Write A Short Analogy To Explain What Replication Is

Where does DNA replication happen?

DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.

Regardless of where DNA replication occurs, the basic process is the same.

The structure of DNA lends itself easily to DNA replication.

Each side of the double helix runs in opposite (anti-parallel) directions..

What is the last step in DNA replication called?

TerminationThis is what we call semiconservative replication. 5) The last step of DNA Replication is the Termination. This process happens when the DNA Polymerase reaches to an end of the strands.

What is DNA replication short answer?

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

What is the first step in DNA replication?

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).

How does DNA replication work step by step?

DNA replication steps. There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell’s nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.

What are the 6 steps of DNA replication?

The complete process of DNA Replication involves the following steps:Recognition of initiation point. … Unwinding of DNA – … Template DNA – … RNA Primer – … Chain Elongation – … Replication forks – … Proof reading – … Removal of RNA primer and completion of DNA strand –More items…

What is the conservative model of DNA replication?

According to the conservative replication model, the entire original DNA double helix serves as a template for a new double helix, such that each round of cell division produces one daughter cell with a completely new DNA double helix and another daughter cell with a completely intact old (or original) DNA double helix …

What binds Okazaki fragments?

Newly synthesized DNA, otherwise known as Okazaki fragments, are bound by DNA ligase, which forms a new strand of DNA. There are two strands that are created when DNA is synthesized.

What two enzymes are needed for DNA replication?

1 Answer. DNA primase and DNA polymerase.

What is the best term to describe DNA replication?

The double helices in each daughter cell consist of one parental strand and one newly synthesized strand. Which term best describes DNA replication? … replication origins. Replication origins typically consist of a small stretch of duplex DNA that is relatively easy to pry apart.

What type of reaction is DNA replication?

DNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. This process takes us from one starting molecule to two “daughter” molecules, with each newly formed double helix containing one new and one old strand.

What is called replication?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. … To accomplish this, each strand of existing DNA acts as a template for replication.

What is an example of DNA replication?

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 4 steps of 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.Oct 7, 2019

Why is replication important?

If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

What is the importance of replication process?

The purpose of DNA replication is to produce two identical copies of a DNA molecule. This is essential for cell division during growth or repair of damaged tissues. DNA replication ensures that each new cell receives its own copy of the DNA.

What are the 7 steps of DNA replication?

The series of events that occur during prokaryotic DNA replication have been explained below.Initiation. … Primer Synthesis. … Leading Strand Synthesis. … Lagging Strand Synthesis. … Primer Removal. … Ligation. … Termination.

What is needed for DNA replication select all that apply?

Answer: The things needed for DNA replication are: … For two identical DNA molecules to be produced, the parent DNA molecule will be unwound by an enzyme known as helicase which breaks the hydrogen bonds between the nitrogenous bases of the two DNA strands thereby separating the two strands.

Which DNA is hardest to separate?

DNA contains four bases – A,T,C, and G arranged with A paired with T and G paired with C on the internal portion of the double helix. Hydrogen bonds stabilize these base pairs – two for the A-T pair and three for the G-C pair. Thus, G-C pairs are harder to break than A-T pairs.

What is the order of enzymes in DNA replication?

Primase (lays down RNA primers) DNA polymerase III (main DNA synthesis enzyme) DNA polymerase I (replaces RNA primers with DNA) Ligase (fills in the gaps)

What is the main goal of DNA replication?

The goal of replication is to produce a second and identical double strand. Because each of the two strands in the dsDNA molecule serves as a template for a new DNA strand, the first step in DNA replication is to separate the dsDNA. This is accomplished by a DNA helicase.
