A computer assisted method for the determination of restriction enzyme recognifion sites.
A computer program has been developed which aids in the determination of restriction enzyme recognition sequences. This is achieved by cleaving DNAs of known sequence with a restriction endonuclease and comparing the fragmentation pattern with a computer-generated set of patterns. The feasibility of this approach has been tested using fragmentation patterns of 0X174 DNA produced by enzymes of b...
متن کاملSequence determination of restriction-endonuclease recognition sites.
the enzyme DpnII, produced by another strain of D. pneumoniae, recognizes the same sequence, but is inhibited by this same methylated base. The significance of the occurrence of modified nucleotides in eukaryotic DNA is not as yet understood, although a relationship between modification and gene expression has been proposed by several workers (Waalwijk & Flavell, 1978; Bird et al., 1979). By us...

چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
The average spacing of restriction enzyme recognition sites in DNA.
The discovery of naturally occurring enzymes which cleave DNA at sites specific to particular nucleotide sequences has had a great impact on molecular biology. The function of these enzymes in uivo is to protect bacterial cells from viral invasion by degradation of foreign DNA. Several hundred of these “restriction” enzymes are known and they are a very common tool both for analysis and manipul...
متن کاملA new method for computer-assisted determination of airways resistance.
Conventional methods for determining airways resistance, based on the recording of pressure and flow as X-Y displays, may yield inconsistent results because airways resistance is only one of a number of factors determining the shape of such displays. The temporal behavior of alveolar pressure and flow during panting suggests that the relationship between pressure and flow should be formulated i...
