A piece of DNA fragment is sequenced. You clone the the fragment, isolate the cloned DNA fragment, and set up a series of four dideoxy reaction. You then separate the products of the reaction by gel electrophoresis and obtain the following banding patter: ddATP ddTTP ddCTP ddGTP What is the base sequence of the original fragment that you were given? 0 5-ТАAGCTGA-3' 0 5-АТTCGACТ-3' 5'-TCAGCTTA-3' 5'-AGTCGAAT-3'

Question

Transcribed Image Text:A piece of DNA fragment is sequenced. You clone the fragment, isolate the cloned DNA fragment, and set up a series of four dideoxy reactions. You then separate the products of the reaction by gel electrophoresis and obtain the following banding pattern:
- **ddATP lane:**
- Band 1 (top)
- Band 5 (bottom)
- **ddTTP lane:**
- Band 2
- **ddCTP lane:**
- Band 3
- Band 6 (bottom)
- **ddGTP lane:**
- Band 4
- Band 7 (bottom)
**Question:**
What is the base sequence of the original fragment that you were given?
**Options:**
1. 5'-TAAGCTGA-3'
2. 5'-ATTCGACT-3'
3. 5'-TCAGCTTA-3'
4. 5'-AGTCGAAT-3'
