PPT-GENETIC MATERIAL (DNA/RNA)

INTRODUCTION In 1865 Mendel showed that genes transmitted genetic information and in the first part of the 20 th century their patterns of transmission were studied extensively Although these classical genetic studies provided little insight into the molecular nature of genes they did demonstrate that the genetic material must perform three essential functions .
