The purpose of electron transport systems is to conduct a stepwise release of energy from redox reactions that can be coupled to

work (e.g., extrusion of protons). During electron transfer, a series of non-protein cofactors undergoes reversible reduction and oxidation with small transition states to avoid loss of energy as heat. Which of the molecular features listed below facilitate the low energy transitions mediated by the redox centers?
Choose one or more:
A. coenzyme A (e.g., in Acetyl-CoA)
B. phosphoryl groups with high energy of hydrolysis (e.g., ATP)
C. conjugated double-bond and heteroaromatic rings (e.g., in FMN and NAD+)
D. metal ions (e.g., Fe-S clusters) E. heme groups

A strand of DNA that is 36 nucleotides long codes for how many amino acids?
Margarita [4]

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 <em>first</em>.

36 \ ncltd \ \frac{1 \ codon}{3 \ ncltd} = 12 \ codon\\12 \ codon - 1 \ codon \  = 11 \ codon\\11 \ codons\ \frac{1 A.A.}{1 \ codon}  = 11 \ A. A.

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

thanks,
