Molecular motors interacting with their own tracks.
Dynamics of molecular motors that move along linear lattices and interact with them via reversible destruction of specific lattice bonds is investigated theoretically by analyzing exactly solvable discrete-state "burnt-bridge" models. Molecular motors are viewed as diffusing particles that can asymmetrically break or rebuild periodically distributed weak links when passing over them. Our explic...
متن کاملDynamics of molecular motors with finite processivity on heterogeneous tracks.
The dynamics of molecular motors which occasionally detach from a heterogeneous track like DNA or RNA is considered. Motivated by recent single-molecule experiments, we study a simple model for a motor moving along a disordered track using chemical energy while an external force opposes its motion. The motors also have finite processivity, i.e., they can leave the track with a position-dependen...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولmRNA transport in dendrites: RNA granules, motors, and tracks.
The targeting of mRNAs to neuronal dendrites is an important protein sorting mechanism. Recent studies have revealed that mRNAs are transported by molecular motors. The kinesin superfamily protein KIF5 transports mRNAs such as calcium/calmodulin-dependent kinase IIalpha (CaMKIIalpha) and Arc mRNAs along microtubules in large granules containing proteins involved in RNA transport, protein synthe...
