6 0

Answer: The number of codons in the sequence is 21.

Explanation: A codon is a triplet of nucleotide which codes for a specific amino acid. Each amino acid has at least one codon that codes for it. Three nucleotide residues is required to form a codon and to code an amino acid. Since there are 63 nucleotides in the sequence, the number of codons present in the sequence is 63 divided by 3. 63/3 = 21

Radda [10]

Answer:

Apart from the mentioned functions of a cell membrane, one of the prime functions of a cell membrane is to take part in the communication between the cell and its environment. The cell membrane is one of the most essential components that take part in communication and ensures that the messages are received and decoded appropriately.  

A cell membrane comprises various proteins that plays an essential role in ensuring communication between the cells. These proteins obtain chemical information from other cells known as signaling molecules. When these molecules combine with the cellular membrane’s proteins they stimulate a modification or change in protein conformation, which then transmits the information into the cell and instigates a particular cellular reaction.
