Question

Explain the basic parts of a major theme molecular biology: the pathway of DNA to RNA to Proteins. Inculed a grneral idea of what occurs at each stage.

Answer 1

1st step: Transcription DNA is unraveled and used as a template to form complimentary mRNA mRNA then leaves nucleus in order to attach to ribosome and start 2nd step. 2nd step: Translation tRNA with aminoacids attached will try to join mRNA\ribosome complex if tRNA triple codon matches the mRNA code it will attach aminoacid to start forming protein. This process continues until mRNA reaches STOP code, resulting in a long chain of aminoacids. 3rd step: Protein folding and modification Usually performed by chaperonins and eventually golgi complex. Chaperonins assist in proper protein folding, while golgi apparatus performs final modifications.
