Sentence examples for block of sequence from inspiring English sources

A homology search against the PDB database resulted in no significant alignment without extensive gaps for this block of sequence.

Domains of unknown function (DUF) are often annotated in case a clear block of sequence similarity is found within a protein family with unknown function.

Sequence alignments of this region, using the five Mt genomes of Tetrahymena species showed a 94 bp conserved block of sequence in this variable intergenic region (Figure S2).

Interestingly, the more amino terminal SIM1 is in a very highly conserved block of sequence, but this almost completely lacks acidic residues (Figure 1C).

Overall, protein folds and gross functions can be readily transferred from one protein to another by transplanting large blocks of sequence (i.e., domain recombination).

The existence of blocks of sequence conservation may however not be necessary for the conservation of enhancer activity [7].
