WebIn eukaryotes, DNA replication takes place in the [Select] During (Select] , RNA polymerase reads the DNA template sequence from the [Select] ends and assembles RNA nucleotides to [Select] of the newly synthesized mRNA transcript. WebProkaryotes have fewer genes and these genes are all located on one chromosome. Groups of genes producing proteins with related functions are often organized into operons in prokaryotes but not in eukaryotes. Eukaryotes also have mRNA that must have its introns excised and the mRNA transported out of the nucleus to the ribosomes. WebDNA damage and repair Maintaining the genetic stability that an organism needs for its survival requires: 1. An extremely accurate mechanism for replicating DNA, 2.
