If an embryo had knock-out mutations in both a gap gene and a segment polarity gene, determine which mutant phenotype you would expect to see. Explain your reasoning?

Expert Solution

ANS) The gap genes are expressed early in improvement in huge regions. the products from these genes generally define the unique components of the embryo as a way to later develop into segments. whilst maternal-impact genes have already defined the anterior and posterior end of the embryo, those gap genes outline the region of the pinnacle, thorax and abdominal location.

Those gap genes encode transcription factors that manage the expression of other genes, which includes the pair-rule genes the following institution of segmentation gene. there are numerous exclusive gap genes, every expressed in a particular location. if there is a mutation in certainly one of them in order that it does no longer produce a useful protein, then the segments in that vicinity will no longer nicely develop. this develops a 'hole' inside the body plan of the embryo, and it's how the genes were given their name.

Presume a couple found out their embryo has a gene mutation that has a high success rate of causing cancer later on in the baby’s life. Would you advocate the use of gene therapy in the embryo to correct the problem before the child was ever born? What if the embryo did not appear likely to develop a genetic disease, but the parents decided that they would really prefer that their child have blue eyes as opposed to brown? Would...

Suppose everyone had access to free CRISPR/CAS9 based gene editing to correct mutations at embryonic level. Now answer briefly the following questions 1) Is it true or false that you might not need an artificial repair template to correct the mutation? Explain the reason for your answer (no more than 1 brief sentence). 2) What could still be an ethical concern with gene editing on embryo? Limit your answer to 1 concern.
