Answer:
The correct sequence is
4,1,3,5,2
The anticodon of the tRNA, with its attached amino acid, pairs to the codon of the mRNA, which is attached to the ribosome. The empty tRNA moves off and picks up another matching amino acid from the cytoplasm in the cell. When a second tRNA with its specific amino acid pairs to the next codon in sequence, the attached amino acid breaks from the first tRNA and is bonded to the amino acid of the second tRNA. The ribosome forms a peptide bond between amino acids, and an amino acid chain begins to form. This sequence is repeated until the ribosome reaches a stop codon on the mRNA, which signals the end of protein synthesis.
Explanation:
Translation can be described as a process in which proteins are made by the information coded in an mRNA. Once an mRNA is synthesized, it moves to the ER. In the ER, the tRNA provides anticodons for the codes in a sequential manner. The process comes to an end until a stop codon is reached. The ribosome also forms the essential peptide bonds which are formed so that the amino acids make up a particular protein.
Answer:
The digestive enzymes are secreted from pancreas as inactive form which are called Zymogens or Proenzymes.
Explanation:
Pancreas secretes many Proteolytic enzymes such as Trypsinogen,Chymotrypsinogen.These enzymes undergo cleavage and to produce Trypsin and Chymotrypsin .
The cleavage process is mediated by by enzyne called enterokinase released from mucosal cells of small intestine leading to the formation of active Trypsin .The so formed active Trypsin then carry out both cleavage and activation of rest of the Trypsinogen and Chymotrypsinogen to generate active trypsin and chymotrypsin .
