The answer is D. They carry out specific functions for a whole organism
Answer:
Explanation:
When viruses cause an infection, they spread their DNA, affecting heathy cells' genetic makeup and potentially causing them to turn into cancer. HPV infections, for instance, cause the virus' DNA to combine with the host's DNA, disrupting the normal function of cells.
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
Introns because they are coding sequences.
Exons because they are non-coding sequences.
Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
