molecules.

Imagine you took a protein coding sequence of DNA (a gene) from a pig, and added that sequence of DNA to a fruit fly. What would the resulting protein be like?
The gene could be expressed, but it would be the fly version of the same gene
The protein would be identical to the pig version of the protein
The protein would be a mutated version of the pig protein
No protein could be produced because of the difference in species

- What effects do mutations have on organisms? O All mutations are harmful because they disrupt protein function or gene regulation % All mutations are beneficial to organisms because they improve protein function or gene regulation All mutations have no effect on organisms, because they do not significantly affect protein function or gene regulation Some mutations are harmful, some are beneficial, and some have no effect on the organismarrow_forwardMutations in DNA may or may not result in a change in the phenotype of an organism. In which of the following situations will a mutation appear in the phenotype of an individual? The mutation occurs in an organism which is past reproductive age The genetic code for protein synthesis has not been altered in a gamete producing cell The mutation occurs in a body cell of the organism, resulting in cancer O The mutation results in a change in the amino acid sequence of the protein in a gamete producing cellarrow_forwardSuppose that a rare DNA replication error results in the duplication of a single gene, giving the daughter cell two copies of the same gene. How does this change favor the acquisition of a new function by the daughter cell? The copy can undergo a gain-of-function or loss-of-function mutation without altering the original gene's function. The copy has already-formed domains with biological activity, so new functions do not need to evolve de novo. The duplicated gene increases the rate at which the cell can perform the function encoded by the original gene. The two genes can combine to form a new gene that encodes a protein with a new, additional function. The cell can make additional proteins, which then undergo alterations and can give rise to new functions.arrow_forward
- Some mutations or changes in the sequence of DNA, do not have any offect on the characteristics of the organism. Why Is this? The protein from this mutated sequence deactivated by the cell The mutated sequence still codes for the same amino acid The cell recognizes mutations and ignores them when expressing the gene The immune system repairs the mutated sequence during developmentarrow_forwardIn 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a persons own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwangs group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?arrow_forwardA controversial issue, closely related to cloning, that has caused a lot of debate is the use of embryonic stem cells. One possible application of these cells is that they may be able to supply replacement tissues to treat diseases such as Parkinson's disease, diabetes, paralysis due to spinal cord injuries, and other degenerative diseases. The word "embryonic", has caused fierce opposition to this type of research because embryos are destroyed when the stem cells are removed. Questions that have surfaced in this debate include: When a cell nucleus is transferred to another cell, have we created life? Does a stem cell have the same status as a human? What should be done with the embryos that are leftover at in vitro fertilization (IVF), clinics? Advocates argue that the medical benefits of stem cell research would be enormous. Opponents argue that life begins at conception and thus this type of research is abortion. Based on what you have read, explain why you are for or against stem…arrow_forward
