Suppose you are an astronomer, and a child asks you to explain how long it takes light to travel through space. In your own word

s, answer the child's question. Be sure to mention the speed that light travels in space, and provide a general idea of how long it takes the light from distant stars to reach Earth.

Ok so I would start by saying that light has a maximum speed, then explain that because space is so big we measure it's distance in light years and which means how light travels in a year at 186,282 miles per second Put that in perspective my saying If you could travel at the speed of light, you could go around the Earth 7.5 times in one second. Tell them Sunlight takes about 8 minutes 19 seconds to reach the Earth and that it can take millions or more light years for more distance stars light to reach our telescopes .

The role of BiP in protein folding was briey described in this chapter. Answer the following questions
NISA [10]
<h2>KDEL Sequence & Protein Unfolding</h2>

Explanation:

(a) The distinction between proteins sent out from and those held in the ER has all the earmarks of being represented by two unmistakable sorts of focusing on successions that explicitly mark proteins as either bound for transport to the Golgi or bound for maintenance in the ER. Numerous proteins are held in the ER lumen because of the nearness of the focusing on grouping Lys-Asp-Glu-Leu (KDEL, in the single-letter code) at their carboxy end. In the event that this succession is erased from a protein that is regularly held in the ER (e.g., BiP), the transformed protein is rather moved to the Golgi and emitted from the cell. On the other hand, the expansion of the KDEL arrangement to the carboxy end of proteins that are typically discharged makes them be held in the ER. The maintenance of some trans membrane proteins in the ER is comparatively directed by short C-terminal successions that contain two lysine deposits (KKXX sequences)

(b) Proteins are large molecules composed of folded chains of amino acids. Every protein has a unique shape and that shape determines the things it does. You could think of them as keys that fit into certain locks around the body Proteins do lots of different things around the body, including speeding up biological processes, recognizing antibodies, providing structure to certain body parts, transporting substances, regulating genes, and responding to signals inside and outside the body Proteins range in size from small ones, such as insulin - only 51 amino acids long, to extremely large ones, such as titin almost 27,000 amino acids long. No matter their size, they must be folded into a particular shape in order to function. Sometimes, though, things go wrong and cause the protein to unfold

The primary mRNA transcript is edited much as you edit a research paper before submitting it. Which of the following editing pro
sergeinik [125]

Answer:

<h2>Cross out unnecessary phrases: Cut out introns.</h2>

Explanation:

The mRNA is a transcript of DNA . Primary mRNA transcript is edited before translation.

Mature mRNA is transcribed into protein, which is the final product of central dogma.

mRNA contains introns and exons , introns are removed by splicing.

the analogy of mRNA editing is Cross out unnecessary phrases: Cut out introns.
