Coding sequence

Coding Sequence (CDS): 4443 bp within the mRNA code for the amino acid sequence of the gene's protein product.

Coding sequence: The portion of a gene or an mRNA which actually codes for a protein. Introns are not coding sequences; nor are the 5' or 3' untranslated regions (or the flanking regions, for that matter - they are not even transcribed into mRNA).

Primary (initial) mRNA transcripts in eukaryotic cells are synthesized as larger precursor RNAs that are processed by splicing out introns (non-coding sequences) and ligating exons (non-contiguous coding sequences) into the mature mRNA.

Eukaryotic DNA contains both exons (coding sequences) and introns (intervening sequences). In eukaryotic cells this DNA is used as a template for the production of mRNA, which must then undergo mRNA splicing.
Full article >>>

A mutation which adds or deletes one or two base pairs (or any non-multiple of 3) from a coding sequence in a molecule of DNA, so that the genetic code is read out-of-phase.

Point mutations that occur in non-coding sequences are most often without consequences, although there are exceptions. If the mutated base pair is in the promoter sequence of a gene, then the expression of the gene may change.

If the sequence is altered by snipping or swapping the result is likely to be fatal because the coding sequence [the readout in terms of triplets] will be messed up.

The DNA base sequence interrupting the protein-coding sequences of a gene; intron sequences are transcribed into RNA but are cut out of the message before it is translated into protein.

Almost half the DNA in eukaryotic cells is repeated nucleotide sequences. Protein-coding sequences are interrupted by non-coding regions. Non-coding interruptions are known as intervening sequences or introns.

Moreover, the genes are often fragmented internally by non-coding sequences called introns, which can be many times longer than the genes themselves. Introns are removed on the heels of transcription by splicing.
