Answer:

See answer below

Explanation:

Hi there,

Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons first.

Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

thanks,

drawing upon the results of this exercise, why is pseudomonas aeruginosa of such concern in burn patients chegg

Agata [3.3K]

Pseudomonas aeruginosa is of concern in burn patients beacuse it can cause infections like AIDS,diabetes mellitus , etc.

Pseudomonas aeruginosa is a common bacteria that can be found in soil, water, and other environmental niches. Burn wounds are intricate microenvironments where bacterial pathogens like P. aeruginosa can cause infections. Typical virulence factors like pyocyanin and pyoverdine expressed at higher levels than they would have under conventional laboratory conditions.

Elastase is secreted as well, is primarily responsible for the host tissues' degradation. P. aeruginosa infections cause severe consequences mostly in organisms with weakened natural defences. Examples of these circumstances include burn wound patients.

An unlabeled hierarchical diagram of various astronomical bodies is shown. The labels A, B, C and D can be used to represent the

Sliva [168]

Answer:

Part 1:

The four astronomical bodies one could choose to represent the 4 labels in the diagram are

A - universe

B - galaxy

C - solar system

D - Mars

The universe contains galaxies and galaxies holds solar systems which have planets like Mars

Part 2: D or a planet like Mars is unlike all their other astronomical bodies it does not have other astronomical bodies within it thus, its different from rest.
