One potential mechanism for generating this variation is the rearrangement of the mt genome to move coding regions to a position proximate to a different promoter, resulting in novel mRNA types.
This procedure ensures every estimate of ARGOS error was based on a GPS position proximate in both space and time to the true position of the animal.
8 Moreover, the 23S rRNA is tolerant to circular permutation, 9 indicating that it might be possible to circularly permute the 23S rRNA to open up new 5′ and 3′ termini at positions proximate to surface exposed features of the 16S rRNA, and then insert this permuted 23S at that site on the 16S, connected on both ends by an RNA linker.
However, both sites are positioned proximate to the 3′ and 5′ termini of the 3′UTR (Fig. 7a).
How it works at a proximate level, though, is a little more challenging for students to grasp.
This differential age effect is most likely explained by male factors, at least at a proximate level.
At a proximate level, this low survival rate must contribute to the precarious conservation status of the Blue Mountains Water Skink.
At a proximate level, temperature affects the cellular and biochemical rates of differentiation and growth during development [ 33- 35].
The implantation on the maxillary molar area is in a proximate position with the maxillary sinus, so there is a risk of perforation during the implantation of the dental implant fixture, and the maxilla proximate maxillary sinus usually has insufficient bone width for implantation.
Fannie and Freddie, they say (implausibly) in a recent position paper, "were the proximate cause of the financial crisis" and "at the forefront of a relentless push to drive down lending standards," etc. etc.
Always stay at a tight streamline position.
