NUCLEOTIDES, NUCLEIC ACID, AND HEREDITY Nucleotides are the building blocks (monomer) of nucleic acids. Nucleic acid is a polymer composed of nucleotides Heredity is the transfer of characteristics, anatomical as well as biochemical, from generation to generation.

SEJARAH PENEMUAN ASAM NUKLEAT 1879, Albrecht Kossel menemukan asam nukleat yang tersusun oleh suatu gugus gula, gugus fosfat, dan gugus basa

Structure of Cell

Degradation of nucleic acid Nucleoprotein Nucleic acid Protein Nuclease Nucleotide Nucleotidase Phosphate Nucleoside Nucleosidase Base Ribose

Nucleus (Inti sel) Setiap sel makhluk hidup mempunyai nucleus (inti sel) dimana didalamnya terdapat nucleoplasma Nucleus berperan dalam: Menyimpan informasi genetik Duplikasi DNA Transkripsi  dalam sintesis protein

Nucleic Acids (Asam nukleat) Dalam tubuh setiap makhluk hidup mengandung asam nukleat. Merupakan makromolekul. Bentuknya bisa berupa DNA (deoxyribonucleic acid) dan RNA (ribonucleic acid). Beberapa organisme bersel tunggal seperti virus tubuhnya hanya terdiri dari DNA atau RNA saja.

Structure of nucleotides Know this! Below is the general structure of a nucleotide. The pentose sugar, the base, and the phosphate moieties all show variations among nucleotides.

Pyrimidine and purine Nucleotide bases in nucleic acids are pyrimidines or purines. Know these!

Major bases in nucleic acids Know these! The bases are abbreviated by their first letters (A, G, C, T, U). The purines (A, G) occur in both RNA and DNA Among the pyrimidines, C occurs in both RNA and DNA, but T occurs in DNA, and U occurs in RNA

GULA RIBOSA Gula pada asam nukleat adalah ribosa. Ribosa (b-D-furanosa) adalah gula pentosa (jumlah karbon 5). Perhatikan penomoran. Dalam penulisan diberi tanda prime(') untuk membedakan penomoran pada basa nitrogen 5 1 2 3 4

PERHATIKAN Ikatan gula ribosa dengan basa nitrogen (pada atom karbon nomor 1). Ikatan gula ribosa dengan gugus fosfat (pada atom karbon nomor 5). Gugus hidroksil pada atom karbon nomor 2

Structure of nucleotides Nucleotides have three characteristic components: A nitrogenous base (pyrimidines or purine) A phosphate group A pentose sugar

Structure of nucleosides Remove the phosphate group, and you have a nucleoside. H
