Final answer:

Out of the five sequence reads, two contigs can be made.

Step-by-step explanation:

To determine the number of contigs that can be made out of the given sequence reads, we need to identify any overlapping regions between the reads.

Using the overlap criteria of 3 bases or more, we can find the following overlaps:

  • a. GTCTAGTCGAA
  • b. ACACGCTAGCT
  • c. CGAACGTCGA
  • d. GCTAGCTGATC

From the given sequences, we can see that reads b and c overlap to form the contig ACACGCTAGCTCGAACGTCGA, while reads a and d do not overlap with any other reads. Therefore, we can make 2 contigs out of the given sequence reads.
