Answer 1

Answer:

The nucleoid (meaning nucleus-like) is an irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material.[1][2][3] The chromosome of a prokaryote is circular, and its length is very large compared to the cell dimensions needing it to be compacted in order to fit. In contrast to the nucleus of a eukaryotic cell, it is not surrounded by a nuclear membrane. Instead, the nucleoid forms by condensation and functional arrangement with the help of chromosomal architectural proteins and RNA molecules as well as DNA supercoiling. The length of a genome widely varies (generally at least a few million base pairs) and a cell may contain multiple copies of it.

Arithmetic mean is termed as sum of n terms/no. of terms n

Here No. of terms is given =n

Mean=x

So sum of n terms =nx

Sum of n-1 terms is= k

Sum of n terms = Sum of n-1 terms +Nth term

nx= k+ Nth term

Nth term = nx-k
