During transcription mRNA is synthesized from a strand of DNA.
Explanation;
Transcription is the process that takes place in the nucleus of a cell, where DNA molecules acts as a primer to synthesis messenger RNA, catalyzed by the enzyme RNA polymerase.
It is the first step of expression of gene, a particular segment of DNA is copied to mRNA by RNA polymerase.
Then the mRNA is transported to the cytoplasm for the process of translation in which proteins are formed.
A Sustainable society can be defined as the one which utilizes the various available resources in a judicious and economical manner such that the resources can be retained for a longer period of time to be utilized by the future generations. Two traits of such a society are:
Follows the principle of 3Rs, that is Reduce, Reuse and Recycle. This means the society supports the reduction in overuse of resources, promotes the reuse of resources wherever possible and also supports the idea of recycling several resources to sustain the availability of fresh resources.
Tries to harness and make the best possible use of the available renewable resources. The society tries to maximally utilize the renewable resources to fulfill their needs.
A Non-sustainable society can be defined as the one which uses all the available resources extravagantly and profusely without showing any concern over the amount of the resources available for the future. Two traits of such a society are:
They tend to use the more readily available resources uncontrollably without any restriction and often not considering whether the resources are required immediately and essentially or not .
They tend to waste a lot of resources as often harnessing resources to an extent which is more than the requirement of the resources causes the wastage of the excess resource.
