The phrase "because alternatively" is correct and can be used in written English.
It is typically used as a transitional phrase to introduce a contrasting or alternative explanation for something. Example: We decided to cancel the outdoor event due to the rainy weather. Because alternatively, we could hold it indoors at the community center.
We are certain that alternative splicing does not occur that close to the stop codon, because alternatively spliced transcripts would be included in the Ensembl database and as such would have been subject of our genome-wide in silico screen.
Parsimoniously, this suggests that the few archaeal polymorphic toxin systems were acquired from bacterial versions, because alternatively it would require a large number of gene losses in different archaeal linaeges.
The lack of significant structural perturbations occurred because alternatively spliced segments were either short regions on the surface of the structure (for two pairs) or were disordered regions (for the remaining three pairs).
Alternatively, because, for lower signal intensities, higher accuracy is desirable, a nonlinear function (e.g., square root transform as illustrated in Fig. 10) is applied by some imaging devices.
High firing rates may occur because of strong sensory drive or, alternatively, because presynaptic neurons are highly excitable.
This may be because of low statistical power or, alternatively, because other factors are more important for the prediction of tamoxifen therapy.
Design generally begins either because of a need or requirement or, alternatively, because of an idea.
This result can occur either because both diseases increase and TB does so at a faster rate, or because TB increases and HIV decreases, or alternatively because both diseases decrease but TB does so at a slower rate than HIV.
Sotomayor and her colleagues assert that they issued the summary order because of the thoroughness of the district-court opinion, or, alternatively, because of overwork.
Indeed, early maturing girls are hypothesized to have the most adjustment difficulties because they are physically most deviant from their peers or alternatively, because they have the shortest period of time to adjust to new social and behavioral norms (Negriff and Susman 2011).
