Answer:
The gastrointestinal tract comprises of Mouth-Esophagus-Stomach-Small intestine-Colon-Rectum.
Liver, pancreas and gallbladder are solid organs of digestive system.
Explanation:
Digestion is the process involved in the conversion of large complex food molecules into smaller nutrients that can be used by body cells for survival and carry out their function. The digestive system comprises of various subsequent organs that digest the food.
- Digestion starts in mouth where salivary glands digest the carbohydrates.
- The food moves from mouth to stomach through alimentary canal known as esophagus. It includes peristalsis movements.
- The stomach mixes the food with digestive juices and move the chyme to small intestine.
- The small intestine mixes the food with juices secreted from pancreas, liver and intestine and pass it to large intestine.
- The large intestine digest the water content from indigested food and pass the reamining to rectum.
- The rectum store the undigested food and excrete it through anus.
Genetic information from DNA to RNA is called transcription which involves the enzyme RNA polymerase. The DNA is read from 3' to 5' in direction and produces an mRNA (messenger RNA) which contains the genetic data from the DNA. This mRNA strand is further processed in the nucleus (capping and adding a poly-A tail) before being transported to the cytoplasm.
The information contained in mRNA is used to make a polypeptide chain is called translation. This involves the use of ribosomes in the cytoplasm which attach themselves to the mRNA strand then using tRNA (transfer RNA) to add amino acids to the elongating polypeptide depending on the codon in the mRNA.
