When does exon shuffling occur? a. during splicing of dna b. during mitotic recombination c. as an alternative splicing pattern in post-transcriptional processing d. as an alternative cleavage or modification post-translationally e. as the result of faulty dna repair?

The correct answer is C.

 Exon shuffling occurs as an alternative splicing pattern in post-transcriptional processing.

Exon shuffling is termed as a molecular mechanism which is formed of new genes. Two or more exons which are of different genes can be brought together ectopically.
 Exon shuffling can occur in cross over during sexual recombination of illegitimate recombination and parental genomes, transposon-mediated exon shuffling. Exon shuffling follows certain splice frame rules.

Glucose, also called grape sugar, blood sugar or corn sugar, is among the simplest and one of the primary naturally occurring sugars. produced naturally by plants as the primary photosynthesis product, it is heavily used by living beings as a main energy source and is necessary for cellular respiration. chemically, it is a monosaccharide carbohydrate and serves as a building block for complex sugars like starch.
