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?
Approximately what portion of the human genome is composed of repeat sequences?
Please use information from the text below and your knowledge of biology to answer the final two (2) questions.
In 2003, as a result of the Human Genome Project, the complete sequence of all the bases in human DNA was released to the public. Although knowing the entire sequence of bases has proven valuable, scientists are currently working to map genes. Mapping genes involves determining the exact location of each gene. Since much of human DNA does not code for a protein, it is challenging to figure out which segments are actual genes. Often, scientists look at the percent composition of bases in a segment of DNA. If the segment of DNA has a large percentage of C and G bases (together over 50%), it is likely that it is a gene and codes for a protein.
10. Is it likely this segment of DNA codes for a protein? State 'yes' or 'no' AND support your answer using information from the text.

A scientist analyzed the bases in a segment of DNA from a human skin cell to determine if it codes for a protein. The base A (Adenine) is 11% of the bases in this segment of DNA. Calculate the percentage of bases that would be C…arrow_forward(a) Why can there be multiple codons for an amino acid? Why would this have evolved? (b) What is the advantage of Illumina Next Generation Sequencing?arrow_forwardA researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely? A. All of the bacterial DNA consists of coding sequences, but this is not true of the eukaryotic DNA. B. There are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. C. There are densely packed genes in the eukaryotic DNA that were not immediately distinguishable during the first analysis. D. The bacteria have larger quantities of noncoding DNA than the eukaryotic cells.arrow_forward
