PLEASE HELP DNA and RNA are nucleic acids and are composed of nucleotides. The structure of nucleic acids has an effect on the function.

Identify the type of chemical bond and describe the directionality of structure in DNA and RNA. Explain how a change in the subunits can affect their structure and function.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
