D. Mutations involved the genetic variation of the bugs are random
Answer:
Cofilin binds to older actin filaments
Explanation:
Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
Answer:
Eukaryotic translation.
Explanation:
Translation is the process of the formation of the proteins from the RNA molecules with the help of different enzymes and proteins. Translation is quite different in case of prokaryotes and eukaryotes.
The initiation in case of eukaryotes requires different enzymes and translation factors. eIFs are the initiation factors that contains proteins and required for the initiation of eukaryotes translation. eIF1 and eIF1A are the proteins binds with the 40'S ribosome subunit of eukaryotes.
Thus, the correct answer is option (1).
Answer:
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Answer: Motion
Explanation:
Its motion becuase kinetic energy is movement/motion since it moves its balance
