描述----------Description----------
Two predefined objects (GENETIC_CODE and RNA_GENETIC_CODE) that represent The Standard Genetic Code.
两个预定义的对象（GENETIC_CODE和RNA_GENETIC_CODE）表示标准的遗传密码。
用法----------Usage----------
GENETIC_CODE
RNA_GENETIC_CODE
Details
详情----------Details----------
Formally, a genetic code is a mapping between tri-nucleotide sequences called codons, and amino acids.
正式，遗传密码，是一个被称为密码子的三核苷酸序列和氨基酸之间的映射。
The Standard Genetic Code (aka The Canonical Genetic Code, or simply The Genetic Code) is the particular mapping that encodes the vast majority of genes in nature.
标准遗传密码（又名规范的遗传密码，或简单的遗传密码）是自然界中的基因编码的绝大多数特定的映射。
GENETIC_CODE and RNA_GENETIC_CODE are predefined named character vectors that represent this mapping.
GENETIC_CODE和RNA_GENETIC_CODE是预定义的命名的特征向量表示此映射。
值----------Value----------
GENETIC_CODE and RNA_GENETIC_CODE are both named character vectors of length 64 (the number of all possible tri-nucleotide sequences) where each element is a single letter representing either an amino acid or the stop codon "*" (aka termination codon).
GENETIC_CODE和RNA_GENETIC_CODE都命名的特征向量的长度为64（所有可能的三核苷酸序列的数量），其中每个元素是一个字母代表一个氨基酸或者终止密码子"*" （又名终止密码子）。
The names of the GENETIC_CODE vector are the DNA codons i.e. the tri-nucleotide sequences (directed 5' to 3') that are assumed to belong to the "coding DNA strand" (aka "sense DNA strand" or "non-template DNA strand") of the gene.
GENETIC_CODE向量的名称，即三核苷酸序列的DNA密码子（导演5至3），被认为属于“编码DNA链”（又名“感DNA链”或“非模板DNA链”）的基因。
The names of the RNA_GENETIC_CODE are the RNA codons i.e. the tri-nucleotide sequences (directed 5' to 3') that are assumed to belong to the mRNA of the gene.
RNA_GENETIC_CODE名称的RNA密码子，即三核苷酸序列（指导5至3），被认为属于该基因的表达。
Note that the values in the GENETIC_CODE and RNA_GENETIC_CODE vectors are the same, only their names are different. The names of the latter are those of the former where all occurrences of T (thymine) have been replaced by U (uracil).
请注意，在价值观GENETIC_CODE和RNA_GENETIC_CODE向量是相同的，只有他们的名字是不同的。后者的名字是前T（胸腺嘧啶）出现的所有那些已经由U（尿嘧啶）取代。

举例----------Examples----------
GENETIC_CODE
GENETIC_CODE[["ATG"]] # codon ATG is translated into M (Methionine)[密码子ATG被翻译成M（蛋氨酸）]
sort(table(GENETIC_CODE)) # the same amino acid can be encoded by 1[相同的氨基酸，可编码1]
# to 6 different codons[6个不同的密码子]
RNA_GENETIC_CODE
all(GENETIC_CODE == RNA_GENETIC_CODE) # TRUE[真]
