1. It can replicate because the specificity of base pairing ensures that the daughter molecules are identical to the original one.

2. There are approximately 10 9 base pairs in the human chromosome set.

3. Genes differ in length, averaging about 10 3 base pairs.

4. Conclusion Though 30 base pair deletion of Epstein-Barr virus LMP1 may not be an important pathogenetic step in extranodal nasal type NK/T-cell lymphoma, it may play some role in tumor progression.

5. A hot spot is a DNA base pair (the individual units of DNA) that is especially prone to mutation.

5. Sentencedict.com try its best to collect and make good sentences.

6. Strictly, a base pair is a pair of complementary bases (i.e. the A:T, G:C and A:U interactions) held together by hydrogen bonds.

7. They sequenced a 368 base pair fragment from the mitochrondrial genome and then compared it to sequences from ancient dogs, as well as to sequences from modern dogs, wolves, and coyotes.

8. The core consists of 140 base pair of DNA wrapped around a globular histone bead containing two each of histones H2A, H2B, H3 and H4.

9. The base pair ratio, AT : GC , is constant within a species but differs between species.

10. The repressor also recognizes sequence-dependent distortion or flexibility of the operator phosphate backbone, conferring specificity even for inaccessible base pairs.

11. In the formation of the double helix, a total of 12 rotors are restricted per base pair stack.

12. It is probably that the conjugated plane of gossypol is inserted into the base pair pleated sheet of the DNA double helical structure to associate with thymine through weak polar bond.

13. So, in the case of neuroepithelial neoplasia, he said[Sentencedict.com], they are looking for mutations outside of the 12 base pair segment of the gene.

14. In Ames assay the strains were TA98 and TA100, which were able to determine base pair substitutions and frameshift mutation respectively.

15. A simple solution would be to switch to the Google approach -- for every base pair "word," make a list of the genes where they appear.

16. In the end, the effects of methylation on the properties of uracil and adenine-uracil base pair have been investigated.

17. Researchers have also advocated assessing health risks within ethnic groups based on inherited variations in just one DNA base pair.

18. He found a remarkably steady decline, from over $10 per base pair to, lately, well under $1 (see chart).

19. These steps include specific cutting of DNA at defined sites, joining or splicing of DNA fragments, and numerous other modifications which allow manipulation down to the level of a single base pair.

20. DNA footprinting utilizes a DNA damaging agent (either a chemical reagent or a nuclease) which cleaves DNA at every base pair.

21. Sequencing DNA has come down in price by half annually, from $10 per base pair in 1990 to under a penny today.

22. Actually it is not enough of doing that, the complementary base pair can link together, but just combining the treadles of a ladder broken in two parts that cluff of handrails is left broken.

23. The empirical rules, which take into account the non neighbor interactions between the base pair steps, have been presented to predict the local bending of B DNA.

24. The cost of sequencing DNA has fallen from about $1 per base pair in the mid-1990s to a tenth of a cent today, and the cost of synthesising the molecule has also fallen.

25. In the next round of replication, the mismatched members of the base pair are separated, and each specifies its normal complementary base. The end result is a transition mutation.

26. We will also stress the importance of hydrogen bonding, base pair geometry, polymerase DNA interactions and the role of accessory proteins in replication fidelity.
