During mRNA synthesis, the unwanted DNA regions are removed and amino acid coding regions are joined by the process of splicing.

Capping: The process of addition of an unusual nucleotide, 7 methyl guanosine to the 5' end of the hnRNA is called capping. It forms a cap-like structure on the 5' end of hnRNA.

Splicing: After capping & tailing now the hnRNA undergoes a process where the non-coding regions, introns are removed and the coding region exons are joined together to form the functional mRNA by the process called splicing.

We can see that in the first step that the smallest number is placed at the leftmost end and the word starting with greatest alphabet is placed at the right most end, with rest of the elements being in the same order.

In second step, the second smallest number is placed at the leftmost end and the word starting with second largest alphabet is placed at the rightmost end with rest of the elements being in the same order.

This process is repeated till an arrangement is achieved where the numbers are arranged in decreasing order from left end and the words are arranged in increasing order (in terms of the letter it starts with) from right end

Using the same pattern, we find the steps of the given input:

Input: 24 sun noon 13 41 milk 53 dark love 16 80 bond

Step I: 13 24 noon 41 milk 53 dark love 16 80 bond sun

Step II: 16 13 24 41 milk 53 dark love 80 bond sun noon

Step III: 24 16 13 41 53 dark love 80 bond sun noon milk

Step IV: 41 24 16 13 53 dark 80 bond sun noon milk love

Step V: 53 41 24 16 13 80 bond sun noon milk love dark

Step VI: 80 53 41 24 16 13 sun noon milk love dark bond

Clearly, ‘love’ is 1^st from right in step IV.

We can see that in the first step that the smallest number is placed at the leftmost end and the word starting with greatest alphabet is placed at the right most end, with rest of the elements being in the same order.

In second step, the second smallest number is placed at the leftmost end and the word starting with second largest alphabet is placed at the rightmost end with rest of the elements being in the same order.

This process is repeated till an arrangement is achieved where the numbers are arranged in decreasing order from left end and the words are arranged in increasing order (in terms of the letter it starts with) from right end

Using the same pattern, we find the steps of the given input:

Input: 24 sun noon 13 41 milk 53 dark love 16 80 bond

Step I: 13 24 noon 41 milk 53 dark love 16 80 bond sun

Step II: 16 13 24 41 milk 53 dark love 80 bond sun noon

Step III: 24 16 13 41 53 dark love 80 bond sun noon milk

Step IV: 41 24 16 13 53 dark 80 bond sun noon milk love

Step V: 53 41 24 16 13 80 bond sun noon milk love dark

Step VI: 80 53 41 24 16 13 sun noon milk love dark bond

Clearly, there are five elements between ‘sun’ and ‘53’ in step I.
