Answer:
About 26 percent of adult stranded sea lions that die are diagnosed with cancer. Which is high for the population of wild animals. The research finding shows that death of a sea lion with cancer is invaluable. The research shows that sea lion pulp are expose to PCBs while in utero. This is a important health effects in the later life of sea lions,because PCBs can affect organ development.
During the research the Center collects samples from each of these patients to measure environmental exposure to carcinogens,it was discovered that most sea lions were infected with a herpesvirus similar one that causes Kaposi's sarcoma in humans.
Answer:
A. Because of base pairing, each strand has all the information to serve as a template for the other strand.
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two antiparallel polynucleotide chains. This double helix serves as a template for its own duplication. DNA templating refers to the process by which a portion of the DNA molecule in a single strand is used as a template to be copied by complementarity base pairing. According to base-pairing rules, Adenine (A) always pairs with Thymine, while Guanine (G) always pairs with Cytosine (C). These nucleotide bases are each linked with their complementary base by hydrogen bonding. When base pairs separate, the hydrogen bond acceptor and donor groups of each strand allow the addition of nucleotides and synthesis of new DNA strands, a process catalyzed by specialized enzymes (DNA polymerases).
