Codon bias

Noncoding RNA

Number of ORFs

Explanation:
Detailed explanation-1: -Archaea has a unimodal peak at 1.6 Mb, whereas Bacteria show a bimodal peak at ∼1.2 and ∼3.2 Mb. The size distribution of sampled bacterial genomes has a long tail, extending to at least 14.7 Mb[25], although these outliers do not change the overall distribution.
Detailed explanation-2: -An organism’s genome size doesn’t depend on the number of genes (or chromosomes) it contains. In bacteria and viruses, there is a linear relationship between the size of the genome (that is, the totality of DNA) and the number of genes.
Detailed explanation-3: -In prokaryotes (Archaea and Bacteria) there is, in general, a linear relationship between genome size and the number of genes.
