DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication.

DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains‚ two in particular that compose a strain of DNA‚ are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base‚ a sugar‚ and a phosphate group make up the composition of a nucleotide. In the case of DNA‚ the four nucleotides that are found along the chain of DNA are thymine (T)

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‚

In my research of the Fibonacci Numbers‚ I have found that the Fibonacci numbers appear anywhere from leafs on plants‚ patterns of flowers‚ in fruits‚ some animals‚ even in the human body. Could this be nature’s numbering system? For those who are unfamiliar with the Fibonacci numbers they are a series of numbers discovered by Leonardo Fibonacci in the 12th century in an experiment with rabbits. The order goes as follows: 1‚ 1‚ 2‚ 3‚ 5‚ 8‚ 13‚ 21‚ 34‚ 55‚ 89‚ 144‚ 233‚ 377‚ 610 and so on. Starting

DNA is a polymer‚ which is a chemical compound or a mixture of compounds consisting of repeating structural units. These repeating structures are created through polymerization. The monomer‚ meaning one part‚ units of DNA are nucleotides. Each nucleotide consists of a five carbon sugar‚ also known as deoxyribose‚ and nitrogen containing base attached to the sugar

DNA Replication Deoxyribonucleic acid (DNA) contains the genetic instructions for the biological development of a cellular form of life including some viruses. DNA is an antiparallel double helix molecule with sugar-phosphate backbone on the outer side and nitrogen bases in the inner side. The bases are paired specifically‚ also known as complementary pairing‚ Adenine (A) with Thymine (T)‚ and Guanine (G) with Cytosine (C) by two and three hydrogen bonds‚ respectively. DNA is a long polymer
