True regarding human genome is/are?

A. Whole genome is involved in transcription

B. There is no gap in coding region

C. 3 x 10⁹ base pairs in 23 chromosomes in each haploid cell

D. Both coding and non-coding regions are equal in amount

E. All the genes are concentrated in coding regions are

Correct Answer » C:E Explanation

Ans. C & E
Whole genome is not involved in transcription.
It includes both protein-coiling DNA genes and noncoding DNA,
Protein-coding gene/regions are distributed unevenly across the chromosomes,
Haploid human genomes (23 chromosomes), which are contained in germ cells (the egg and sperm gamete cells) consist of three billion DNA base pairs.
Non-coding DNA greatly outnumbers coding DNA.
The coding regions of DNA encode all the genes (between 20, 000 and 25,000) of the human organism,where as the noncoding regions of DNA do not encode any genes
