An example of force that acts at distance is gravity and an example of contact force is pushing a chair across the room
Answer:
d. the movement of myosin head while attached to actin myofilament
Explanation:
During muscle contraction, the calcium ions released from the sarcoplasmic reticulum in the sarcoplasm bind to troponin which in turn removes tropomyosin from the myosin-binding sites present on the actin. Hydrolysis of ATP at the myosin heads energize them. These myosin heads with stored energy bind to the myosin-binding sites on the actin filaments. In their bound conditions on the actin filaments, myosin heads are called cross bridges. Only one myosin head of a single myosin molecule forms cross-bridge at a time.
<u>Answer:</u>
Point mutations occur when only one nucleotide is altered affecting only one location or point of the DNA strand.
While Frameshift mutations are caused by the deletion or insertion of a number of nucleotides.
These altered nucleotides affect the triple nature of gene expression disturbing the whole reading frame. All the codons after mutation are different translating a completely different protein. That's why frameshift mutations cause more problems than point mutations.
