Reading frame of nucleotide sequence
[Menu-bar>Protein>Nucleotide sequence] This Dialog allows to translate coding nucleotide sequences into amino acid sequences.
Three nucleotides are called a triplet and are translated into one amino acid ().
The user specifies a reading direction and can select translated and untranslated sequence regions.
Those parts of the nucleotide sequence that are translated into amino acids are shown in black ()
and untranslated nucleotides are shown in gray (, gion UTRs).
By pressing INSERT, DELETE, SPACE-BAR and BACKSPACE translation of nucleotides is switched on and off.
The cursor keys, HOME, END, PAGE UP/DOWN and the mouse allow navigation within the DNA sequence.
The SHIFT key in conjunction with these keys creates a block selection.
ALT + Cursor left/right jumps to the next interesting sequence position. These positions are intron/exon boundaries and
selected residues or selected amino acids. This is very useful when navigation with the
scroll-bar in a very long nucleotide sequence is difficult.
Above the text field rulers for the nucleotide positions and the translated amino acids are shown.
Residue selections are marked in the rulers.
The horizontal scrollbar outlines the intron-exon structure of DNA.
