Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
62 -- The roots absorb water for the plant, and also provide it with stability, ie to keep it from falling over.64 -- Structure B is a leaf, and a leaf's main function is to take in sunlight and perform photosynthesis, which makes food for the plant.
B is false, enzymes speed up the reaction by lowering the activation energy needed for the reaction to start.
Answers B
Answer:
Is D
Explanation:
Nucleic acids are giant biomolecules made of monomers called nucleotides. Nucleotides have three components: pentose sugar (5-carbon sugar), phosphate group, and nitrogenous base.
