There are an estimated 20,000-25,000 human protein-coding genes. If they are all sorted, which algorithm would you use to find a particular one. Select one: a. Binary Search b. Linear Search c. Ternary Search d. Quick Search

The correct answer is : option A.

Explanation:

Binary search is an array that works by comparing an gene or element in the middle of the array with the desired value, an if the desired value is sorted out and matches with the element , if the element is high than the desired value of the gene the sorting process will continue in the lower half of the array. So, for the finding a particular gene in all sorted protein coding genes the best choice would be binary search algorithm techniques.

Thus, the correct answer is : option A.

sound moves fastest in solids because the molecules are tightly packed and it allows sound to vibrate

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
