Question

What is meant by replication being bidirectional? Semiconservative? Continuous and discontinuous?

A) Bidirectional - replication occurs in two directions; semiconservative - new DNA contains one old and one new strand.
B) Bidirectional - replication occurs in one direction; semiconservative - new DNA is entirely old strands.
C) Bidirectional - replication occurs in two directions; semiconservative - new DNA is entirely new strands.
D) Bidirectional - replication occurs in one direction; semiconservative - new DNA contains one old strand and one RNA strand.

Answer 1

Bidirectional replication means replication occurs in two directions, semiconservative replication means each new DNA molecule has one old and one new strand, and discontinuous replication refers to the synthesis of the lagging strand in short fragments.

Step-by-step explanation:

Bidirectional replication means that DNA replication occurs in two directions, starting from a specific point called the origin of replication. This allows for faster and more efficient replication of the DNA.

Semiconservative replication means that each new DNA molecule consists of one parental strand and one newly synthesized strand. This ensures that the genetic information is accurately passed on to the daughter cells.

Discontinuous replication refers to the process of the lagging strand being synthesized in short segments called Okazaki fragments. These fragments are later joined together by an enzyme called DNA ligase.
