The answer is Retroviruses integrate DNA randomly in the
genome. While retroviruses integrate their
DNA permanently in their host genome, hence
a good tool for gene therapy, its risk of inserting
DNA at an unintended
location on target genome can cause insertional
mutagenesis. This mutation can cause activation of oncogenes hence lead to tumor
growth.
The three parts are the endosperm, embryo, and the seed coat.
I hope that answered your question.
Explanation:
The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. ... At night, Earth's surface cools, releasing heat back into the air.
