Select the Statements That Best Explain Why the End Replication

By Ra_Adeline696 13 Apr, 2022 Post a Comment

Initially the simplest mechanism of DNA replication seemed to be the continuous growth of both new strands nucleotide by nucleotide at the replication fork as it moves from one end of a DNA molecule to the other. Because one strand of a new double-stranded DNA molecule is generated from the old template molecule DNA replication is a semi-conservative process.

Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes.

. This directionality is important for replication as it only progresses in the 5 to. Its used to return results from our databases and no matter how easy that could sound it could be really very complex. To form the phosphodiester bonds this energy is gained by cleaving the triphosphate group of the nucleotide.

Replication occurs at different rates in different types of cells. However since the lagging strand runs in the 5 to 3 direction the chain growth of the newly-synthesizing DNA strand is paused when it reaches the 5 end of the strand. DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end.

At the end of replication the two new segments of DNA each contain one old and one new strand. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. The RNA primer is removed in a 3 to 5 direction.

Answer 1 of 13. 3 DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end. The SELECT statement is probably the most important SQL command.

Helicase opens up the DNA at the replication fork. DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end. After unwinding each side of DNA separates by unzipping down the middle with the two unzipped strands serving as templates for creating new strands.

In transcription DNA serves as the template for RNA synthesis. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. Replication is an essential.

In order to replicate DNA must unwind. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. Initiation of replication occurs within the double helix and rarely at the end.

The statement that best describes the process of DNA replication is DNA replication occurs during interphase and duplicates the amount of DNA in a cells nucleus just prior to cell division. DNA polymerase synthesizes DNA from the 5 end to the 3 end. In this article well give an intro to the SELECT statement and well cover more complex stuff in the upcoming articles.

2 DNA ligase links the 5 OH group of one fragment to the 3 phosphate group of an adjacent fragment. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. In replication the end result is two daughter cells while in transcription the end result is a protein molecule.

DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end. As the DNA opens up Y-shaped structures called replication forks are formed Figure 910. Statements that best explain about the end replication problem exist in eukaryotic chromosome these are - DNA polymerase synthesized DNA from the 5end to the 3 end and DNA polymerase requires a primer for DNA synthesis.

Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. Eukaryotic replication also synthesizes end structures or telomeres. The lagging strand is synthesized from the 3 end to the 5 end.

DNA replications needs a source of energy to proceed ie. Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. The RNA primer is removed in a 3 to 5 direction.

DNA ligase joins the Okazaki fragments together into a single DNA molecule. But because of the antiparallel orientation of the two DNA strands in the DNA double helix see Figure 5-2 this mechanism would require one daughter strand to. But these nucleotide triphosphates hydrolyze.

Two replication forks are formed at the origin of replication and these get extended in both directions as replication proceeds. 1 The RNA primer is removed in a 3 to 5 direction. This area will be the template for replication to begin.

Select the statement that best explains why the replication machinery is found at the replication fork. DNA polymerase may be bulky but it is efficient for DNA replication therefore this would not be the correct answer. Topoisomerase works at the region ahead of the replication fork to prevent supercoiling.

Replication is initiated by DNA polymerase and DNA polymerase δ and є bring about rapid polymerization because of their high processivity. What is DNA replication. DNA is directional in both strands signified by a 5 and 3 end.

The 5 end has a phosphate P group attached while the 3 end has a hydroxyl OH group attached. The replication fork is the position on the DNA double-strand where the unwinding begins. This reaction is just like the conversation on ATP to ADP to AMP.

Then the synthesis of another DNA strand begins at the replication fork. This notation signifies which side group is attached the DNA backbone. The replication machinery must be able to open and stabilize the template DNA and it must have access to both template strands for replication.

It is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA polymerase requires a primer for. Because eukaryotic chromos View the.

ODNA polymerase requires a primer for DNA synthesis. Formation of Replication Forks and Replication Bubbles. Certain proteins bind to the origin of replication while an enzyme called helicase unwinds and opens up the DNA helix.
