• recessive allele expression

• natural selection

• mutation in the genes

NGSS.HS-LS3-2

Which is true from the image?

• exons get expressed

• introns get translated

• the mRNA is an exact copy of the entire gene

• splicing removes telomeres

In the transformation lab, why was an antibiotic used in the plate media?

• to select for bacteria that picked up the plasmid

• to ensure the growth of all bacteria

• to provide nutrients to the growing bacteria

• to keep the plates from melting

What is the purpose of the TATA box?

• it is the promoter region where the RNA Polymerase and transcription factors bind

• it is the enhancer region that will turn the gene on high

• it is the region of DNA where the introns are removed from

• it will be translated into a protein

If the TATA box is not activated what will happen?

• the mRNA will not be made

• the DNA will degrade

• the RNA polymerase will start transcription

• the enhancer regions will combine

When enough tryptophan (trp) is made, how is negative feedback process initiated?

• Trp will activate the repressor

• Trp will attach to the operator

• Trp will bind to the RNA Polymerase

• Trp will block the repressor
