Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes.
Proteins are the main structural and functional components of cells.
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid. The mRNA sequence is thus used as a template to assemble in order the chain of amino acids that form a protein.
The sequence of a protein is determined by the DNA of the gene that encodes the protein change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.

Answer:
ATP consists of an adenosine molecule
bonded to three phophate groups in a row.
In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP.
This occurs when a molecule of adenosine diphosphate (ADP) uses the energy released during cellular respiration to bond with a third phosphate group, becoming a molecule of ATP. So the energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP. When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy.
