The major determinant for the identity of alanine tRNAs is a single base pair in the acceptor helix that is proximal to the site of amino acid attachment. A 7-base-pair microhelix that recreates the acceptor helix can be charged with alanine. No other examples of charging of small helices with specific amino acids have been reported, to our knowledge. We show here that a 13-base-pair and an 8-b...

The nucleotide sequence of a 1.46 kb cDNA, selected from a human liver library by the expression of fumarase antigenic determinants, was determined using the dideoxy chain termination method. The cDNA contained an open reading frame extending from the extreme 5'-base and coding for a protein with 468 amino acids. This protein, with the exception of an N-terminal methionine, was identified as mi...

The Palmprint verification is a process of verifying the identity of the applicants. It performs one to one comparison between a newly input Palm print and the Palm print for the claimed identity that is stored in the database. In this paper, convolution filter and feature extraction using NI Vision Assistant 2009 has been used for detection. The feature extraction is templates of different siz...

We present TFAM, an automated, statistical method to classify the identity of tRNAs. TFAM, currently optimized for bacteria, classifies initiator tRNAs and predicts the charging identity of both typical and atypical tRNAs such as suppressors with high confidence. We show statistical evidence for extensive variation in tRNA identity determinants among bacterial genomes due to variation in overal...

The present study aims to study the sociological factors affecting the lifestyle of the youth. This research is a survey research in terms of control of the research conditions, and because it's done at a given time is a cross-sectional study. The statistical population of the study consisted of all young boys between 15 to 29 in Khalkhal who were 7149 persons according to the population and Ho...

Orthopteroid insects (cockroaches, crickets, locusts and related species) allow examination of active sensory processing in a comparative framework. Some orthopteroids possess long, mobile antennae endowed with many chemo- and mechanoreceptors. When the antennae are touched, an animal's response depends upon the identity of the stimulus. For example, contact with a predator may lead to escape, ...

The repair of oxidative base lesions in DNA is a coordinated chain of reactions that includes removal of the damaged base, incision of the phosphodiester backbone at the abasic sugar residue, incorporation of an undamaged nucleotide and sealing of the DNA strand break. Although removal of a damaged base in mammalian cells is initiated primarily by a damage-specific DNA glycosylase, several lyas...

We build an endofunctor in the category of small categories along with the necessary structure on it to turn it into a path object suitable for homotopy theory and modelling identity types in Martin-Löf type theory. We construct the free Grothendieck bifibration over a base category generated by an arbitrary functor to that category.
