Drip method is one of the mainstays of sustainable agriculture because it : A. reduces soil erosion
Like the name said, Drip irrigation is designed to utilize the least amount of water supply by giving the water to the plant drip by drip. In this method, there is no flow of water that commonly caused the soil erosion (because the water flow cut out the soil little by little)

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,
