It can base pair with complementary strands of DNA or RNA according to standard base pairing rules-G pairs with C, A pairs with U or T. The paired strands in RNA-RNA or RNA-DNA are anti parallel as in DNA.
In both DNA and RNA, heterocyclic base and phosphate ester linkages are at C1 and C5 „ respectively of the sugar molecule.
Types of RNA
1. Messanger RNA( m-RNA) It is produced in the nucleus and carries information for the synthesis of proteins.
2. Transfer RNA( Soluble or Adoptive RNA)( s-RNA, t-RNA) It is found in cytoplasm. Its function-is to collect amino acids from cytoplasm for protein synthesis.
Functions of Nucleic Acids 1. Direct the synthesis of proteins. 2. Transfer the genetic information( hereditary characters).
Replication It is a process in which a molecule of DNA can duplicate.
Template It means pattern. In the process of replication of DNA, the parent strand serves as template.
Gene The portion of DNA carrying information about a specific protein is Called gene.
