Answer:
substitution, missense mutation, and transition
Explanation:
A mutation is any change in the genetic information of an organism. A substitution is a point mutation by which a single nucleotide base pair is replaced by a different nucleotide. Moreover, a missense mutation is a point mutation that results in the incorporation of a different amino acid in the polypeptide chain since this mutation generates a new codon which codes for a different amino acid. Finally, a transition is a point mutation where a purine (either Adenine or Guanine) is changed to another purine, or a pyrimidine (either Thymine or Cytosine) is changed to another pyrimidine (in this case, Cytosine is changed to Thymine).
Answer:
The order of bonds in increasing order of bond strength would be Ionic, peptide, polar covalent, non-polar covalent hydrogen bond.
Ionic bonds are the strongest bonds which are formed by transferring of valence electrons between different atoms. For example, a bond between sodium and chlorine atoms in NaCl.
A peptide bond is a type of covalent bond formed between a carboxylic group of one amino acid and the amino group of another amino acid. It is provided with extra stability through resonance.
A covalent bond is a type of bond which is formed by the sharing of electrons between two atoms.
They bond strength of these bonds is less than that of ionic bonds and more than that of hydrogen bonds.
Hydrogen bonds are weak bonds formed through electrostatic interactions between a proton present in one molecule and an electronegative atom in another molecule.
