The correct answer is: Mutation.

Explanation:

Mutation can be defined as a phenomenon due to which the nucleotide (DNA or deoxyribonucleotide) sequence present in the genome of an organism gets altered.Mutation can occur because of various factors like error-prone replication (DNA polymerase fails to proofread and incorporate the correct nucleotide in the daughter strand), improper DNA repair, exposure to mutagens (that causes mutations like Ultraviolet rays or UV rays that causes the formation of thymine dimer in the DNA), exposure to mobile genetic components like Transposons.The different types of mutations with respect to their effect on the DNA sequence are:Indel mutations: Also called Insertion Deletion Mutations where large sequences of DNA are either incorporated or removed from the genome. If such a mutation occurs in the protein coding region of a gene, then no functional protein can be obtained from such a gene.Base substitution: Here the required nucleotide in the DNA sequence is replaced with some other nucleotide during the process of replication. If this happens in the wobble nucleotide of a codon (the last nucleotide in the triplet codon. A Codon is responsible for encoding for an amino acid. Due to degeneracy of the genetic code, multiple codons can encode for a particular amino acid), that would not affect the protein sequence but if it happens in the other two nucleotide of the codon it can cause change in the amino acid sequence of the protein, resulting in a non-functional protein.Silent Mutation: Where the mutation has occurred either in the non-protein coding region of a gene or in the wobble nucleotide of a codon such the amino acid sequence does not get altered.Non-sense Mutation: Where the mutation is such that a stop codon is introduced in the middle of the protein coding region of a gene. Hence, a truncated non-functional protein can be produced from such a gene.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

Read the following scenario to answer the following question. in some zoos, rare crosses between a male lion and a female tiger have produced hybrid offspring called "ligers." male ligers are sterile but some female ligers are fertile. in the wild, lion and tiger ranges do not naturally overlap, making such a cross unlikely. furthermore, the solitary behavior of tigers and the social organizations of lions create behavioral differences. applying the biological species concept, the sterility of ligers reveals that a. lions are probably a subspecies of tigers b. tigers and lions are the same species c. a new species called "ligers" is forming d. tigers and lions are separate species
