`{:(A,B,C,D),("Replication"," Reverse ","Transcription","Translation" ),(,"Transription",,):}`

Solution :(c) : DNA replication refers to the porcess of formation of two similar copies of DNA using PARENTAL DNA as template. The expression of the genetic material accurs normally through the production of PROTEINS. This involves two consecutive steps. These are transcription and translation. THe DNA CODES for the production of massenger RNA (mRNA) during transcription. mRNA CARRIES coded information to ribosomes. The ribosomes read this information and use itfor protein synthesis. This process is called translation. Crick decribed this undirectional flow of information in 1958 as the central dogma of molecular biology. Many tumour VIRUSES contain RNA as genetic material and replicate by first synthesising a complementary DNA. This process is called reverse transcription (teminism). It is carried out by an RNA-dependent DNA polymerasecalled reverse transcriptase.
