The shape of a protein is most directly determined by the

  1.   amount of energy available for synthesis of the protein

  2.   kind and sequence of amino acids in the protein

  3.   type and number of DNA molecules in a cell

  4.   mistakes made when the DNA is copied

Answer and Explanation: 

Proteins are essential molecules in our body that compose most of the tissue. Proteins are made up from amino acids (molecules th...

Many students in their general chemistry classes learn about coordination complexes. Coordination complexes are created when transition metal ions bind to molecules and ions called ligands. . Examples of ligands are: H2O, CN-, NH3, en.

 Transition metals have many unique characteristics due to their partially filled d orbitals. These characteristics are: 1.  Transition metals often have more than one stable oxidation sta...

We should first define all of the answer choices to be able to eliminate and come up with the correct answer. Chromosome functions to carry the genetic information and contains DNA molecules. DNA molecules are the basic building blocks of chromosomes that serve to carry the genetic information. Receptor is a molecule on the surface of cells that receives signals from the extracellular environment and leads to the change...

OH makes a bad leaving group since if it would leave, it would be OH-, a very strong base that is ready to attack. Therefore, we will discuss ways of making OH a good leaving group. What are they? First, we can protonate OH and make it OH2, or water. H2O is a much better leaving group since when it leaves it is very stable and will not go back to attack the molecule. We can protonate OH and make it a good leaving group...

Atomic radius is the  measure of the size of an atom. Atomic radius increases as we go from the right to the left and from the top to the bottom of the periodic table. As we go down the group, the number of energy shells increases and therefore the radius increase. As we go from the left to the right of a period on the other hand, the number of electron shells stays the same while the number of protons increases, theref...

Some of the properties of metals are: 1. High melting and boiling point 2. Malleable (being able to hammered into sheets) 3. Ductile (being able to drawn into wires) 4. Good conductors of heat and electricity Some of the properties of nonmetal are: 1. Low melting and boiling point 2. Do not conduct heat and electricity 3. Brittle 4. Most nonmetals are gases
