Final answer:
The altele(s) in this stretch of DNA are CAGT and CAGTCAGTCAGTCAGTCAGT.
Step-by-step explanation:
To identify the altele(s) in the given stretch of DNA, we need to compare the top and bottom fragments. The altele(s) are the sequences that are different between the two fragments.
The top fragment is GCAATCAGTCAGTCAGTTATCGGG, and the bottom fragment is GCAATCAGTCAGTCAGTCAGTCAGTTATCGGG.
The altele(s) in this stretch of DNA are: a. CAGT and e. CAGTCAGTCAGTCAGTCAGT. These sequences are present in the bottom fragment but not in the top fragment.
