What is the process of DNA replication quizlet?

What is the process of DNA replication quizlet?

DNA replication is the process of producing two identical copies of DNA, in which each template for the synthesis of a new complementary daughter strand. The primers are synthesized by a set of proteins called a primosome, of which a central component is an enzyme primase, a type of RNA polymerase.

Is DNA replication conservative?

DNA replication uses a semi-conservative method that results in a double-stranded DNA with one parental strand and a new daughter strand.

What are the 3 DNA processes?

The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination.

What are the two steps in DNA replication?

• Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.
• Step 2: Primer Binding. The leading strand is the simplest to replicate.
• Step 3: Elongation.
• Step 4: Termination.

What is the first step in DNA replication called?

The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA? molecule. This is carried out by an enzyme? called helicase which breaks the hydrogen bonds? holding the complementary? bases? of DNA together (A with T, C with G).

What is DNA replication example?

When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.2.

What are the 3 major steps in DNA replication?

How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.

What are the three steps in DNA repair?

There are three types of repair mechanisms: direct reversal of the damage, excision repair, and postreplication repair. Direct reversal repair is specific to the damage. For example, in a process called photoreactivation, pyrimidine bases fused by UV light are separated by DNA photolyase (a light-driven enzyme).
