Molecular basis of inheritance – cbse notes for class 12 biology ncert solutions maths physics chemistry biology science the dna and rna world: 1 over the years after mendel, the nature of the genetic material was investigated, resulting in the realisation that dna is the genetic material in majority of organisms 2 deoxyribonucleic acid (dna) and ribonucleic acid (rna) are the two types. Biology molecular basis of inheritance part 1 (introduction, dna, rna) class 12 xii.
Molecular basis of inheritance genetics mainly deals with the study of genes, heredity, and genetic variation genes exist on chromosomes and chromosomes are comprised of dna and proteins. Chapter 16: the molecular basis of inheritance study guide by mreardon13 includes 58 questions covering vocabulary, terms and more quizlet flashcards, activities and games help you improve your grades. Each nucleotide monomer consists of a nitrogenous base (t, a, c, or g), the sugar deoxyribose, and a phosphate group the phosphate of one nucleotide is attached to the sugar of the next, resulting in a “backbone” of alternating phosphates and sugars from which the bases project. The basis for these rules remained unexplained until the discovery of the double helix watson and crick discovered the double helix by building models to conform to x-ray data by the early 1950s, the challenge was to determine how the structure of dna accounted for.
Structure of dna: watson and crick proposed a double helical model for dna, based on x-ray crystallography of the molecule each strand (helix) is a polymer of nucleotides, each nucleotide consisting of a deoxyribose sugar, a nitrogen base and a phosphate.
