ students were instructed through a very clear and simple procedure‚ which guided

the structure of DNA. ➢ DNA is a nucleic acid‚ which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides‚ each a chain of nucleotides. Each nucleotide consists of a nitrogenous base‚ a sugar‚ and a phosphate group. Each DNA strand serves as a mold‚ or template‚ to guide reproduction of the other strand. There are four different types of nucleotides found in DNA‚ differing only in the nitrogenous base. DNA is contained in

DNA Technology: Biotechnology 1) Selective breeding a. 2) Genetic engineering – humans tinker with organisms genes a. Cloning –take haploid cel and replace with a diploid nucleus (comes from organism whos traits you want to duplicate. b. Recombinant DNA – DNA from 2 or more sources. Done by Euk cells during Meiosis. Always from same molecule. 3) Biologists first started doing recombinant DNA from a prok cell and combined it with another prok cell because it was easier. 4) DNA from a

What role does DNA play in inheritance? - DNA is the genetic material of inheritance. Deoxyribonucleic acid (DNA) is the body’s instruction manual for making who you are. DNA is present in any living being. You receive one -half of your DNA from your money and one-half from you Father. People with light eyes tend to carry recessive alleles of the major gene and people with dark eyes tend to carry the dominant alleles. Genes are located on rodlike structures called chromosomes that are found in the

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The

Recombinant DNA Technology Benefits in Many Areas Recombinant DNA Technology is a DNA-based tool that allows scientists to find individual genes‚ cut them out‚ and insert them into the genome of another organism. Recombinant DNA Technology has been used to create different types of medicines for example human insulin. People with diabetes do not produce enough insulin for their own bodies‚ and in a lot of cases‚ they are allergic to non-human insulin. Due to the creation of Recombinant DNA Technology
