Explanation:

Mutation, generally is  a change in nucleotide sequence of the DNA or a gene. This change in nucleotide sequence can result in abnormal encoding of protein sequence, leading to adverse effects on the organism. However, not all mutation produce adverse effects, in fact some mutation provides selection advantage to organisms in the environment.

Mutation occur roughly in 1 in 100,000 to 1 in 1,000,000 nucleotides. A single base or nucleotide change can alter the respective protein and makes it non-functional or cause a disease. Some mutations however, results in the production of the same amino acids or have no effects on the organism. Such mutations are termed silent.

During the process of transcription, DNA strands unwind and a strand is used as a template to form mRNA.

Proteins are polymers of amino acids. They are made up of 2 or more amino acids joined together by a peptide bond.

answer; /// i really don't understand your question/statement.but/lions do fight over territory and breeding rights, sometimes to the death,this is called( i hope this answered your luck

c is the correct answer hope this !
