Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
Answer:
The very bottom one
Explanation:
Thymine and Adenine always pair together while cytosine and guanine go together.
Folds are bends in rocks whereas faults are displacements of rocks that were once connected to a fault line.

<span>''Psychologists use memory models to think and communicate about memory. Information-processing models involve three processes: encoding, storage, and retrieval. The connectionism information-processing model views memories as products of interconnected neural networks. The three processing stages in the Atkinson-Schiffrin model are sensory memory, short-term memory, and long-term memory. More recent research has updated this model to include two important concepts: (1) working memory, to stress the active processing occurring in the second memory stage; and (2) automatic processing, to address the processing of information outside of conscious awareness.''</span>
