Sentence examples for base pair at the from inspiring English sources

The different WP2 strains all carry the same AT base pair at the critical mutation site within the trpE gene.

In general the WP2 strains are used as a substitute for, or as an addition to Salmonella strain TA102 which also carries an AT base pair at the mutation site.

To assess the influence of a single nucleotide substitution on the SERS signals, we repeated the calculations replacing a single CG base pair at the beginning of the block with an AT base pair.

The data reveal that the common element among the three most stimulatory codons is the potential to form a stable GC base pair at the second position.

The lower abundance of this tRNA in combination with the less stable G36U1 base pair at the first position of this pair may account for the lower frequency of misreading of this codon as compared to AGC Ser.

This potential to form base pairing interactions at all three positions, which is possibly nucleated by a strong Watson-Crick base pair at the second position would allow transient formation of the mRNA:tRNA mini-helix.

Strains TA102 and TA104 contain AT base pairs at the hisG428 mutant site.

This led us to further investigate two questions: (1) How important are more RNA pairings that extend beyond this central core of 10 base pairs at the helical terminus?

On the contrary, the second class of target sites has imperfect complementary base pairing at the 5′-end of the miRNAs, but it is compensated via additional base pairings in the 3′-end of the miRNAs.

ZFNs can induce DNA double-strand breaks at specific genomic locations and drive the introduction of an insertion or deletion of base pairs at the targeted region, consequently resulting in a loss-of-function mutation.

Instead, tRNATyr(GΨA) alone appears to act as a tRNA decoder of TMV-UAG and TMV-UAA via non-canonical base pairing at the first anticodon position [29].
