All DNA is composed of a series of nucleotides abbreviated as A, C, G, and T, for example: "ACGAATTCCG". When studying DNA, it is sometimes useful to identify repeated sequences within the DNA. Write a function to find all the 10-letter-long seq…
Given a 2D board containing 'X' and 'O', capture all regions surrounded by 'X'. A region is captured by flipping all 'O's into 'X's in that surrounded region. For example, X X X X X O O X X X O X X O X X After running your function, the board should…
来源:Kerson Huang, Lectures on Statistical Physics and Protein Folding, pp 24-25 把双链DNA解开就像拉拉链.设DNA有\(N\)个链环(link),每个链环有两种状态:闭合着或打开着,后一种状态比前一种状态的能量高\(\Delta\).打开的链环连续地排在一起,闭合的链环连续地排在一起,如下图所示.由于热涨落,链环会自发闭合或打开.问:打开的链环平均有多少? DNA的拉链模型 DNA的可能状态用打开的链环数目标记,\(…

Problem In DNA strings, symbols 'A' and 'T' are complements of each other, as are 'C' and 'G'. The reverse complement of a DNA string ss is the string scsc formed by reversing the symbols of ss, then taking the complement of each symbol (e.g., the re…
Problem An RNA string is a string formed from the alphabet containing 'A', 'C', 'G', and 'U'. Given a DNA string tt corresponding to a coding strand, its transcribed RNA string uu is formed by replacing all occurrences of 'T' in tt with 'U' in uu. Gi…
Problem A string is simply an ordered collection of symbols selected from some alphabet and formed into a word; the length of a string is the number of symbols that it contains. An example of a length 21 DNA string (whose alphabet contains the symbol…
