Question

Gene expression can occur at several points along the pathway from DNA to RNA to proteins. In one example of gene expression, the protein insulin must be trimmed to a smaller size. How is this is an example of gene expression? Until the protein is trimmed, the ribosomes are not active. Until the protein is trimmed, the shape of the DNA blocks transcription. Until the protein is trimmed, it is not useful to the cell. Until the protein is trimmed, transcription is blocked by a repressor prote

Answer 1

Until the protein is trimmed it is not useful to the cell.

Absolutely sure!

Answer 2

Sequence complete RNA strands directly and in real-time. Or, cDNA ‘strand-switching’ protocol also allows full-length sequencing of cDNA, either with or without PCR amplification.
