What does myosin attach to?
During muscle contraction, myosin cross bridges attach to active sites of ACTIN FILAMENTS.
During skeletal muscle contraction myosin cross bridges attach to active sites of?
During skeletal muscle contraction myosin cross bridges attach to active sites of actin filaments. Actin filaments bind ATP. Their growth is regulated by thymosin and profilin.
During muscle contraction myosin cross bridges attach to which active sites?
actin filaments
Myosin cross bridges attach to active sites of?
actin filaments in muscle cells during muscle contraction.
During mitosis microtubles attach to chromosomes at the?
kinetochores, which are protein structures found at the centromere of each chromosome. The microtubules attach to the kinetochores and help to accurately separate the duplicated chromosomes into two daughter cells during cell division.
When do spindle fibers attach to chromosomes?
Spindle fibers attach to chromosomes during metaphase of mitosis. Special protein structures called kinetochores on the chromosomes interact with the spindle fibers to ensure proper alignment and segregation of the chromosomes during cell division.
How do spindle fibers attach to chromosomes and line them up during cell division?
Spindle fibers attach to chromosomes by binding to specific protein structures called kinetochores located on the centromere of each chromosome. The spindle fibers then exert tension on the chromosomes, aligning them along the cell's equator during cell division.
What structures pull the chromosomes apart?
The spindle fibers, which are composed of microtubules, pull the chromosomes apart during cell division. These fibers attach to the centromeres of the chromosomes and help guide them to opposite poles of the cell during mitosis or meiosis.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
How many hills and bridges does the brook pass during his journey?
The brook passes over one hill and under three bridges during his journey.
What is steel erection?
Steel erection means the construction, alteration or repair of steel buildings, bridges and other structures, including the installation of metal decking and all planking used during the process of erection
A short thick appendage that enables bacterium escherichia coil to attach to other surfaces is called?
The short thick appendage in Escherichia coli that allows it to attach to surfaces is called a pilus or fimbriae. These structures aid in adherence to host cells or environmental surfaces during infection.
