Do you NÉE replication produces two identical DNA molecules called?
Meiosis – 1 DNA replication produces two identical DNA molecules called sister chromatid(s which separate during mitosis 2 After chromosomes condense | Course Hero. You can ask !
What are the two identical DNA molecules in a replicated chromosome?
In replication, the DNA molecule is copied, and the two molecules are known as chromatids. During the later stages of cell division these chromatids separate longitudinally to become individual chromosomes. Chromatid pairs are normally genetically identical, and said to be homozygous.
What is the region where the identical DNA molecules are most tightly attached to each other?
centromere
What occurs after chromosomes condense?
Mitosis is the process of nuclear division, which occurs just prior to cell division, or cytokinesis. During this multistep process, cell chromosomes condense and the spindle assembles. Each set of chromosomes is then surrounded by a nuclear membrane, and the parent cell splits into two complete daughter cells.
What is it called when a cell has two complete sets of chromosomes?
A diploid cell is a cell that contains two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be a homologous chromosome set. A homologous chromosome pair consists of one chromosome donated from the mother and one from the father.
How often does DNA replication occur?
50 pairs per second
What is DNA replication in prokaryotes called Why?
Prokaryotic DNA Replication is the process by which a prokaryote duplicates its DNA into another copy that is passed on to daughter cells. Replication is bi-directional and originates at a single origin of replication (OriC). It consists of three steps: Initiation, elongation, and termination.
How do prokaryotes replicate their DNA?
DNA Replication in Prokaryotes: A replication fork is formed when helicase separates the DNA strands at the origin of replication. The DNA tends to become more highly coiled ahead of the replication fork. DNA ligase seals the gaps between the Okazaki fragments, joining the fragments into a single DNA molecule.
How many DNA polymerases are in prokaryotes?
five different
Why is DNA polymerase 1 used in prokaryotes?
DNA polymerase I (or Pol I) is an enzyme that participates in the process of prokaryotic DNA replication. The physiological function of Pol I is mainly to repair any damage with DNA, but it also serves to connect Okazaki fragments by deleting RNA primers and replacing the strand with DNA.
What is the leading strand in DNA replication?
One new strand, which runs 5′ to 3′ towards the replication fork, is the easy one. This strand is made continuously, because the DNA polymerase is moving in the same direction as the replication fork. This continuously synthesized strand is called the leading strand.
What is the process of DNA replication called?
The process of DNA duplication is called DNA replication. Replication follows several steps that involve multiple proteins called replication enzymes and RNA. In eukaryotic cells, such as animal cells and plant cells, DNA replication occurs in the S phase of interphase during the cell cycle.
