WebThe most common mutation in cystic fibrosis is the deletion of a single amino acid which results in a misfolded protein. True The set of proteins in a particular cell type is always equal to the number of genes in the genome False . During translation, the rRNA in the large ribosomal subunit acts as an enzyme, linking amino acids together to form a WebThe recognition of misfolded or mutated proteins depends on the detection of substructures within proteins such as exposed hydrophobic regions, unpaired cysteine residues and immature glycans . In mammalian cells for example, there exists a mechanism called glycan processing.
