1. gene regulation in eukaryotes (1 point)
usually involves operons.
is simpler than in prokaryotes.
allows for cell specialization.
includes the action of an operator region.
2. specialized cells regulate the expression of genes because they (1 point)
do not want the genes to become worn out.
cannot control the translation of proteins.
do not carry the complete genetic code in their nuclei.
do not need the proteins that are specified by certain genes.
3. what is one difference between transcription factors and mirna (interference rna)? (1 point)
mirnas are mobile chemical messengers, while transcription factors are not.
transcription factors work at halting transcription, while mirnas work at destroying the products of transcription.
mirnas bind to dna, while transcription factors do not.
transcription factors control eukaryotic gene regulation, while mirnas control prokaryotic gene regulation.
4. why does it take only a few homeotic genes to control the development of a eukaryote? (1 point)
because each homeotic gene begins a cascade of events that leads to the formation of a specific body part
because eukaryotes have surprisingly small numbers of genes in any one cell
because each cell receives only a fraction of the total number of genes in the organism
