C. radiation that is the answer
It seems that you have missed the given options for this question, but anyway here is the correct answer. The name of the process in which genes are identified by transforming mutant cells and screening for restoration of wild-type function is called CLONING BY COMPLEMENTATION. Hope this answer helps. Thanks for posting.
skin is an animal cell, eukaryotic means there is no cell wall, prokaryotes have cell walls. i hope this helps
The cartoon shows Metaphase I.
Metaphase I has homologous chromosomes that line up at the middle while Metaphase II has single chromosomes that line up at the middle.
A point mutation causes sickle cell anemia. This is a single change in the 6th codon from the start of the HBB gene (codes for the beta-globin subunit).
Normally the 6th codon is for glutamic acid (codon is GAG)...but the point mutation happens at the A .... changing this codon to GUG ...which codes for Valine...
Turns out to be a very seriously bad single point mutation (17 nucleotides from the start of the gene).
