Early work in molecular genetics suggested the model that one gene makes one protein. This model has been refined since the discovery of genes that can encode multiple proteins by alternative splicing and coding sequences split in short section across the genome whose mRNAs are concatenated by trans-splicing.

QSN1 What model did early work in molecular genetics suggest? ANS1 the model that one gene makes one protein. QSN2 What discovery caused the model that one gene makes one protein to be refined? ANS2 the discovery of genes that can encode multiple proteins QSN3 How do genes encode multiple proteins? ANS3 by alternative splicing and coding sequences QSN4 How are alternative splicing and coding sequences distributed? ANS4 split in short section across the genome QSN5 In order for a gene to encode multiple proteins, how must its mRNAs be arranged? ANS5 concatenated by trans-splicing.
