Document Summary

Protein sequences are typically read from amino-terminus to carboxy-terminus. When nucleotide polymerize to form a nucleic acid: a hydrogen bond forms between the sugars of one nucleotide and the phosphate of the second. Franklin and wilkins analyzed dna by bombarding dna crystals and x - rays. Their analysis yielded two numbers that sparked interest, These numbers tell us there are 10 rungs, or steps, on the dna ladder for every turn of the helix. Consists of phosphate group + a pentose sugar + nitrogenous base. C3 oh is involved in bonding with the next nucleotide. There is a strong consensus that if ribonucleotides and deoxyribonucleotid es were able to form during chemical evolution, they would be able to polymerize and form rna and dna. Contains a sugar - phosphate spine: this backbone is directional. Nucleic acids allow organisms to transfer genetic information from one generation to the next.
