In complementary base pairing, the G pairs with C, and A pairs with T. Given that this be the rule, the complementary nucleotides for your sequence would be as follows: CGATTAACGTAGGCA.
With regards to proofreading, mutations in cell division occur once in around every 100,000 base pairs. If this happens, the enzyme that pairs the nucleotides to form DNA, called DNA polymerase, detects the error and moves back along the strand, it then cuts the incorrect nucleotide and replaces it with the correct one, fixing the error and continuing with the DNA synthesis.
This process corrects the majority of errors in DNA synthesis, but some errors can still be missed by the DNA polymerase, this is then rectified by a protein complex which binds to the incorrect pairing until anther complex, comes along and cuts that particular section of DNA out, which is then replaced by a new section of correct nucleotides synthesized by the polymerase enzyme, the two sections at either end that were cut is then sealed by ligase, an enzyme which essentially "glues" the DNA stands back together.
My apologies for the long answer, I hope I answered your question and that you understand it well enough.
Answer:
central vacuole
Explanation:
In many plant cells there is a single large central vacuole filled with liquid, pressure of the central vacuole allows plants to support heavy structures such as leaves and flowers. pro here here :D
<span>Covered by the two cerebral hemispheres, the diencephalon is
the structure of the central nervous system that surrounds the third ventricle.
It is composed of several other structures. The most important of them are the
Thalamus, which plays a very important role in movements and emotions; and the
Hypothalamus, which provides functions including thermoregulation, appetite and
regulation of the sleep-wake cycle.</span>
The statement is once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accommodate the product.
With the capabilities the Space Shuttle provides, scientist now have the means for deploying these observatories from the Shuttle's cargo bay directly into orbit. NASA's Hubble Space Telescope, the first of the great observatories, was deployed from the Space Shuttle Discovery into Earth orbit in April 1990.
