Explain the function of replication?
DNA replication requires the opening of the 'zipped up' DNA strand. This is so a 'new' strand of DNA can be inserted and have a template strand to 'read' off. DNA polymerase analyses the bases on the template strand and adds each complementary base to synthesise the 'new' strand. In order for DNA polymerase to be able to do this the DNA has to be opened up by helicase to reveal the bases of the template strand. The unzipping of the DNA by helicase forms the replication fork. Thus the function of the replication fork is to reveal template strands for DNA replication to actually occur.
What is used to make a new complementary strand of DNA?
The process of DNA replication.
Difference between DNA replication and transcription?
1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.
Why is DNA replication called a semi-conservative operation?
DNA replication is called a semi-conservative operation because during the process, the two strands of the DNA molecule separate, and each strand serves as a template for the synthesis of a new complementary strand. As a result, each newly replicated DNA molecule consists of one strand that is the original template and one strand that is the newly synthesized strand. This ensures that the genetic information is conserved and passed on to the daughter cells during cell division.
What is the process of DNA replication?
Double Helix unwound and each strand acts as a template. Bases are matched to synthesize the new strand.the DNA molecule splits down the middle, or unzips, into two strands.Veach strand serves as a template or model, to produce the new strands.Vtwo new DNA strands are produced, following the rules of base pairing.a. replication
RNA can manufacture DNA via the action of what?
Reverse transcription is a process where a reverse transcriptase enzyme is used to generate complementary DNA from an RNA template. It is needed for the replication of retroviruses.
What is the explanation for the process of replication?
During DNA replication, the DNA molecule separates into two strands, then produces two new complementary strands following the rules of base pairing. Each strand of the double helix of DNA serves as a template, or model, for the new strand.

What is the complementary DNA strand template strand of atgccatgg?
The complementary DNA strand template of ATGCCATGG is the basic design structure. It determines how the DNA strand will be constructed and the process in which it is formed.
What is used to make a new complementary strand of DNA?
The process of DNA replication.
The process by which DNA is copied to make a complemetary strand of DNA?
DNA replication is a process at which its complementary strands are synthesized. DNA polymerase and other enzymes participates in the catalysis of this process. DNA replication duplicated the total DNA of a cell before mitosis.
What does the word replicate mean involving DNA?
DNA replication, the basis for biological inheritance, is a fundamental process occurring in all living organisms to copy their DNA. This process is "replication" in that each strand of the original double-stranded DNA molecule serves as template for the reproduction of the complementary strand. Hence, following DNA replication, two identical DNA molecules have been produced from a single double-stranded DNA molecule. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication. by: Denfol Gevero

How does DNA copy of itself?
DNA makes copies of itself through the process of replication. Because the nucleotide bases are complementary, they automatically make the other strand of complementary bases when the division of the cell occurs.
What is the process in which DNA is separated into two strands then produces two new complementary strands following the rules of base pairing?
DNA replication
Why is the replication process is a source of few mutations?
Some mutations are due to errors in DNA replication. During the replication process, DNA polymerase chooses complementary nucleotide triphosphates from the cellular pool. Then the nucleotide triphosphate is converted to a nucleotide monophosphate and aligned with the template nucleotide. A mismatched nucleotide slips through this selection process only onece per 100,000 base pairs at most. The mismatched nucleotide causes a pause in replication, during which it is excised from the daughter strand and replaced with the correct nucleotide. After this so-called proofreading has occurred, the error rate is only one per 1 billion base pairs.
How does transcription differ from DNA replication Describe at least four differences?
DNA replication produces a complimentary DNA strand. Transcription produces a complimentary mRNA strand. The major enzyme that carries out DNA replication is DNA Polymerase III (in prokaryotes). The major enzyme that carries out transcription is RNA Polymerase. DNA replication results in two copies of the DNA. Transciption does not affect the DNA - it simply re-anneals (re-joins) after the process. In DNA replication the complementary base to A is T. In transcription the complementary base to A is U.
