An insertion of a DNA base into a gene can affect an organism by? A changing the sequence of amino acids in a protein
B causing chromosome fragments to form long chains
C causing future gametes to have additional chromosomes
D changing the structure of ribose sugar in nucleic acids​

answer: c.

explanation:

the answer is c.mitochondria. glad to .

the correct answer to this question is #5

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.
