Why are telomeres problematic for eukaryotic chromosome replication? a) They are highly repetitive and thus hard to replicate co
Natalka [10]

Answer: Option E

Maintaining very long telomeres promotes cancer cell formation.

Explanation:

Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.

Usually, in eukaryote chromosome replication, telomeres are not replicated.

Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.

The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres

How does a lyric virus kill the cells that it infects
Aleksandr [31]

The half life of Carbon 14 is 5500 years. How many years will pass for a 30 gram sample to reach 3.75 grams
sertanlavr [38]
Half life is the time taken by a radioactive isotope to decay by half of its original mass. In this case the half life of carbon-14 is 5500 years. 
The original mass is 30 g and the new mass is 3.75 g. 
New mass = Original mass × (1/2)^n, where n is the number of half lives; 
3.75 = 30 × (1/2)^n
 1/8 = (1/2)^n
 n = 3 
Thus, the time taken will be; 3 × 5500 = 16500 years.
