A part of protein sequence that can form a compact three-dimensional structure and often can be independently folded is called ______.
举一反三
- Many proteins can be grouped into protein families, in which each family member has an amino acid sequence and a three-dimensional conformation that closely ________ those of the other family members.
- The misfolded prion form of a protein can convert the properly folded version of the protein in an infected brain into the normal conformation. This allows the misfolded prions, which tend to form aggregates, to spread rapidly from cell to cell, eventually causing the death of the affected animal or human.
- The exact 3D structure of a purified protein can be determined by __________ and ____________.
- One can predict the amino acid sequence of a protein from the nucleotide sequence of its gene.
- Free morphemes can be independently formed into words, and they can also be used as roots to form compounds by adding affixes.
