Talk:Directionality (molecular biology)

Merge articles?
The article Upstream and downstream (DNA) duplicates information found on this page. It is also short and confusing. Should they be merged? d20 (talk) 16:57, 17 February 2016 (UTC)

Relationship to sense?
Directionality sounds very similar to sense (molecular biology). Please explain the differences in the article. -Pgan002 (talk) 13:53, 24 February 2011 (UTC)
 * There are quite distinct:
 * directionality is a way of saying 'which way you're travelling' along a DNA or RNA strand (e.g. from 5' to 3')
 * sense is a way of describing which DNA strand you're talking about, of the two in a double-stranded DNA (or RNA) helix (e.g. + strand and - strand)

Polyadenylation
It should also be pointed out that the 3' A tailing of active mRNA is only something that Eukaryotes do. Most Bacteria and Archaea can polyadenylate RNA, but they usually do it to flag it for degradation.128.175.254.131 (talk) 05:45, 14 April 2011 (UTC)


 * Why not edit the article to say so? (Preferably adding a suitable reference, which this article needs more of anyway.) Remember the Wikipedia mantra: Be Bold! yoyo (talk) 16:51, 21 June 2012 (UTC)
