An animal that does not have the traits to adapt to its surroundings will?
Gennadij [26K]
<h2>It may become endangered </h2>

Explanation: <u><em>If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.</em></u>

Why was it important to determine the structure of DNA to understand how DNA stored, copied, and transmitted information?
dsp73

Answer:

Structure of DNA provides basic information about its packing, replication and copying of the stored genetic information. It tells how the parent DNA strands are copied during the process of cell division.

Explanation:

The double-helical structure of DNA is the basis for its ability to store the genetic information, to replicate itself and to transmit the genetic information. DNA is a polymer of four nucleotides. It stores the genetic information in the sequence of these four nucleotides. The complementary base pairing between the DNA bases tells how DNA template strands are copied during the process of replication.

The newly formed DNA strands have complementary nucleotide sequence to the template DNA strands. Similarly, during the transmission of genetic information, the nucleotide sequence of the DNA is copied into the nucleotide sequence of the mRNA. Therefore, knowledge about the structure of DNA is required to understand its functions.
