非数值处理的对象基本上是字符串数据 串( string)(或称字符串) 由零个或多个字符组成的有限序列 记为:s=a1a2an’(n>=0) a;1(1<=i<=n)是字母,数字或其它字符 n称为串的长度,n=0的串称为空串( Null string) 子串一—串中任意个连续字符组成的子序列 包含子串的串叫主串

一、遗传密码 遗传密码(genetic code):是生物蛋白质合成的密码, 是遗传信息的单位,由A、U、C、G组成。 遗传密码又是如何翻译呢? 首先是以DNA的一条链为模板合成与它互补的 mRNA,根据碱基互补配对的规律,在这条mRNA链 上,A变为U,T变为A,C变为G,G变为C 因此,这条mRNA上的遗传密码与非模板DNA链 是一样的,所不同的只是U代替了T。然后再由mRNA 上的遗传密码翻译成多肽链中的氨基酸序列

Positional Number System Number system use positional notation to represent value. The position of the character(numeral) in a character string (collection of possible numerals) indicate value as well as the character itself. Radix (base) is the number of numeral characters in the character set of positional number system. Position Weiaht is a constant that represents the value of a position. Different position has different weight. It is the integer power of radix
