WP is a survey of knowledge at the encylopedic level--it does not include each scientific report separately, but at the summary level that would correspond ,ore closely to a published review article. If a journal publishes an article on something, of particular interest, almost always other journal articles will deal with the subject also--and the Wikipedia article on the subject should be written to present an account of all of them together--with the paper in RNA or other particular paper only one of several references.
To the extent that the journal publishes papers that are sufficiently broad to meet the description of a summary at the integrative level of an encyclopedia (and the first one mentioned does seem to be of this sort), then they are suitable for WP. I would be surprised if all or even the majority of the papers in any particular scientific journal were of this nature. It's not just quality, or appropriate level of writing, its sufficient generality.
But that's the great thing about a wiki - we can come along afterwards and merge articles and otherwise fiddle around with them to get them to meet our requirements. We don't need to turn down contributions just because they're not perfect.
