Select each hydrocarbon as being saturated or unsaturated, 3-methyloctane, cyclopentene, propane, heptyne, propyne list them into two groups. asap

Solution:

Saturated means that the hydrocarbon has only single bonds and that the hydrocarbon contains the maximum number of hydrogen atoms for each carbon atom. Unsaturated hydrocarbons contain multiple bonding and contain less than the maximum number of hydrogen per carbon.

Saturated hydrocarbon is 3-methyloctane, and propane.

Unsaturated hydrocarbon is Propyne, heptyne, cyclopentene.

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.
