Sentence examples for molecules that lack from inspiring English sources

Inorganic polymer, any of a class of large molecules that lack carbon and are polymers that is, made up of many small repeating units called monomers.

The unique structure of dHV genomes consisting of linear DNA molecules that lack AAV ITRs at one or both ends in their monomeric and dimeric configuration, respectively, precludes the generation of circular integration substrates via AAV ITR-mediated recombination.

Surface Kb molecules that lack exon 7, by contrast, appear to traffic readily into early endosomal compartments, but are significantly delayed in their ability to traffic into late endosomes or lysosomes.

Additionally, class II MHC molecules that lack the cytoplasmic lysine of the β-chain display a decreased localization to the internal vesicles of multivesicular bodies, suggesting that ubiquitination is important as a signal for the inclusion of class II MHC in these internal vesicles [5], [6].

The addition of this second frequency dimension allows for separation of lac from lipids and macromolecules, molecules that lack J-coupling properties.

The apparent reduced affinity is mostly due to the fact that scFv are monovalent molecules that lack the avidity binding obtained through dimerization.

On the other hand, APE1 inhibitor molecules that lacked obvious DNA-binding features (i.e. fused aromatic ring structures or positively charged groups), such as thiolactomycin and Tyrphostin AG 538, yielded weak or no displacement activity.

These increases were understandably less dramatic than those observed in vitro in which the events were synchronized by cross-linking cell surface mutant CEA molecules that lacked self-adhesive external domains [21].

For example, the combination of a forward primer from the end of segment 3 (before the first IES) with a reverse primer from inverted segments −2 and/or −1 avoided macronuclear DNA contamination and permitted dense sampling of partially-processed molecules that lacked inversions.

As an example, in an initiator transfer RNA (tRNA) molecule that lacks a methyl group (tRNAiMet), modification at position 58 of the tRNA chain renders the molecule unstable and hence nonfunctional; the nonfunctional chain is destroyed by cellular tRNA quality control mechanisms.

In Hela cells stably expressing these molecules, chimeras with a Tyr-723 were rapidly endocytosed, while chimeras containing other amino acids at position 723, including a Phe, were internalized at rates only slightly faster than a CD4 molecule that lacked a cytoplasmic domain.
