Mitochondria are thought to be the descendants of certain alpha-proteobacteria. They are, however, no longer able to lead indepe
ndent lives because most genes originally present on their chromosome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes? a. plasmolysis
b. conjugation
c. translation
d. endocytosis
e. horizontal gene transfer
Horizontal gene transfer(HGT) is mainly seen in bacteria. Bacteria exchange their genetic material from the horizontal gene transfer method. There are three methods in HGT- conjugation, transduction, and transformation.
In conjugation, the bacteria exchange their plasmid through sex pilus. In transformation, bacteria take up other's genetic material from its environment and in transduction virus-mediated gene transfer occurs.
Therefore in bacteria and nucleus, the genetic material exchange can occur only through HGT.
1. We can lessen our impact on Earth by using more renewable resources instead of nonrenewable resources. If we were to use these we would stop wasting so much unneeded energy.
Explanation: carbon can have a lot of effect on life, we like cutting down tress, it have a lot of effect on our ecosystem because we are slowly destroying carbon dioxide to be no more.
