Definition: The process of a double-stranded DNA being copied to produce an identical double-stranded DNA. Sentence: DNA replication is the basis of heredity. DNA Replication.

What is the definition 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.

What is a replication in an experiment?

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. 1

Why is DNA replication 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 the best definition of replication?

1 : the action or process of reproducing or duplicating replication of DNA. 2 : performance of an experiment or procedure more than once.

What is transcription in biology quizlet?

Transcription. The process of making an RNA copy of a gene sequence. RNA polymerase. An enzyme that synthesizes the formation of RNA from a DNA template during transcription.

What is replicated by a semi conservative process quizlet?

The semiconservative replication of DNA means that a newly formed DNA molecule has one new strand and one strand from the original DNA.

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.

What is the process of replication of DNA?

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. … Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands.

What is involved in replication?

Replication involves the production of identical helices of DNA from one double-stranded molecule of DNA. Enzymes are vital to DNA replication since they catalyze very important steps in the process. The overall DNA replication process is extremely important for both cell growth and reproduction in organisms.

Article first time published on

What is the overall purpose of replication?

The purpose of replication is to advance theory by confronting existing understanding with new evidence. Ironically, the value of replication may be strongest when existing understanding is weakest. Theory advances in fits and starts with conceptual leaps, unexpected observations, and a patchwork of evidence.

What is the main purpose 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.

What is replication in an experiment quizlet?

Replication. Occurs when each treatment is applied to more than one experimental unit; ensures the effect of a treatment is not due to some characteristic of a single experimental unit. Completely randomized design. One in which each experimental unit is randomly assigned to a treatment.

What is replication and randomization?

Through randomization, every experimental unit will have the same chance of receiving any treatment. … Replication is the repetition of experiment under identical conditions but in the context of experimental designs, it refers to the number of distinct experimental units under the same treatment.

What is replication and example?

Replication is the act of reproducing or copying something, or is a copy of something. When an experiment is repeated and the results from the original are reproduced, this is an example of a replication of the original study. A copy of a Monet painting is an example of a replication. noun.

What is a replicate example?

The definition of a replicate is a repeat of something. An example of a replicate is an experiment in cell generation which is repeated. Replicate is defined as to make a copy of, or to fold or bend back. An example of replicate is to copy a drawing from a book.

How does replication occur quizlet?

DNA replication is the process by which DNA is (copied / observed) during the cell cycle. 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.

Why is replication called semi-conservative?

DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.

What is copied during replication quizlet?

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. … During Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase. Interphase is basically the daily life cycle of the cell.

What is codon quizlet?

Codon. a three base mRNA sequence that codes for ONE amino acid. The term is also used for a DNA bases triplet on the non-template strand. As codons are triplets of bases, the number of nucleotides that make up the genetic message must be three times the number of amino acids specified in the protein. mRNA.

What is RNA quizlet?

RNA (Ribonucleic Acid) Definition: a single strand of nucleotides with the bases Adenine, Uracil, Cytosine, and Guanine that also contains the sugar called Ribose. Function: creates proteins, helps with the synthesis of the peptide bond, and helps to transport information throughout the cell. mRNA (messenger RNA)

What is meant by the term transcription?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). … The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

What is RNA replication?

RNA replication is the process by which new copies of genome-length RNAs are made (figure 8). RNA replication occurs in the cytoplasm and is carried out by the viral RNA polymerase.

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.

How does the body replicate cells?

Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. … During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Where does transcription occur in biology?

Steps of Transcription. The process of Transcription takes place in the cytoplasm in prokaryotes and in nucleus in eukaryotes. It uses DNA as a template to make an RNA (mRNA) molecule. During transcription, a strand of mRNA is made that is complementary to a strand of DNA.

What is the end result of replication?

The end result of replication is a doubled DNA. Replication is the simple process of doubling the DNA present in a genome. In this process, an RNA…

Why is replication important to the cell and living organism?

DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. This is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA.
