Question

Evidence suggests that RNA arose before/after DNA (circle what applies) during evolution. The primitive cell was formed by the encapsulation of RNA in a _ RNAs that have enzymatic activity arc called _ Unlike bacteria, Archaea have _ proteins associated to their DNA. The Genomic DNA is circular in _ and _. In Bacteria and Archaca cell division happens by _. In Archaca transcriptional and translational initiation is _ type. Membrane bound organelles are only found in _ . As the size of a cell increases, its volume increases _ than its surface area? Microvilli allow cells to increase their _ . The ability of a cell to perceive and response to environmental changes is called _.

Explanation / Answer

1. RNA arose after DNA as per experimental evidences of evolution . According to the central dogma of genetics states that DNA encodes for RNA( transcription process). This is followed by translation where RNA encodes for the proteins. So as we see RNA comes into existence after DNA.
