DNA Structure and Replication The higher order structure of DNA shows symmetry, whereas the higher order structures of most proteins do not. Why isn't protein shape more regular like DNA? All of these Some S amino acids cause proteins to bend; others cause protein to flatten. The many different amino acid R groups on proteins confer many different shapes. DNA has one main function in cells whereas proteins have many. All of these Some S amino acids cause proteins to bend; others cause protein to flatten.

DNA Structure and Replication Taylor, Woods and Hughes labeled Vicia DNA by allowing new DNA synthesis in the presence of radioactive thymine. After DNA replication (S phase of the cell cycle), it was observed that only one chromatid of a chromosome was labeled both (a) and (b) both chromatids of a chromosome were labeled neither chromatid was labeled only one chromatid of a chromosome was labeled both (a) and (b) both chromatids of a chromosome were labeled neither chromatid was labeled ANSWER DOWNLOAD EXAMIANS APP
