Bacterial genomes:

a. only contain adenine, uracil, cytosine and guanine.

b. when sequenced 100% of the genes are with known cellular function.

c. contain all the information for the structure and functioning of a cell.

d. have rarely been sequenced as it takes a very long time.

c. contain all the information for the structure and functioning of a cell.

Explanation:

Bacterial genome contains all the information for the structure and function of a cell.

An organism's genome represents the total genetic information of an organism. The genome of an organism contains all the necessary information relating to both the structural appearance and function of the organism.

a is incorrect because a genome include DNA of the cell which has thymine instead of uracil. Uracil is only present in RNA.

b is incorrect because sequencing a genes has nothing to do with the function of the gene.

d. is incorrect because bacterial genome consist of few nucleotide sequence and rarely takes time to sequence. Several bacterial genomes have been sequenced in the past.

The correct option is c.

Bacterial genomes: c) contain all the information for the structure and functioning of a cell.

Explanation:

Bacterial genomes are just like in other organisms, they contain all the information for the structure and funcioning of a cell. They are comprised of different chromosomes and/or plasmids and many bacteria are able to do multiple copies of their genome per cell. Bacterial chromosomes must be present for a bacteria to stay alive and reproduce. They have a complex architecture.
