point mutation has transition (when a purine base is substituted with another purine or pyramidine with pyramidine) or transversion (purine with pyramidine or vice versa) point mutations give rise to silent mutation, nonsense mutation and missense mutation. silent mutations are the least harmful cause their change of the base does not result in anything cause they code for the same amino acid. missense codes for a different amino acid, and nonsense codes for a stop codon.
The carbohydrates produced by plants are an important source of energy for animals. When animals eat plants, energy stored in carbohydrates is released in the process of respiration, a chemical reaction between glucose and oxygen to produce energy (for cell work), carbon dioxide, and water.tarch is the usual form in which carbohydrates are stored as energy by plants. Plants can split starch into its simpler glucose units for use as energy when needed. Cellulose is known as a structural carbohydrate because of the fibers formed by its molecules.
A. amino acids B. glucose C. fatty acids D. nucleotides Question 3 Which of the following best describes a carbohydrate? A. Carbohydrates are organic macromolecules that are made up of carbon, hydrogen, and oxygen atoms and are used for energy storage or as structural molecules.B. Carbohydrates are organic macromolecules that are insoluble in water and have the ability to store energy for extended periods of time.. The shape and folded structure of a protein molecule are important in determining its function. B. Protein molecules are made up of strands of DNA joined together by amino acid sequences. C. The sequence of amino acids that make up a protein molecule do not affect its function.
