Answer:
This composition of nucleotide given in the question do not obey the chargaff"s rule.
Explanation:
According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is
Adenine+Guanine=Thymine+Cytosine
But here the above quation is not maintained because according to the question A+G=49%
and T+C = 51%.

After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
- Algal bloom: the nutrients facilitate the rapid growth of algae
- The bloom of algal species results in the death of underwater plants as a result of inadequate light.
- The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.
- Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia
Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

Most, maybe all, bacteria have their genome DNA tethered to their cell membranes, so it is in the cytoplasm but its not really floating around. Plasmids in bacteria however are free floating. This is why it's so easy to isolate plasmids from bacteria with centrifugation after lysing.
During interphase DNA is copied. So if there was no interphase, the new cells wouldn't have enough DNA.
