Colt1911 [192]3 years ago
3 0

Answer:

The correct answer will be option D (they are complementary).

Explanation:

Complementary DNA or cDNA is an edited DNA molecule synthesized from a single-stranded RNA called mRNA. The reaction of cDNA formation from mRNA is catalyzed by an enzyme called "reverse transcriptase".

The cDNA strands formed is also known as a complementary copy of mRNA as it contains no introns or non-coding sequence in its sequence similar to mRNA. cDNA is used in recombinant DNA technology to clone eukaryotic genes in prokaryotes.

Thus, option D (they are complementary) is the correct answer.

What part of the intestinal tract prevents backflow of food from the stomach into the esophagus? a. diaphragm b. lower esophagea
lara31 [8.8K]

Answer:

The correct option is b. lower esophageal sphincter

Explanation:

The esophagus is the initial part of the digestive tract and its function is the transport of the alimentary bolus from the pharynx to the stomach, through the thorax and avoid the reflux thereof. It begins and ends in two sphincter structures, the upper esophageal sphincter and the lower esophageal sphincter, which separate it from the pharynx and stomach. The lower esophageal sphincter has two functions: relax during swallowing and prevent reflux of the gastric contents into the esophagus in the postdeglutory period. After swallowing, there is a relaxation of the lower esophageal sphincter, pressure dropping to levels similar to those of the gastric fundus, which allows the bolus to enter the stomach. This relaxation lasts a few seconds and is followed by a strong contraction that prevents backflow of food.
