In the box, use the format >mysequence for the name of sequence (FASTA format) and then on the next line , paste in your sequence. The ORF Finder program at the NCBI site is also a very handy program, but it needs a longer sequence and searches for the presence of an ATG (so not appropriate for this question). QUESTION 2 How many genes (approximately) would you expect a human DNA sequence of 400 kb to contain? If it were bacterial DNA (instead of human), how many genes would you expect to see and why? QUESTION 3 Suppose you have analyzed a section of the bacterial X genome and find a bidirectional promoter within the position of the box. (The region within the box contains 150 bp which are not shown). within the position of the box....
