Activator proteins increase gene expression, whereas repressor proteins inhibit gene expression. which statement concerning activator and repressor proteins in eukaryotes is true? eukaryotes use transcription factors instead of activators or repressors. repressors are more common than activators in eukaryotes. activators are more common than repressors in eukaryotes. activators and repressors are equally common in eukaryotes.

Activators are more common than repressors in eukaryotes.

Explanation:

Eukaryotic transcription is regulated by repressor and activator proteins.

Linked reported genes decrease due to mutation of activator-binding proteins, instead of mutation of a repressor binding site which leads to an increase of the reporter gene.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

atp is used for energy.
