When we see pictures of chromosomes ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein structures that are sometimes depicted as ...

This means that one strand's sugar-phosphate chain runs in ... used a process called X-ray diffraction to capture images of DNA molecules (Figure 5). Although the black lines in these photos ...

The King's team took an experimental approach, looking particularly at x-ray diffraction images of DNA ... Watson and Crick showed that each strand of the DNA molecule was a template for the ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...

DSBs can be repaired using several different mechanisms. Both ends can be simply rejoined with little or no further processing (nonhomologous end joining, or NHEJ) or can be repaired using ...
