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.
举一反三
- More than ___ of all well-studied proteins contain a single structural domain. The members of these single-domain families can have different amino acid sequences but fold into a protein with a similar shape.
- In many lands, the oldest member of a family _________. A: is honoured B: is well-reated C: is cared for by other family members. D: makes logical decisions
- One can predict the amino acid sequence of a protein from the nucleotide sequence of its gene.
- What about inserting a base into the coding region of a gene？ A: No impact B: It will change all amino acid sequences of the protein downstream of the insertion point C: Depending on the insertion point, it may have different effects on the protein D: An amino acid will be inserted into the protein sequence E: Three amino acids will be inserted into the protein sequence
- which of the following is irrelevant to protein bioavailability( ) A: amino acid composition B: protein conformation C: Lignin and proteases D: Millard reactions
