Also, in eukaryotic systems, the coding regions of DNA are separated by large noncoding regions ("dummy code", probably to protect the coding regions). If we were to go directly from DNA to proteins, we would get huge, completely functionless proteins. Only through transcription and splici...

Maybe what's confusing you is how the polymerase "stops" replication of the desired fragment. Well.. _____________________________ _____________________________ if this is your double-stranded DNA from which you want to isolate a specific fragment, you'd first denature, so that the strands...

The method was x-ray crystallography, and it was performed by Rosalind Franklin. Without her pictures, Watson and Crick would not have been able to determine the double helical structure of DNA

Members of the group Bacteria are indeed not found in several harsh environments on earth. For example, members of the Bacteria group are rarely found thriving in glaciers, salt, or near hydrothermal vents. However, several Archaeans are known to prefer such environments.

First of all, which system are you asking about: eukaryotic or prokaryotic? And secondly, if you could phrase your question more clearly, it might be easier to answer... :) thanks!

"Gene" refers to the region of DNA coding for a specific characteristic - a locus on a chromosome. "Allele" refers to a specific VERSION of that gene. For example, for simplicity's sake, I will say there is one gene for hair color. However, people can have brown, blond, red, etc ...
