B. thee nucleotides that code for an amino acid
C. a translated unit of DNA
D. a sequence of nucleotides in RNA that codes for a functional product
3. This type of protein binds near the promoter region of genes to activate transcription
A. RNA polymerase
B. activators

D. co-repressors
E. all of the above does bind
Homework Answers
1. Option C "TOPOISOMERASE". Topoisomerases are enzymes that are responsible for the introduction and elimination of supercoils. Positive and negative supercoils require two different topoisomerases. This prevents the distortion of DNA by the specificity of the topoisomerases.
2. Option A "A segment of DNA that contains inherited information that defines the structure of a protein or RNA"
3. Option A "RNA polymerase".

3. This is a schematic of a very simple pattern of gene expression. Yes means the protein is present and can bind the promoter. No means the protein is absent. Transcription factors are proteins that help regulate transcription by binding DNA Activators are transcription factors that help transcription. For example, they bend the promoter and make it accessible to RNA polymerase. Repressors are transcription factors that inhibit transcription. For example, they might bind the promoter and stop the RNA polymerase...
