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

- Human Genome ProjectIn 2003, the Human Genome Project was successfully completed, determining the exact sequence of the entire human genome, which is made up of 3 billion nucleotide base pairs. The data generated from the Human Genome Project is freely available online to anyone. Many pieces of research and innovations stemmed from the HGP, allowing the identifications of 1 800 disease genes. Many of the corporations using the results from the HGP are privately funded, and research is being done for profit even though the HGP results are provided freely.

- Concept 23. A gene is a discrete sequence of DNA nucleotides. This concept describes the discovery of the DNA sequencing technique that made modern biology and bioinformatics possible. The method was later used to sequence the human genome and genomes of many other organisms. This led to the accumulation of great numbers of nucleotide and protein sequences in the numerous databases. The concept 23 web page is here: http://www.dnaftb.org/23/ After reading the Concept page, answer the following questions. What was the Mendel’s definition of a gene? How was it different from the definition by Beadle and Tatum? Describe proteins based on the early sequencing efforts. What was the definition of a protein coding gene based on the genetic code? What are the beginning and ending codons of the gene’s protein coding sequence? What is the name of the method that makes use of a “defective” DNA nucleotide? After reviewing the Animation pages, answer the following…arrow_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
- When comparing evolutionary similarities between different genes within a gene family, it is usually more straightforward to compare genes by using the protein sequences of gene products rather than DNA sequences of the genes themselves. Explain why this is the case.

- hello i need help with this DNA sometimes has chemicalgroups attached, called methyl groups, that affect geneexpression. Suppose that, during each hour, first a fractionm of unmethylated locations on the DNA become methylated,and then a fraction u of methylated locations become unmethylated. Find a recursion for the fraction f of theDNA molecule that is methylated.arrow_forwardRead This! Extensive research has been done to find similarities and differences in the DNA sequences of different an- imals. This work is very difficult and time consuming, but it can help biologists determine the evolution- ary ancestry of a species. For example, when investigating the human genome, biologists found that about 99.5% of the DNA sequences among humans are the same. Considering the wide variety of traits in the human population, we are a lot more similar than we are different. Humans share approximately 96% of their DNA sequences with chimpanzees, 85% with mice, and 75% with chickens. 16. Study the table below.

A person with two mutated alleles for this gene makes more of the reddish melanin than the brownish melanin, resulting in red hair and pa le skin. DNA extracted from two Neanderthal fossils contains a mutated MC1R allele that has not yet been found in humans, To see how the. Neanderthal mutation affects the function of the MC1R gene, Carles Lalueza-Fox and her team introduced the allele into cultured monkey cells (FIGURE 26.1 6). FIGURE 26.16 MC1R activity in monkey cells transgenic for an unmutated MClR gene, the Neanderthal MC1R allele or the gene for green fluorescent protein (GFP). GFP is- not related to MC1R. 2.
