'extensive alternatives' is a correct and usable expression in written English.
It is used to indicate many different choices or possibilities. For example: The new supermarket has an extensive range of alternatives for customers.
The CD44 gene undergoes extensive alternative splicing of its variable exons, leading to the generation of numerous alternatively spliced isoforms.
In addition, we report extensive alternative splicing defects in the brains of BPD subjects compared to controls.
Neurexins are essential presynaptic cell adhesion molecules that are linked to schizophrenia and autism and are subject to extensive alternative splicing.
Automated credit decisions are based on extensive alternative data including a business' shipping and even social history as well as bank records.
The extensive alternative splicing of the pATM gene resembles the complex splicing observed in the hATM and could provide insights for differences observed between mice and humans with regards to the onset of A-T.
Examination of the mouse GRK4 subfamily (GRKs 4, 5, and 6) suggests that mouse GRK4 is not alternatively spliced in a manner analogous to human or rat GRK4, whereas GRK6 undergoes extensive alternative splicing to generate three variants with distinct carboxyl termini.
When compared to the human ATM (hATM), the pATM showed a high level of homology in the coding region, particularly in the regions coding for functional domains, and had extensive alternative splicing of the 5'UTR, characteristic for the human ATM mRNA.
In rNav1.3 or hNav1.3, extensive alternative splicing sites, such as 12v1, 12v2 and 12v3 (rat), as well as 12v1, 12v2, 12v3 and 12v4 (human) in DI-II intracellular loop were identified to be important for channel kinetics (Thimmapaya et al., 2005).
This is in contrast to the extensive alternative splicing that exists in other honeybee neuroligins and NrxI [1].
Secondly, the α/β-hydrolase fold that this domain adopts is notoriously flexible with respect to accommodating extensive alternative splicing, insertions and deletions, and still giving rise to viable protein [56].
