Before a cell divides DNA replicates itself. hope this helps!
Answer:
B) Telomerase is a ribonuclear protein containing a section of RNA complementary to the telomeres
C. telomerase is reactivated in cancer cells, contributing to their immortality
Explanation:
- Telomerase elongates telomere ends
- Telomerase binds to a RNA molecule containing a sequence complementary to the telomeric repeat.
- Telomerase is usually not active in somatic cells but is active in cancer cells- the protein acts to extend the shortened telomeres in these cells preventing them from dying
The period of the D string on the violin would be 0.0034 seconds.
<h3>What is the period of a wave?</h3>
The period of a generated wave is the time it takes for the wave's wavelength or successive crests or troughs to pass through a specific point. In other words, it is the time required to complete a full cycle of oscillation.
Mathematically, the period of a wave is given by:
Period = 1/f
where f is the frequency of the wave.
In the case of the D string of the violin in the illustrated problem, the frequency of the wave is given as 293 Hz when it is in tune. Thus, the period can be calculated as:
Period = 1/293
= 0.0034 seconds
Thus, the period of oscillation of wave generated by the D string on the violin with a frequency of 293 Hz is 0.0034 seconds.
