Presentation on theme: "D.N.A. DeoxyriboNucleic Acid"— Presentation transcript:
1 D.N.A. DeoxyriboNucleic Acid A molecule that contains our genetic informationIs found in the nucleus of almost all cells wound up into chromosomes.
2 DeoxyriboNucleic Acid Double Helix (Twisted Ladder)Double strandedMade of Nucleotides: Sugar, Phosphate, BaseHas 4 nitrogen bases: Adenine, Guanine, Thymine, CytosineCombination of these bases (order) is what makes up our traits
11 RNA Ribonucleic acid RNA is a messenger for DNA. RNA takes the genetic information from DNA and takes it to the ribosomes where it makes the proteins
12 3 differences between RNA and DNA 1. RNA = ribose (does have oxygen)DNA – deoxyribose (does not have oxygen)2. RNA has a single strandDNA has a double strand3. RNA has uracil as a base instead of Thymine like DNA has2
13 RNA 3 types messenger RNA – takes info from nucleus to ribosome transfer RNA – transfers amino acids to ribosomeRibosomal RNA – makes up ribosomes
