Sentence examples for base at the first from inspiring English sources

A modified base at the first (wobble) position of some tRNA anticodons is critical for deciphering the genetic code.

The presence of a uridine base at the first position of the sequence.

To this kernel, we added information about the presence or the absence of a uridine base at the first position of the sequence.

This finding has the consequence that pyrimidines most likely have a "compensatory" role, which is consistent with DNA structural constraints, and a wobble base at the first anti-codon position.

COLD-PCR DNA sequencing confirmed a proportional increase in the mutant T base at the first position of codon 12 (G12C = GGT→ TGT) as the T c was lowered.

Because of the lack of known conserved characteristics of piRNA sequences (except the occurrence of a uridine base at the first position) and structure (there is no known structure for piRNAs), their identification by computational methods is a difficult task.

from A. pegreffii, an intentional mismatch primer with an artificial mismatched base at the second base from the primer 3′ end was constructed.

(iii) In the third encoding strategy, the signs of x and y are determined by the category of the base at the third codon position, while the absolute values of x and y are decided by the bases at the first and second positions, respectively.

(ii) Following the similar encoding strategy abovementioned, we can also determine the signs of x and y according to the base at the second codon position, and determine the absolute values of x and y by the bases at the first and third positions, respectively.

The target sequence is amplified from a template DNA sample by PCR using two oligonucleotides each containing a single deoxyinosine base at the third position from the 5′ end.

Comparing the codon usage of the predicted ORFs to the anticodons of the resident tRNA complement, one might suggest that 50% of the tRNAs use a wobble base at the third codon position.
