How many distinct nucleotide sequences of 32 bases exist??

1 answer:

8 0

A sequence of $n$ nucleotides would have $32^n$ possibilities. To exclude repetitions, we count the number of combinations: $\dbinom{32}n=\dfrac{32!}{n!(32-n)!}$

What is the volume of this square pyramid?

tatuchka [14]

Answer: 1296 cm³

Step-by-step explanation:

Since, the volume of a square pyramid is,

$V = \frac{a^2h}{3}$

Where a = side of the square base,

h = height of the pyramid,

By the given diagram,

a = 18 cm,

h = 12 cm,

Hence, the volume of the given pyramid,

$V = \frac{18^2\times 12}{3}$

$= \frac{324\times 12}{3}$

$=\frac{3888}{3}$

$=1296$ cube cm.

⇒ First option is correct.
