An efficient cDNA amplification procedure is described for determining of the 5' and 3' ends of mRNAs and cloning full-length cDNAs. In this approach, a double-stranded (ds) adaptor is ligated to both ends of a library of ds cDNA by T4 DNA ligase. This adaptor-ligated ds cDNA is then used to selectively amplify 5'- or 3'-cDNA fragments by PCR with a combination of gene-specific and adaptor-spec...
We present a chemical method to selectively tag and enrich thymine modifications, 5-formyluracil (5-fU) and 5-hydroxymethyluracil (5-hmU), found naturally in DNA. Inherent reactivity differences have enabled us to tag 5-fU chemoselectively over its C modification counterpart, 5-formylcytosine (5-fC). We rationalized the enhanced reactivity of 5-fU compared to 5-fC via ab initio quantum mechanic...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
In the fully sequenced Arabidopsis (Arabidopsis thaliana) genome, many gene models are annotated as "hypothetical protein," whose gene structures are predicted solely by computer algorithms with no support from either expressed sequence matches from Arabidopsis, or nucleic acid or protein homologs from other species. In order to confirm their existence and predicted gene structures, a high-thro...
Early in the first year of life infants exhibit equivalent performance distinguishing among people within their own race and within other races. However, with development and experience, their face recognition skills become tuned to groups of people they interact with the most. This developmental tuning is hypothesized to be the origin of adult face processing biases including the other-race bi...
BACKGROUND Riboflavin is known to protect tissue from oxidative damage but, to our knowledge, has not been explored as a means to control exercise-related muscle soreness. This study investigated whether acute ingestion of riboflavin reduces muscle pain and soreness during and after completion of a 161-km ultramarathon and improves functional recovery after the event. METHODS In this double-b...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
