In E. coli, there is a mutation in a gene called dnaB that alters the helicase that normally acts at the origin of replication.
kvasek [131]

Answer:

When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.

Nadusha1986 [10]

Answer:

The organism to have maximum energy would be the algae since ii will be at the lowest level. so the answer is 'B'.

The pyramid of energy shows the flow of energy from one trophic level to other. The lowest trophic level is occupied by the producers. In this case algae acts as the producer. Krill acts as the primary consumer, followed by leopard seal as the secondary consumer and finally killer whale as the tertiary consumer. The <em>lowest trophic level </em> contains maximum energy.

STALIN [3.7K]

Answer:

multicellular.

Explanation:

Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.
