The Secret Of Heredity It unlocks the mystery of the inheritance! Let us observe the truth in it! This study is about: RNA DNA

RNA Summary of RNA Transfer RNA (tRNA) is a small (65-110 nucleotides) molecule designed to carry activated amino acids to the site of protein synthesis, the ribosome. It is long-lived (stable). Ribosomal RNA (along with various proteins) forms the ribosome, the site of protein synthesis, and one rRNA is the catalyst for formation of the peptide bond (Science, June 5, 1992). Various species range in size from 4700 bases to about 120 bases. Eukaryotic and prokaryotic rRNAs are distinctly different. rRNA is also long-lived (stable). Messenger RNA (mRNA) is the carrier of genetic information on the primary structure of proteins from DNA, along with special features that allow it to attach to ribosomes and function in protein synthesis. Its size depends on the size of the protein for which it codes. It tends to be relatively short-lived, and its lifetime varies from molecular species to molecular species (depending on the biological role of the protein).

The Basics of RNA Ribo Nucleic Acids consist of: Ribose (a pentose = sugar with 5 carbons) Phosphoric Acid Organic (nitrogenous) bases: Purines (Adenine and Guanine) and Pyrimidines (Cytosine and Uracil) An RNA molecule is a linear polymer in which the monomers (nucleotides) are linked together by means of phosphodiester bridges, or bonds. These bonds link the 3' carbon in the ribose of one nucleotide to the 5' carbon in the ribose of the adjacent nucleotide.

NUCLEOTIDES & NUCLEOSIDES Definitions Bases   Adenine (A) Guanine (G) Cytosine (C) Uracyl (U) The combination of a ribose and a base constitutes a nucleoside . Adenosine Guanosine Cytidine Uridine The combination of a phosphate, a ribose and a base constitutes a nucleotide. Adenylate Guanylate Cytidylate Uridylate.

RNA The rule A+C=U+G CAN'T BE APPLIED THERE Because most RNA is single stranded and does not form a double helix. Although each RNA molecule has only a single polynucleotide chain, it is not a smooth linear structure. It has extensive regions of complementary AU, or GC pairs. Therefore, the molecule folds on itself forming structures called hairpin loops. In the base paired region, the RNA molecule adopts a helical structure as in DNA

DNA The components: The deoxyribonucleic acid, DNA, is a long chain of nucleotides. Deoxyribose (a pentose = sugar with 5 carbons) Phosphoric Acid Organic (nitrogenous) bases (Purines - Adenine and Guanine, or Pyrimidines -Cytosine and Thymine)

Basics of DNA DNA consists of two associated polynucleotide strands that wind together in a helical fashion. It is often described as a double helix. Each polynucleotide is a linear polymer in which the monomers (deoxynucleotides), are linked together by means of phosphodiester bridges , or bonds. These bonds link the 3' carbon in the ribose of one deoxynucleotide to the 5' carbon in the ribose of the adjacent deoxynucleotide.

All about DNA The human diploid cell DNA weighs 3.6 picogram(1 picogram=10^-12 g). It is 173 cm long. How ever the length and weight vary according to the place it occupies. DNA is located in the chromosome & thus chromosome forms the vehicle for hereditary transmission.
