Nucleotide: a nucleic acid monomer, consisting of five carbon sugar covalently bonded to nitrogenous base and phosphate group. DNA “backbone” : chain nucleotide made of sugar and phosphate group that are joined together by covalent bond and are resistant to cleavage Antiparallel: the 2 strands of DNA double helix that run in opposite directions of each other Reactive chemical group at the 5’ end of DNA: phosphate group Reactive chemical group at the 3’ end of DNA : hydroxyl group The four DNA nucleobases thymine (T), adenine (A), Cytosine (C) and guanine (G) , Complementary base pairing adenine and thymine pair (A-T) and guanine and cytosine pair (G-C) Melting temperature: temperature needed to break 50% of the hydrogen bonds Chromatin:…
According to http://www.encyclopedia.com, DNA which stands for deoxyribonucleic acid is used for human genetic makeup. It has different sequences of bases and exist in human body. The sequence of it nucleotides are A, T, G, C; or, adenine, thymine, guanine, and cytosine, respectively. A DNA fingerprinting, is a DNA pattern that has a unique sequence such that it can be distinguished from the DNA patterns of other individual.…
Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and phosphate molecule.…
(Arizona State University) This type of DNA is often found in bacteria, specifically E. coli. The lab group used E. coli as the test organism for this experiment,…
The name “GATTACA” is composed entirely of the letters found in the biological macromolecule DNA. DNA is made up of four letters: G (Guanine), A (Adenine), T (Thymine), and C (Cytosine). The letters are arranged in the molecule in a very specific way, with A only reacting with T (and vice versa) and G only reacting with C (and vice versa). The biological structure in Jerome’s apartment resembles a DNA strand, also known as a double helix.…
1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases.…
The role of nucleic acids are to store, express, and transmit genetic information. A nucleotide is an organic molecule having three components: one or more phosphate groups, a five carbon sugar, and a single or double ring of carbon and nitrogen atoms. Two types of nucleic acids are DNA and RNA. RNA. The structure of DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.…

The gene has a very important location in the nucleus of our cells, where it binds directly to DNA. When DNA is…
A. Purpose: The purpose of this particular experiment is to see what DNA looks like on a macroscopic scale by extracting DNA from peas. According to the Exploring Creation With Biology 2nd Edition, DNA is short for deoxyribonucleic acid, which is necessary to meet the four crieteria for life. DNA preforms many functions throughout an organism, but its main purpose lies in telling the cell which proteins to make (Wile, Durnell).…
What is DNA? DNA stands for deoxyribonucleic acid. DNA is in all living things. Most cells in the human body have the same DNA inside of their cells. Most DNA is at the nucleus of a cell.…
Construction of DNA, RNA, And Protein By Building Models Introduction Nucleic acids are made of nucleotides. When these nucleic acids form sequences they create either DNA or RNA. DNA and RNA are composed of a phosphate, a sugar, and a nitrogen base. The main difference in RNA and DNA is that uracil replaces the base of thymine in RNA. Proteins are essential to maintaining cells by creating hormones and enzymes, and defending the cell.…
Adnane Harbouche Developmental Psychology Februrary 6, 2015 Critical Thinking Paper 1 DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a persons body has the same DNA. Most DNA is located in the cell nucleus ( where it is called nuclear DNA) but a small amount of DNA can also be found in the mitochondria (where it is called Mitochondria DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: Adenine (A), guanine (G), cystoine (C) and Thymine (T).…
The DNA (also known as Deoxyribonucleic acid) in cells is formed of two long strands that wrap around each other. There are four different types of bases in DNA, A (adenine), C (cytosine), G (guanine), T (thymine). These bases join together, A with T and U with G, to form a structure that looks like the twisted steps of a…
Individuals are very unique and complicated to understand, and DNA is what makes individuals who they are. It is the code for our physical being, such as appearance, personality, and even…
