Macro: DNA/RNA sequences should NOT accept '*' symbols

[AlexeyGirin]

Steps to Reproduce

1. Switch to Macromolecules mode
2. Load by Paste from Clipboard as FASTA - RNA/DNA the following:

   >Should not accept multiplication symbol
   AAAA*AAAA

   

Actual behavior System loads two sequences

Expected behavior Error message should appear: "*" symbol is not allowed for DNA sequence.

As per requirement description (https://github.com/epam/Indigo/issues/1755#issuecomment-1972978475):

DNA/RNA sequences could contain only the symbols: "A", "C", "G", "T", "U", "-"
