influences are negligible, and that the changing environment and the nature of the gene product primarily determine those genes which evolve most rapidly. On the other hand, map position influences on evolutionary rate could be of such great importance that they provide selection pressure for map rearrangement. Because the genome of Bacillus subtilis is replicated in sequential order from one e...
It has been recently shown by us, on the basis of crystal structure database that the flexibility of B-DNA double helices depends significantly on their base sequence. Our model building studies further indicated that the existence of bifurcated cross-strand hydrogen bonds between successive base pairs is possibly the main factor behind the sequence directed DNA flexibility. These cross-strand ...
We have evaluated codon usage bias in Drosophila histone genes and have obtained the nucleotide sequence of a 5,161-bp D. hydei histone gene repeat unit. This repeat contains genes for all five histone proteins (H1, H2a, H2b, H3, and H4) and differs from the previously reported one by a second EcoRI site. These D. hydei repeats have been aligned to each other and to the 5.0-kb (i.e., long) and ...
در قسمت اول این تحقیق، کمپلکس [fe-schiff base] با روش اشباع سازی در نانوراکتورsba-15 تثبیت شده است. این نانو کاتالیزور به وسیله تکنیک هایxrd ،tem ، bet (جذب – واجذب نیتروژن(، ir، uv و tga شناسایی شده اند. الگوی xrd و تصویر tem مربوط به [fe-schiff base/sba-15] ساختار هگزاگونال منظم را در مزوحفره های سیلیکا نشان دادند. ایزوترم جذب – واجذب نیتروژن [fe-schiff base/sba-15] بر طبق دسته بندی آیوپاک بر...
Kinetoplast DNA minicircles from various species of trypanosomes are heterogeneous in nucleotide sequence to various degrees but in all instances contain a conserved sequence region of 100 to 200 base pairs present in one, two, or four copies per minicircle. Comparison of the conserved sequence regions of minicircles from eight species of trypanosomes revealed a common sequence motif consisting...
The nucleotide sequence of the 948,061 base pairs of chromosome XVI has been determined, completing the sequence of the yeast genome. Chromosome XVI was the last yeast chromosome identified, and some of the genes mapped early to it, such as GAL4, PEP4 and RAD1 (ref. 2) have played important roles in the development of yeast biology. The architecture of this final chromosome seems to be typical ...
We investigated the genomic properties of a rotavirus A strain isolated from diarrheic pheasant poults in Hungary in 2015. Sequence analyses revealed a shared genomic constellation (G23-P[37]-I4-R4-C4-M4-A16-N10-T4-E4-H4) and close relationship (range of nucleotide sequence similarity: VP2, 88%; VP1 and NSP4, 98%) with another pheasant rotavirus strain isolated previously in Germany.
