A DNA molecule consists of two strands of nucleotides twisted together to form a double helix. The sugar-phosphate backbone is found on the outside of this helix and the bases are found braching towards the middle. Hydrogen bonds join the thenitrogenous bases and hold the two strands together.
Therefore your answer is sugar and phosphate.
<span>Teleromes provide a protective cap on the ends of linear chromosomes and are atypical to most prokaryotes, which are circular chromosomes. Teleromes also function as the gatekeepers to prevent topoisomerase enzymes from sliding out of the dna double-helix.</span>
As humans we can do whatever to gentically modify trees, but trees take over 100 years to grow back, to fix this, we could prevent unessecary tree cutting and plant new trees for the next generations , they're renewable because they can be replenished over a course of time

Answer:
Option A
Explanation:
As per the first equation of equilibrium of Hardy Weinberg, the sum of frequencies of alleles at the locus is equal to unity.
Thus,
If "p" represents the frequency of dominant allele, "q" represents the frequency of recessive allele and at equilibrium
Let us assume that value of q is given in question which is equal to 
On substituting the given values in above equation we get -
Hence, option A is correct
