(1) The footprints are quite distinct; they must be fresh.

(2) His footprints were clearly evident in the heavy dust.

(3) He squatted down beside the footprints and examined them closely.

(4) One snowy morning footprints and tyre marks were imprinted in the snow.

(5) The intruder had left some clear footprints in the flower beds.

(6) The climber, get past the footprints are unfortunately, lost to forward direction is very dangerous.

(7) In addition to the photos, nothing taken away; In addition to the footprints, nothing left.

(8) The rain had washed away the footprints.

(9) He left a trail of muddy footprints behind him.

(10) I could see footprints in the snow.

(11) He could identify any animal from its footprints.

(12) He left footprints behind him on the sand.

(13) We found footprints pointing towards the back door.

(14) Talk is evanescent, writing leaves footprints.

(15) The snow had obliterated their footprints.

(16) The tide had erased the footprints.

(17) We followed the footprints of a deer in the snow.

(18) I did a little sleuthing to see if I could find any footprints.

(19) They had fled through the snow, and police had followed their footprints.

(20) There were no fresh car tracks or footprints in the snow.

(21) DNase I footprinting assays were performed with 5' end-labelled DNA fragments and bacterial extracts.

(22) The carbon - footprinting process often produces surprises.

(23) CONCLUSION: Phylogenetic footprinting can effectively decrease the false positive rate in predicting transcription factor binding sites.

(24) Ecological footprinting is an accounting tool that represents the environmental impacts of a process or person's lifestyle as an area of land.

(25) The Carbon Trust Footprinting Certification Company has calculated the carbon used in making the bra and will monitor the project to ensure emissions are cut.

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

(27) Scanning: Scanning, or footprinting, is part of the initial information-gathering process for a hacker.

(28) We therefore examined whether these novel bleomycin cleavage sites were also good binding sites by DNase I footprinting.

(29) DNA binding proteins that bind specifically to three probes of positive footprinting area of CEA promoter were detected by electrophoretic mobility shift assay(EMSA).

(30) Ligation mediated PCR is a single-sided PCR technology, its application greatly facilitates the execution of in vivo footprinting study.

(31) Gathering this type of information is part of footprinting, discussed earlier in Categories of attacks, and is used to get extra information on a host.

(32) Recently developed chromatin-immunoprecipitation DNA chip (ChIP-chip) techniques and the phylogenetic footprinting method provide ways to identify TFBSs with high precision.
