(urgent) dna is the primary source of heritable information in cells. explain how the
chemical structure of dna makes this possible.

The DNA is made up of two strands which are joined through the hydrogen bonds present in the nucleotides. There are 4 nucleotides which make up the DNA. Adenine of one strand pairs with thymine of the other strand. Cytosine of one strand pairs with guanine of the other strand. These bonds keep the DNA double helix intact. Information stored in the DNA is unique due to the sequence of pairing of these nucleotides.

The DNA encodes information through the proper sequencing of the nucleotides. These DNA messages encode for certain types of proteins.

answer; i believe the correct answer to the above question is ( friction)

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
