Textbook Question
Chapter 15, Problem 11QP
When the human genome sequence was finally completed, scientists were surprised to discover that the genome contains far fewer genes than expected. How many genes are present in the human genome? Scientists have also found that there are many more different kinds of proteins in human cells than there are different genes in the genome. How can this be explained?

- Your advisor, a brilliant bioinformatician, has high regard for your intellect and industry. she suggests that you write a computer program that will identify the exons of protein- coding genes directly from the sequence of the human genome. In preparation for that task, you decide to write down a list of the features that might distinguish protein- coding sequences from intronic DNA and from other sequences in the genome. What features would you list?arrow_forwardYou are interested in finding out the function of a particular gene in the mouse genome. You have determined the nucleotide sequence of the gene, defined the portion that codes for its protein product, and searched the relevant database for similar sequences; however, neither the gene nor the encoded protein resembles anything previously described. What types of additional information about the gene and the encoded protein would you like to know in order to narrow down its function, and why?arrow_forwardDescribe the three basic goals of the Human Genome Project. What are at least three things we have learned from the project? Do you believe it was a worthwhile project? Why or why not?arrow_forward

One of the genes encodes a protein of 600 amino acids and the other gene encodes a protein of 280 amino acids. The mRNA sequences of the two genes do not contain any of the same nucleotide sequences (i.e. they do not overlap). How is this possible?
