In samples of DNA isolated from two unidentified species in bacteria, X and Y adenine makes up 32% and 17%, respectively, of the
Vikki [24]

Answer:

On the basis of Chargaff's rule, in a double-helical DNA, A = T and G = C (Here A means adenine, T means thymine, G means guanine, and C means cytosine. For X, A is given 32%, therefore, T must be 32%, and the leftover 36% is to be distributed equally between G and C. Thus, G = C = 18% each.  

The assumption formed is that the DNA is a double-stranded structure. The species that exhibits higher G + C content in the molecule of a DNA is steadier at higher temperatures as it melts at high temperature. The species Y, which exhibits G + C in total as 66% is the thermophilic bacterium between the two.

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,
