A Replication Bubble Is

Question

A replication bubble is:
A) A localized region of DNA strand separation
B) A localized region of RNA strand separation
C) A localized region of DNA strand attachment
D) All of these
E) None of these

Accepted Answer

A replication bubble is a localized region of DNA strand separation that is formed when DNA replication occurs. During this process, the double helix of DNA must be unwound, and each of the two template strands is used to synthesize a new complementary strand. The process begins at a specific site called the origin of replication, and as the two strands are separated, a replication bubble forms. This bubble will continue to grow as the replication process continues until two replication bubbles meet and the entire length of the DNA molecule has been copied.
