GuDViN [60]

Answer:

This question lacks options, options are: A) Heterochromatin and euchromatin

B) Uniform in the genetic information they contain

C) Separated by large sketches of repetitive DNA

D) Each void of typical protein-coding sequences of DNA

E) Void of introns.  

The correct answer is A.

Explanation:

The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.

Sometimes people do not want to change their belief in a theory because:
Ber [7]

One of my passions is keeping up with creationist (and I include Intelligent Design here) attempts to  change what science is.    They wish to supplant the reason and evidence that is the basis for good science with faith instead – specifically their faith. 

Sometimes, actually often, it can become discouraging looking at how many battles must be fought to ensure our schools continue to teach good science; listening to all the politicians expressing their ignorance of science by expressing doubts about evolution; and seeing all the letters and forum responses from those who let their religion totally blind their ability to reason and fairly judge evidence. 

For example, consider these quotes from various prominent politicians:

“There are clear indications from our people who have amazing intellectual capability that this didn’t happen by accident and a creator put this in place,”

“Now, what was his time frame and how did he create the earth that we know? I’m not going to tell you that I’ve got the answers to that,” Perry said. “I believe that we were created by this all-powerful supreme being and how we got to today versus what we look like thousands of years ago, I think there’s enough holes in the theory of evolution to, you know, say there are some holes in that theory.”  Governor and Presidential candidate Rick Perry
