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 .
