Both because things like car emissions are man made but wild forest fires are natural but the smoke causes pollution as well

Can mRNA coding for a protein destined to be embedded in the plasma membrane associate with rough ER prior to the initiation of

Debora [2.8K]

Answer:

mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.

Explanation:

Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the rough endoplasmic reticulum or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.

The rough endoplasmic reticulum is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins starts in the cytoplasm with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.

Membrane proteins are synthesized in the endoplasmic reticulum and sent to the Golgi complex in vesicles, where it happens the final association of carbohydrates with proteins. Finally, protein is transported from the Golgi complex to its final destiny, the membrane.

If all 5' and 3' splice sites were always used to process the pre-mRNA into mRNA, how many possible distinct mRNA sequences woul

lord [1]

The question lacks the diagram. The diagram has been attached below.

Answer:

Explanation:

Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.

The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.

Thus, the answer is 1.

State the process of carbon cycling

STatiana [176]

Answer:

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
