Answer:
Because DNA molecules are extremely long.
Explanation:
DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.
The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.
Answer:
Oil workers activities involved in the exploration of crude oil and natural gas creates pollution which affects the ecosystem negatively. The various pollutions cause the death of plant and animal life both on land and in water bodies.
The oil workers should be more careful in their activities to prevent oil spillage as much as possible and if there is any at all then there should be adequate measures in the cleaning it up efficiently through biological and harmless chemicals.
