- Genetically Modified Foods The creation of transgenic crop plants using recombinant DNA methods involves the transfer of just one gene or a small number of genes to the plants, in contrast to classical breeding methods in which hundreds or even thousands of genes are transferred at once. Explain why this is true. If fewer genes are transferred during the creation of transgenic crops, why are some people afraid that they are dangerous?arrow_forward*00 g organisms use nformation from e is nearly identical ants, and animals. These two enzymes are found in nearly all living organisms. When you studied the cytoskeleton, you learned about the proteins actin and tubulin. Actin and tubulin are found in all eukaryotes.

- Mutations occur randomly during the process of gene expression or by exposure to mutagens. While some mutations are detrimental, others can create proteins that have positive capabilities. In order for a mutation to be passed to future generations, what must be true about the mutation? * O It must occur during the first stage of DNA replication. O It must result in a longer polypeptide chain than normal. O It must be exposed to extensive radiation. O It must occur in cells that give rise to gametes.arrow_forward1 Please answer this asaparrow_forwardpls help me to do these my activity and answer properlyarrow_forward
- Random mutations only very rarely result in changes in a protein that improve its usefulness for the cell, yet useful mutations are selected in evolution. Because these changes are so rare, for each useful mutation there are innumerable mutations that lead to either no improvement or inactive proteins. Why, then, do cells not contain millions of proteins that are of no use?arrow_forward11arrow_forwardHelparrow_forward
