In the previous chapter , you have lear nt the inheritance patterns and the genetic basis of such patterns. At the time of Mendel, the nature of those ‘factors’ regulating the pattern of inheritance was not clear. Over the next hundred years, the nature of the putative genetic material was investigated culminating in the realisation that DNA – deoxyribonucleic acid – is the genetic material, at least for the majority of organisms. In class XI you have learnt that nucleic acids are ... In the previous chapter, you have learnt the inheritance patterns and the genetic basis of such patterns.

In class XI you have learnt that nucleic acids are ... This process occurs in three stages: initiation, elongation and termination. DNA-dependent RNA polymerase bind at double stranded DNA at the promoter region of the template strand and initiate the process of transcription. RNA polymerase moves along DNA and leads to the unwinding of DNA duplex. One strand is called as sense strand which acts as a template for mRNA synthesis. RNA polymerase utilise dNTPs as raw material and polymerizes to form mRNA. This process continues till the enzyme ... MOLECULAR BASIS OF INHERITANCE a. both positive b. both negative c. negative and positive, respectively d. zero
