Operons are unique to prokaryotic organisms; the genomes of eukaryotic cells do not contain operons. Which of these explains why operons are useful to prokaryotes?
|
Genes encoded by operons are more accessible to RNA polymerase than other genes. |
||
|
RNA polymerase can transcribe more quickly when genes are located within operons. |
||
|
Encoding genes in operons allows the synchronous transcription of genes with related functions. |
||
|
Operons are not highly regulated and this simplicity is an advantage for prokaryotic organisms. |
Homework Answers
Encoding genes in operons allows the synchronous transcription of genes with related functions
Operons are useful to prokaryotes because operons in bacterial cells synchronize the expression of multiple genes by placing them under the control of a shared promoter.

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
