Answer:
- Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
- <em>Oviductus oblatus</em> are indeed eukaryotic cells
Explanation:
In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a <u>polymer of proteinic subunits</u> united by weak, not covalent connections.
The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.
Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.
Actin filaments have directionality which means that their extremes have different structures.
In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why <u>they are often used as molecular markers</u> for different studies.
Answer:
Explanation:
Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species
Botulinum toxin commonly acts by binding to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. Through this mechanism, muscle movement is inhibited in the area it is injected to.
