I am pretty sure the answer is c
F508
it changes the composition of the DNADNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.
DNA is double stranded while RNA is single stranded.
DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
<span>The answer is D. pairs uracil with adenosine instead of thymine. Through the process of elimination, both DNA and RNA contain nitrogenous bases. However, DNA contains sugar deoxyribose within its nucleotide components while RNA contains sugar ribose. Also, DNA has 2 strands wrapped in a helix while RNA has only 1 strand. Thus, the correct choice is D. because RNA pairs uracil with adenosine instead of thymine like DNA.</span>
Answer:
B Low Solar Activity
Explanation:
Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the quaternary.
