Textbook Question
Chapter 18, Problem 6TYU
FOCUS ON EVOLUTION
Genes important in the embryonic development of animals, such as homeobox-containing genes, have been relatively well conserved during evolution; that is, they are more similar among different species than are many other genes. Explain why.

Hơ many mismatches would you expect to find between this sequence and the reference sequence?
I know the answer is 3, can you please explain why?
. Let’s say that you have incredible skill and can isolate the white and red patches of tissue from the Drosophila eyes shown in Figure 12-24 in order to isolate mRNA from each tissue preparation. Using your knowledge of DNA techniques from Chapter 10, design an experiment that would allow you to determine whether RNA is transcribed from the white gene in the red tissue or the whitetissue or both. If you need it, you have access to radioactive white-gene DNA
. In examining Figure 3-19, what do you think is the mainreason for the difference in size of yeast and humanmtDNA?

- I need help pleasearrow_forwardMammals are anatomically and physiologically more complex than roundworms, yet both organisms have approximately the same number of genes, about 20,000. Some biologists have argued that mammals and other vertebrates have evolved increased complexity by means of pleiotropy, and that pleiotropy was made possible largely by the evolution of additional enhancers. Propose an explanation for how additional enhancers might produce increased pleiotropy. Can you find examples of this phenomenon?arrow_forwardGive typed full explanation there are about 28,000 copies of zinc finger domains in the human genome, most of them as constituents of transcribed genes. This is a result of what process? Retro transposition of mobile sequences Evolutionary conservation, exon duplication and exon shuffling Evolutionary conversion of leucine zipper, helix-turn-helix, and helix-loop-helix domains into zinc finger domains Evolutionary selection for proteins that interfere with nucleosome packing Genes that “jump” with the help of a transposase.arrow_forward

- Great! Now you have the gene sequence. Now you would like to clone it into an expression vector to grow up in a bacterial system. Because you're going to use bacteria to generate protein from a eukaryote, the mammoth, you need to get rid of introns from your sequence. How do you do that? O Bioinformatically, I look for splice-site sequences and branch-point adenines and predict intron-exon boundaries O l use a comparative genomic approach and use sequence homology with the genome of a closely related species O luse a comparative genomic approach and use sequence homology with the genome of a distantly related species O Both A and B O Both B and Carrow_forwardHuman Biology- MILESTONE 6 X P genetics-and-biotechnology-glo O https://app.sophia.org/spcc/human-biology-2-mile -> Sophia Pathways M Gmail Purdue Global - Sig...
