Normally expression is always consider with the, transcription most of the regulation applied over transcriptional initiation in prokaryotes, why

#SCPH01 Biochemistry

  1. Because transcription initiation is the most energetically efficient step to regulate

  2. Regulation at this first step is easier to do well.

  3. There is only a single copy of each gene (in a haploid genome), and so typically only a single promoter on a single DNA molecule must be regulated to control expression of a given gene.

  4. A, B & C

There is still some controversy among biologists about whether Neanderthals should be placed within the same species as modern humans, or into a separate species of their own. Most DNA sequence data analyzed so far indicate that there was probably little or no gene flow between Neanderthals and Homo sapiens. Which species concept is most applicable in this example?
