Document Summary
Mass produced, disposable, flexible can fold on itself. Different rna molecules can bind together complementary sequences. Gene segment of dna corresponding to a protein, or its variant proteins. Regulatory dna found across segments that code for proteins. Non-coding regions, bind to proteins that control transcription. Cells far from chemical equilibrium, if approach this, means stops taking energy, dies. Cells need c, n, o, present in atmosphere but in unreactive form. Lots of cells rely on others to fix elements for them. Plants fix carbon, they rely on bacteria for nitrogen. Non coding regions can change through mutations more than coding regions in coding regions, faulty cells die. Differentiation in cells depends on gene expression not changes in cells genome. Changes in gene expression do not rely on changes in dna sequence of corresponding gene. Differentiated cells have lots of proteins in common, rna polymerases, ribosomal proteins. Some proteins can only be found in specialized cells.
