The phrase "a element" is not correct in written English.
The correct form is "an element" due to the vowel sound that follows the article.
Example: "An element of surprise can enhance the effectiveness of a presentation."
Alternatives: "one element" or "a component".
As a result, hydrogen interacts more strongly with the B element than the A element in every hydrogen storage alloy, despite the fact that the A element has a larger affinity for hydrogen than the B element in the binary metal hydrogen system.
This was termed the A element.
Separation of the A and B elements by insertion of a 256 spacer showed activity similar to wildtype, and individual mutations of the A element in the MA construct and in the MAB construct showed diminished activity (Figure 7B).
The yellow-h gene likely moved from the F element to the A element in D. mojavensis.
Instead, the X chromosome consists of the F element and the A element separated by the nucleolus organizer (NO).
In contrast, both the PRY and Or13a genes likely moved from other chromosomes (the Y chromosome and the A element, respectively) to the D. mojavensis F element.
Five primers were designed from the orf region of the HeT-A element (Supporting Information, Table S1).
Transcription begins at the 3'UTR end of the immediately upstream HeT-A element and extents along the complete downstream copy [ 28].
The enhancer-A element of the MHC class I promoter encompasses two NFKB binding sites and plays an important role in the constitutive and cytokine-induced expression of MHC class I genes.
Previous studies have attempted to classify the genomic copies of the HeT-A element in several subfamilies according to their variability in the 3'UTR [ 6] and also in the ORF [ 7].
For example, in the CoDi-A case an intermediate node represents any putative sequence halfway between the conventional Ty1/Copia and their CoDi-A counterparts (for instance a CoDi-A element without chromodomain), etc.
