Explanation:
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
Answer:
Fragment B has a higher C/G base pair content.
Explanation:
DNA denaturalization happens when the double helix melts and the result is <u>two single strands</u>. The separation occurs because the hydrogen bonds between the bases, break apart.
DNA denaturalization occurs faster in the regions where the interaction between the two strands is weak, <u>A/T rich regions</u>. On the other hand in <u>C/G rich regions</u>, the strand is held together more strongly hence, it takes more time for it to break apart.
DNA with a lot of A/T base pairs denatures at 158 °F (70°C) and DNA rich with C/G base pairs denatures at over 212 °F (100°C). C≡G base pairs have three hydrogen bonds, the bond is very stable and needs a lot of energy to be dissociated. <u>The higher the C≡G base pairs content, the higher the melting point of the DNA.</u>
