Quick Answer: What Is Replication And What Is Its Importance Quizlet?

What is the end result of DNA replication quizlet?

The outcome of DNA replication is two DNA nearly identical DNA double helix molecules.

Each DNA is made up of one DNA strand from the original DNA and a newly created strand..

What is replication of a study quizlet?

A replication study in which researchers repeat the original study as closely as possible to see whether the original effect shows up in the newly collected data. Also called exact replication. See also conceptual replication, replication-plus-extension. Only $2.99/month. ecological validity.

What is the purpose of replication quizlet?

The sole purpose of DNA replication is to generate identical DNA molecules, as they are the blueprint that makes life possible. There are reasons that there DNA replication goes through a slightly different process to repair damage. However, not all the DNA damages can be repaired accurately.

When and where does replication occur quizlet?

DNA replication takes place in the (centrosome / nucleus) of a eukaryotic cell. DNA is replicated during the (M stage / S stage) of the cell cycle. DNA replication needs to occur so that every (cell / organism) will have a complete set of DNA following cell division.

When and where does replication occur?

Replication occurs in the nucleus during the S phase of the cell cycle in eukaryotes, and replication occurs continuously in prokaryotes.

Where does DNA replication start quizlet?

DNA replication will begin at specific sites called origins of replication where the two DNA strands are separated opening up a replication bubble. At the end of each replication bubble is a replication fork.

Where does DNA replication occur?

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.

Why does replication occur?

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

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).

What are the 4 stages of 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.Oct 7, 2019

What 3 things make up DNA?

In turn, each nucleotide is itself made up of three primary components: a nitrogen-containing region known as a nitrogenous base, a carbon-based sugar molecule called deoxyribose, and a phosphorus-containing region known as a phosphate group attached to the sugar molecule (Figure 1).

What is DNA replication and why is it important quizlet?

why is it important that exact copies of DNA are produced during replication? producing exact copies ensures that when a cell divides, the offspring cells will receive the same genetic information as the parent cell. … cancer can result when errors in the replication of DNA in genes that control how a cell divides.

What is replication and where does it occur?

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.

Why is replication of a research study important quizlet?

replication is important because the results of a study can vary considerably depending on experimental conditions and the research method used.

What is a replication of a study?

Replication is a term referring to the repetition of a research study, generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances.

What is replication in an experiment Why is replication important quizlet?

replication means that each treatment is used more than once in an experiment. Important because it allows us to estimate the inherent variability in the data. This allows us to judge whether an observed difference could be due to chance variation.

Why is DNA replication important?

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 does DNA replication mean 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 points where the DNA first are opened are called replication origins.

What is the main goal of 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.

What are the steps of DNA replication quizlet?
