I believe the waste product of respiration in animals is carbon dioxide and water.
Hope it helps!
Answer:
The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures
Explanation:
A form of feedback regulation controls the trp operon by regulating transcription termination, a mechanism referred to as Attenuation.
-In the presence of high concentrations of tryptophan, RNA polymerase ceases transcription shortly after initiation in a region called the leader sequence.
-If the concentration of tryptophan is low, transcription does not terminate until the entire operon is transcribed. The mechanism of attenuation links alternative RNA secondary structures to transcription termination.
-Immediately after transcription, RNA from the leader region folds into one of two alternative secondary structures.
-One of these structures is a transcription termination signal that stops RNA polymerase from continuing to the end of the operon.
-The alternative structure does not contain a transcription termination signal and allows transcription of a single mRNA that encodes all the structural genes.
-The decision as to which of the two alternative RNA structures formed is regulated by the concentration of tryptophan.
The milky way is a spiral galaxy.
Answer: Option E.
The cytosolic face of the plasma membrane.
Explanation:
Endoplasmic recticulum is a membranous organelles in cytoplasm that help in synthesis,transport and modifications of proteins. Proteins are transported to golgi apparatus while some remain in endoplasmic reticulum. Proteins are transported from ribosomes on rough endoplasmic recticulum to rough endoplasmic recticulum lumen which is the site of protein modifications, then to golgi aparathus.
- Biology Definition: Respiration is a chemical reaction that happens in all living cells. (Both plant cells and animal cells). Respiration is the way that energy is released from glucose so that all the other chemical processes needed for life can happen.
- Normal definition: The action of breathing, also called ventilation.
