The correct answer is C. troponin only.
The smooth muscle cells contain similar elements like the cardiac and skeletal muscle cells including actin, myosin and tropomyosin but they contain troponin.
Smooth muscle tissues are non striated and produce their own connective tissue called endomysium. Smooth muscle cells also lack sarcomeres but have other thin and thick filaments along with actin and myosin contractile proteins.
Due to lack of troponin the cross bridge formation is regulated by the regulatory protein calmodulin instead of the troponin- tropomyosin complex.
Spontaneous Malformation Is the answer
Ergocalciferol is the form of vitamin d found in plants.
dsDNA, upon entry to the <u>cell</u>, can be immediately copied into mRNA.
dsDNA- Two polynucleotide chains with nitrogenous bases joined by hydrogen bonds make up double-stranded DNA. Due to the anti orientation of the sugar-phosphate backbones and the complimentary nature of the A-T and C-G base pairing, one strand in this arrangement mimics the other.
Cell- The science of structure and function of cells is known as cell biology, and it is based on the idea that a cell is the basic building block of all life. A thorough understanding of the organisms and tissues that cells make up is made possible by concentrating on the cell.
