6 wrz 2014 · The structure allows DNA to stably store and replicate genetic information through its various forms including A-DNA, B-DNA, and Z-DNA. 1. DNA is made up of deoxyribose, phosphate groups, and four nitrogenous bases (adenine, guanine, cytosine, thymine). 2.
2 mar 2012 · This document discusses the structure, properties, and functions of DNA. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts.
Deoxyribonucleic acid or DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce. These instructions are found inside every cell, and are passed down from parents to their children. DNA structure. DNA is made up of molecules called nucleotides.
5 maj 2010 · The genetic material of a cell or an organism refers to those materials found in the nucleus, mitochondria and cytoplasm, which play a fundamental role in determining the structure and nature of cell substances, and capable of self-propagating and variation. DNA contains the genetic instructions for living organisms.
Slide 1. Genetics, DNA, and Heredity. The Basics. What is DNA? It's a history book -a narrative of the journey of our species through time. It's a shop manual, with an incredibly detailed blueprint for building every human cell.
24 wrz 2018 · flow of genetic information from DNA to protein. But first, in this chapter we look closely at the structure and chemistry of DNA in order to learn how its double-helical architecture allows information to be stored, duplicated, and accessed. Each DNA strand is an alternating copolymer of phosphates and deoxyribose sugars
The document summarizes key concepts about DNA structure and function including: 1. DNA replicates in a semi-conservative manner where each new DNA molecule contains one old and one new strand. 2. DNA replication requires a DNA template, nucleotides, DNA polymerase, and energy.
