A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.

The bacterial cell grows by the exponential function that is by $2^{number of generation}$ x initial population of bacteria.

In the given question,

Initial population

the initial population of bacteria - 2x 10³ per ml

So per liter, the bacterial population will be 2 x 10 ⁶

Generation time

1 generation time of bacteria is 30 min.

so 5 hours will have-   $\frac{300}{30}$ = 10 generations

New bacterial population

Using formula $2^{number of generation}$ x initial population of bacteria

$2^{10}$ x (2 x 10⁶)

= 1048 x (2 x 10⁶)

2048 x 10⁶

Thus, Option-A is the correct answer.

Why is DNA’s shape considered a “double helix,” but RNA’s structure is not considered a double helix?

bija089 [108]

Because DNA is shaped in the form two helix combined thus creating a double helix. RNA is not shaped this way, instead it is shaped as a sort of twisted half ladder compared to DNA’s twisted full ladder shape
