Document Summary

Holds the genetic material that is passed from parents to offspring . Acting as a template from which proteins are produced (mrna) Forming the ribosomes to synthesize proteins rrna. Carrying amino acids to the growing amino acid chain during amino acid synthesis: trna. Rna is also involved in gene regulation and processes like mrna splicing. Monomer: composed of 3 different things sugar, base, phosphate. Deoxyribonucleotides contain deoxyribose, which is like ribose except that the c2" bears two hydrogen aka the second carbon bears 2 hydrogens. Except that c2 bears 2 hydrogen atoms, instead of one hydrogen and one hydroxyl so basically for this deoxyribose you just take out the hydroxyl and replace it with another hydrogen atom . The deoxyribose on the monosacchride has 2 hydrogens. Deoxyribonucleotides contains deoxyribose and ribonucleotides contain pentose ribose. Nitrogenous bases: there are 2 types . purines and pyrimidines. These 2 nitrogenous bases are both planar and hydrophobic.
