rosalind练习题二十二
# Problem
# After identifying the exons and introns of an RNA string, we only need to delete the introns and concatenate the exons to form a new string ready for translation.
# Given: A DNA string s (of length at most 1 kbp) and a collection of substrings of s acting as introns. All strings are given in FASTA format.
# Return: A protein string resulting from transcribing and translating the exons of s. (Note: Only one solution will exist for the dataset provided.)
# Sample Dataset
# >Rosalind_10
# ATGGTCTACATAGCTGACAAACAGCACGTAGCAATCGGTCGAATCTCGAGAGGCATATGGTCACATGATCGGTCGAGCGTGTTTCAAAGTTTGCGCCTAG
# >Rosalind_12
# ATCGGTCGAA
# >Rosalind_15
# ATCGGTCGAGCGTGT
# Sample Output
# MVYIADKQHVASREAYGHMFKVCA
# 给出一段序列，给了2个内含子序列，需要将2个内含子去掉，将剩余的序列转录为RNA，翻译成蛋白质。
