Use the complementary rule: If we had a DNA strand of 20 nucleotides, and 6 of them

polet [3.4K]

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

20. Does facilitated diffusion require energy for the cell?

Vera_Pavlovna [14]

Answer: no

Explanation: The solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. This process is called passive transport or facilitated diffusion, and does not require energy.

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,
