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.
Solved The End Replication Problem Telomere Problem Exists Chegg Com
It is due to difficulty in unwinding the DNA template for replication.
. As the DNA opens up Y-shaped structures called replication forks are formed Figure 910. Expert Answer 100 32 ratings 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. DNA polymerase synthesizes DNA from the 5 end to the 3 end.
DNA ligase joins the Okazaki fragments together into a single DNA molecule. Therefore saying that the SELECT statement is the most important one is not true. Indicate whether the following statements are true or false.
The lagging strand is synthesized from the 3 end to the 5 end. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. If a statement is false explain why it is false.
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. 3 DNA ligase links the 5 OH group of one fragment to the 3 phosphate group of an adjacent fragment.
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. It is due to the nature of the DNA polymerase which can only add new nucleotide at the 3 end. Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA.
It is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The RNA primer is removed in a 3 to 5 direction. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes.
Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes. DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end. Topoisomerase works at the region ahead of the replication fork to prevent supercoiling.
Thus this is the main difference between leading and lagging strand. In replication the end result is two daughter cells while in transcription the end result is a protein molecule. Its as important as others are but its definitely most commonly used.
View the full answer. 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. DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end.
The replication fork is the position on the DNA double-strand where the unwinding begins. 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. Nonhomologous end joining is a mechanism that ensures that DNA double-strand breaks are repaired with a high degree of fidelity to the original DNA sequence.
Then the synthesis of another DNA strand begins at the replication fork. A problem known as the end-replication problem telomere problem exists in eukaryotic chromosomes wherein the chromosomes shorten with each round of DNA replication. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes.
Replication is an essential. Select all that apply A. All SQL commands are important and needed especially these 4 most commonly used SELECT INSERT UPDATE DELETE.
It is due to antiparallel nature of the DNA molecule. 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. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes select all statements that apply 1 The RNA primer is removed in a 3 to 5 direction.
DNA polymerase requires a primer for DNA synthesis DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end. It is due to the semiconservative nature of DNA replication. What is DNA replication.
DNA polymerase requires a primer for DNA synthesis. Not all events will be placed. Certain proteins bind to the origin of replication while an enzyme called helicase unwinds and opens up the DNA helix.
2 DNA polymerase requires a primer for DNA synthesis. Two replication forks are formed at the origin of replication and these get extended in both directions as replication proceeds. SELECT statement Syntax.
DNA polymerase synthesizes DNA from the 5 end to the 3 end. Helicase opens up the DNA at the replication fork. Select the statements the best explain why the end-replication problem exists.
Leading strand refers to one of two strands of DNA found at the replication fork being replicated continuously while lagging strand refers to the other strand found at the replication fork replicating discontinuously in the 5 to 3 direction. Being able to write a SELECT to get. Order the events in which telomerase maintains chromosomal ends during replication.
DNA polymerase requires a primer for. ODNA polymerase requires a primer for DNA synthesis.
