Question
Please help me verify my answers
The human eye contains cells in the retina, which express light-sensing proteins called opsins, which convert light energy into electrical signals during vision. Do cells in your big toe carry opsin genes? If so, are those genes expressed? Two sisters are born several years apart to the same parents. What proportion of genetic material is shared between the two of them? What is the probability that two children, resulting from separate fertilization events from the same parents, share all their genetic material? (Ignore the effect of crossing over.) Describe what a 'somatic nuclear transfer' experiment is. How is cloning different from in vitro fertilization, in which a sperm and egg are combined in the test tube? Suppose it is the year 2040. You have a close friend who is in need of a new kidney. They are offered two choices: (j) a kidney transplant from a donor. (ii) cells from their body could be used to generate a synthetic (cloned) embryo, from which stem cells could be obtained to repair their own kidney. (iii) Their own body cells could be reprogrammed to make induced pluripotent stem (iPS) cells, from which kidney cells could be made. Which do you recommend your friend choose, and why? (There is no right answer; this is a hypothetical situation for you to consider how availability of new technologies might directly impact human health.)Explanation / Answer
Answer:
2. The theory of genomic equivalence states that all cells of an organism contain an equivalent complement of genetic information. So, cells of the big toe also carries genes for opsin.
The specific components of a given cell provides its special characteristics. These components are either synthesized by proteins, or are themselves proteins. By expressing different subsets of genes, two cells contain different subsets of gene products (proteins). So, although the cells of the big toe contains the genes for opsin, they are not expressed.
