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 an example of gene expression?

These products are often proteins, but in non-protein coding genes such as  Several steps in the gene expression process may be modulated, including the  The stretch of DNA transcribed into an RNA molecule is called a transcription unit 

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

The answer would be b. it is a learned trait
