Introduction Replication and transcription are two different biological processes necessary for the growth and survival of living organisms. Despite the same starting substrate of both processes, DNA (the messenger of genetic information) in both processes yields separate end products. Replication is known to transfer the entire genetic information to its ... Read More

Introduction All living organisms possess organs and organelles. It is most important structurally, biologically, and functionally. There are several types of organs are present in the human body to do specific functions. Basically, organs are the collection of tissues. In advanced animals, organs are grouped into an organ system. Organelles ... Read More

Introduction All living organisms need to be provided with essential nutrients, O and other important substances and other harmful substances should be continuously removed from the body. This is achieved with the help of the circulatory system present in almost all multicellular organisms. Mostly two types of circulatory systems exist ... Read More
