All of the following help the cell regulate gene expression during Step 2 of protein formation EXCEPT
A. general factors that are required for the RNA polymerase to bind to the promoter
B. repressors binding to the operator preventing the RNA polymerase from progressing
C. specialty factors binding to the RNA polymerase, altering its specificity
D. tRNA that binds to the RNA polymerase in the presence of complementary mRNA

All of the following help the cell regulate gene expression during Step 2 of protein formation EXCEPT

specialty factors binding to the RNA polymerase, altering its specificity

Explanation:

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
