Answer:
Users encounter the error message ‘The Third-party INF doesn’t contain Digital Signature Information’ when they are trying to install third-party drivers on their computer. There are usually two types of drivers present i.e. third-party (these are not developed by manufacturers) and official drivers
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.
The correct option is this: PROTO ONCOGENES BECOMES ONCOGENES.
Proto oncogenes genes are those genes that regulate the process of normal cell division in the living system. These cells starts cell division when necessary and terminate the cell division when the necessary cells have been formed. When these genes lose the power to regulate cell division, the cells continue to divide indefinitely without stopping and this leads to a medical condition called cancer. At this stage, the proto oncogenes have been turned into oncogenes, which are genes that caused uncontrolled cell cycle divisions.
