Fundamental Molecule Types in Vector NTI

• Basic Molecules (DNA/RNA/Protein)
• Not built from component fragments
• Sequences and features are either entered by
  users or imported from other databases.
• Constructed DNA/RNA Molecules
• Built from one or more fragments (parent
  molecules, linkers, adapters, etc.)
• Automatically receive the Feature map and
  sequences from the parent molecules.
• Constructed Protein Molecules
• Translated from a coding sequence of a DNA
  molecule
• Does not receive the Feature map from its
  parent DNA molecule

4
Methods of Creating New Molecule in Vector NTI

• Basic Molecules (DNA/RNA/Protein)
• Importing molecules or sequences
• Manually creating new molecules
• Constructed DNA/RNA Molecules
• Splicing exons of an intron-exon join feature
  of another molecules
• Constructing from compatible component
  fragments from other molecules
• Designing from components of a user-defined
  fragments list
• Back-translating from protein molecules from
  components of a user-defined fragments list
• Constructed Protein Molecules
• Splicing exons of a gene
• Translating from DNA molecules

  orientation of the cloned pBR322 fragment in the
  pUC19 recipient
• One of the recipients restriction sites is
  lost after ligation, this gives a mean for
  pre-selecting properly ligated molecule before
  transformation.
• The new restriction site in the recombinant
  molecule that does not exist in the recipient
  allows one to use restriction analysis of the
  clones.
• Vector NTI also recommends oligos or PCR
  primers for clone analysis.
• Vector NTI also lists restriction sites that
  can be used to isolate the closed fragments.
