The genetic code is the set of rules used by living cells to ... Reading frames in the DNA sequence of a region of the human mitochondrial genome coding for ...
[1] [2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs protein synthesis. [2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as ...
When translating from genome to protein, the use of the correct genetic code is essential. The mitochondrial codes are the relatively well-known examples of variation. The translation table list below follows the numbering and designation by NCBI. [ 2 ]
Some types of non-coding DNA are genetic "switches" that do not encode proteins, but do regulate when and where genes are expressed (called enhancers). [32] Regulatory sequences have been known since the late 1960s. [33] The first identification of regulatory sequences in the human genome relied on recombinant DNA technology. [34]
