guanine

Monoalkylating agents can react only with one 7-N of guanine.

Guanine is found in integumentary system of many fish such as sturgeon.

They work by methylating guanine at the O-6 and N-7 position.

These results indicate guanine could arise in frozen regions of the primitive earth.

The guanine may produce shimmery, iridescent effects on the skin.

The fraction of guanine + cytosine pairs is 65 mole percent.

Lane G represents positions of guanines in the sequence, cut by dimethyl-sulfate-piperidine.

These agents also bind at N7 of guanine.

Second, the concentration of purines (cytosine and guanine) are also always the same.

The white dots result from cells filled with guanine, which is a byproduct of protein metabolism.

Formamide has been shown to create guanine at 130 C in the presence of ultra violet light.

The 7-nitrogen of guanine is methylated (by a methyl transferase).

However it is evident that bleomycin can interact with other sequences which do not contain guanines.

The body is scaleless and the skin covered with easily abraded, silvery guanine.

Mostly they act on the adjacent N-7 position of guanine, forming 1, 2 intrastrand crosslink.

Previously, guanine has been extracted from the scales of the bleak and used in making artificial pearls.

The guano from the nightingale has a high concentration of urea and guanine.

Alternatively, the enol (below right) and ion forms are complementary to guanine.

It is a purine analogue of the nucleobase guanine.

Guanine, the major excretory product of ticks, encouraged assembly.

They were all believed to have high guanine and cytosine content in their DNA.

About fifty years later, Fischer determined the structure and also showed that uric acid can be converted to guanine.

The guanine + cytosine ratio of Marinobacter hydrocarbonoclasticus' genome is 52.7%.

In Watson-Crick base pairing, it forms three hydrogen bonds with guanine.

Bold Gs show the guanines found to be methylated in the methylation interference analysis.
