Answer:
upper gastrointestinal scan
Explanation:
Upper gastrointestinal series is the radiographic examination of upper gastrointestinal tract. Esophagus, stomach and then duodenum are visible on the X-ray film by the use of the liquid suspension which may be barium or water-soluble contrast.
Fluoroscopy is used during upper GI series. A continuous beam of X-ray rays is passed through body part and is transmitted to the monitor so that body part and the motion of it can be seen in every detail. <u>In upper GI series, the fluoroscopy allows radiologist to see movement of barium through esophagus, stomach, and duodenum as the person drinks.</u>
Answer:
<h2>A</h2>
Explanation:
1. As given, the of a strand DNA contain sequence;
A-T-G-C-C-A-T-C-G-G-T-A,
2. After exposure to UV light, the strand contain the bases;
A-T-G-G*-C-C-A-T-C-G-G-T-A,
3. By comparing both the strands, we find that, the strand of DNA after exposure to UV contain extra G nucleotide between G and C, which is resulted by an insertion.
So we can say that, a new base has been inserted.
