What else can I help you with?
What is term for the two sets of chromatids formed in a parent cell?
sister chromatids (after DNA replication, but before dividing)
The sites where DNA replication and separation occur is called?
The sites where DNA replication and separation occur are called the replication fork, which is formed during DNA replication when the double-stranded DNA is unwound, and the centromere, which is the region of a chromosome where sister chromatids are held together before separation during cell division.
In prokaryotes where does DNA replication occur in the cell?
In prokaryotes, DNA replication occurs in the cytoplasm. The replication process begins at the origin of replication on the DNA molecule and proceeds bidirectionally. Multiple replication fork structures are formed to speed up the replication process.
Is origin of replication or replication fork same?
No, the origin of replication is a specific sequence of DNA where the replication process starts, while the replication fork is the Y-shaped structure formed during DNA replication where the DNA strands are unwound and replicated. The origin of replication initiates the formation of the replication fork.
Many organelles and molecules needed for cell division are formed after DNA replication and before mitosis In which phase are they formed?
The organelles and molecules needed for cell division are formed during the G2 phase of the cell cycle, after DNA replication has occurred during the S phase. This is a crucial preparation phase for mitosis, where the cell ensures it has all the necessary components for successful division.
Why is shapening a pencil a physical change?
no new chemical products are formed .there is only a change in shape .the products after and before are same that is wood and graphite
What is conservative replication in science?
Conservative replication and semiconservative replication are the ways DNA reproduces itself. The difference being whether the newly formed strands pair with each other or with an old one.
What end product is formed during replication?
two identical strands of DNA
Which are formed by reaction?
Reaction products are formed.
Describe the last stage before escape in viral replication?
The last stage before escape in viral replication is packaging of the newly replicated viral genome into newly formed viral particles or virions. This process involves assembling the viral genome with viral structural proteins to form mature virions that can infect new host cells. Once the virions are fully formed, they are released from the host cell, allowing them to spread and infect other cells.
What are the basic three steps of DNA replication?
The three main steps in the process of DNA replication are initiation, elongation and termination. Initiation is the beginning of the process. During elongation new DNA strands are formed and in termination replication ends.
What does the replication fork do in DNA replication?
The replication fork is a structure formed during DNA replication where the parental DNA strands are separated and new complementary strands are synthesized. It allows for the simultaneous synthesis of two new DNA strands in opposite directions. The replication fork moves along the DNA strand as replication proceeds.
