Multiple Choice Questions Set Molecular Biology: DNA synthesis (Replication) DNA replication is a fundamental process in which DNA synthesis occurs, leading to the formation of a new DNA molecule. It is a highly regulated process that ensures the faithful transmission of genetic information from one generation to the next. During DNA replication, the DNA double helix is unwound, and each strand serves as a template for the synthesis of a new complementary strand. The enzyme responsible for DNA synthesis is DNA polymerase, which catalyzes the addition of nucleotides to the growing DNA chain. The process of DNA replication involves a number of key proteins, including helicases, primases, and DNA ligases. 1) In most organisms, DNA is a genetic material that stores the information template for the synthesis of RNA and subsequently protein.  Name the processes a, b, c represented in the figure : 2) In some viruses, RNA serves as the storage of genetic materials and DNA is syn...
