61) White, who is doing research on the disease, was able to determine its DNA sequence.

62) Other methods of genetic purification can homogenize a DNA sequence.

63) There were no detectable p53 mutations in genomic DNA from the six children who developed secondary brain tumours.

64) Experts are still analyzing the DNA evidence in the case.

65) These four bases provide the only source of variation in the DNA molecule.

66) It can be estimated that at least twelve DNA fragments are detected by the probe.

67) It replicates itself, making two DNA molecules where before there was one; and it makes protein.

68) The predicted 5' and 3' boundaries of the expression regions were confirmed by direct plasmid DNA sequencing.

69) A thermostable DNA polymerase is added to the same tube.

70) In fact[sentencedict.com], only about five per cent of each DNA molecule actually provides any meaningful code.

71) Immunocytochemistry can then be used as a marker of p53 mutation, although DNA sequencing remains the gold standard.

72) It is the gradual reorganisation of the genetic program, the software coded into DNA sequences.

73) A DNA sample taken from the exhumed body of the A6 murderer James Hanratty has reportedly confirmed his guilt.

74) Dusky seaside DNA is, as far as can be seen, identical to that of other, commonplace, sparrows nearby.

75) Occasionally, the DNA copying process involved in reproduction may go wrong.

76) Voice over Police are now using DNA testing, or genetic fingerprinting in an attempt to track down the rapist.

77) However, Mr Klevan said that subsequent DNA analysis had established that the baby was Gilfoyle's.

78) This method provides a means of obtaining DNA markers distributed along the length of a specific restriction fragment.

79) The more drugs that one gives, the more likely it is that damage to host DNA polymerase will take place.

80) Police are almost certain the torso was Mr Davison but they're awaiting confirmation by a DNA test.

81) Direct DNA sequencing of the relevant amplification products in both patients was used to characterize each mutation.

82) But also, some time around the middle of interphase, the DNA replicates itself.

83) It therefore seems that both DNA structure and hydrogen bonding to guanine contribute towards sequence recognition.

84) Just one base wrong in a particular DNA sequence may cause a coding error in the protein formed by that gene.

85) The whole process is emphatically led by the cytoplasm-which continues to divide whether DNA replication is completed or not.

86) So acyclovir phosphate and triphosphate are not formed in healthy cells, whose DNA synthesis is therefore not affected.

87) The only thing missing was DNA evidence and the Bruno Magli loafers.

88) Specimens are now providing DNA samples that could answer questions about evolutionary links.

89) The messages that DNA molecules contain are all but eternal when seen against the time scale of individual lifetimes.

90) In three patients, no analysable DNA histogram could be generated because their tumours had been fixed in Bouin's solution.
