1. How many trials did it take for half of the Virtualium atoms to decay?

Biology
1 answer:
Elis [28]3 years ago
6 0

Answer:

Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.

#15. what is the end-replication problem? why, in the absence of telomerase, do the ends of the linear chromosomes get progressi
noname [10]

The DNA replication by the action of DNA polymerase takes place in the 3' to 5' direction on the leading strand. The lagging strand which has the opposite orientation or polarity as that of the leading strand requires a more time to get synthesised. The DNA replication of the lagging strand happens in short segments where a RNA primer forms a compliment with a part of the DNA segment on its 3' end. This RNA primer helps initiate the replication of the Okazaki fragments. When the replication on the lagging strand reaches its end, the RNA primer forms a compliment with the last bit of the strand. This small segment gets missed in the end as no more DNA is left to form a RNA primer-DNA compliment. Such shortening of the lagging strand in the replication process is the end-replication problem.

Telomeres are protective ends of the DNA strands. These ends contain a poly-A tail. When the lagging strand replication reaches its end, the RNA primer forms a compliment with the telomere and initiates the replication. This leads to the shortening of the telomere and not the coding segments on the lagging strand of DNA. The telomerase repairs the shortened telomere by re-synthesising it.

If chemical bonds did not exist, or were so strong that they never broke apart, there would be no movement of ______, which is r
ch4aika [34]

Answer: Energy

Explanation:

If there is no chemical bonds in the substance or the bonds in the substances are so strong so there would be no energy released.

This is because there is a need of energy when any bond is formed and energy is released when bonds are broken down.

Energy is stored in the bonds which is released when bonds are broken down.

There would be no energy available for various processes and no movement of energy will take place.
