"Dna" Essays and Research Papers


DNA DNA, or Deoxyribonucleic Acid, is described, in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular...

Dna Extraction

Introduction DNA (Deoxyribose Nucleic Acid) is a nucleic acid that has many names, each representing the phases that it undergoes (chromosomes, chromatin, genes/alleles); it resides in the nucleus (bound by 2 *phospholipid bilayers) of almost every cell in the body (red blood cells being an exception). DNA (your genotype) is double stranded and is responsible for replicating (from 46 to 92) during Interphase, so that mitosis can make new cells, repairing and allowing for growth in the body. It is...

The structure of DNA and the effect of point mutations (25 MARKS) Deoxyribose Nucleic Acid (DNA) is a polynucleotide molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Most DNA molecules are double stranded helices, consisting of two polynucleotide strands made up of simpler molecules known as nucleotides. A nucleotide is made up of an organic nitrogenous base, a deoxyribose sugar and...

Is more DNA extracted from a strawberry or kiwi fruit?

Can you expect to extract more DNA from a strawberry or kiwi fruit? Introduction: In the experiment we were inspecting the amount of genetic materials in fruits with different numbers of chromosomes. In the experiment, we mashed up a strawberry/kiwi fruit (See appendix 1 figure 2) added extraction butter and ethanol to extract the DNA. A chromosome is a long thread-like cluster of genes in the nucleus. DNA (deoxyribonucleic acid), a self-replicating material which is present in nearly all living...
