Answer:
Prokaryotic cells have entirely different structures for organizing their DNA, the prokaryotic chromosome equivalent is called a genophore and is localized within the nucleoid region... The structure of chromatin networks is currently poorly understood and remains an active area of research in molecular biology.
Explanation:
Answer:
A,C,F,E,D,B
Explanation:
The is the sequence of action potential transmission at at the neuromuscular junction. Generally the arrival of action potential from the presynptic neuron caused influx of ca+ which causes migration and the release of the the acetycholine to the synaptic cleft.
The acetycholine binds with the receptors on the saccolemma to causes opening of Na+ , its influx to causes depolarizarion of the sacolemma. The depolarization of the latter spreads along the transverse tubules, This depolarization causes increases in the permeability of the sacorplasmic reticulum, with opening of ca+ channels and diffusion of Ca+ out of the S. reticulum.
The Ca+ binds to troponin,and tropomyosin exposed the myosin-binding sites on actin filament . The myosin head forms the cross bridges with the filament, and therefore the sacomere shortens leading causing muscle contraction.
Answer:a plasma membrane, DNA,cytoplasm and also ribosomes
