The genome size of E.coli is approximately 5X106 bp and can be replicated in 30 minutes. The human genome size is 3X109 bp, abou
Oksana_A [137]

Answer:

Human genome has various replicons.

Explanation:

A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .

In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.

if an element has a half-life of 30 million years and there is 12.5% of it remaining in a rock, how old is that rock
Assoli18 [71]

Answer:

The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.

So, after 1 million years you will have 50% of the original substance remaining.

And, after 2 million years you will have 25% of the original substance remaining.

After 3 million years you will have 12.5% of the original substance remaining.

And after 4 million years you will have 6.25% of the original substance remaining.

Explanation:

Hope it helps:)
