How does DNA replication differ in prokaryotes and eukaryotes?
1. In eukaryotic cells replication forks make several start sites along the DNA strand which forms replication "bubbles" which get larger the more DNA is copied, and stop when DNA replication is complete. In prokaryotic cell's DNA is formed in a loop, two replication forks start along one part of the loop (origin replication) and the replication forks copy DNA in opposite directions until they meet at the other side of the loop, making an exact copy of DNA.
How is translation initiated in cell biology?
The small ribosomal subunit binds to the mRNA The tRNA bearing methionine binds to the start codon , The large ribosomal subunit binds to the small one. The start codon signals the start of translation
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
True or false replication start at one end of DNA molecule and proceeds to the other end?
False: DNA replication starts at origins of replication which can be anywhere on the DNA molecule. Replication is taking place at multiple origins at the same time.
What happens in the stage mitosis?
Mitosis is not the stage. Mitosis is the action which the cell undergoes. The stages of mitosis are: Interphase, Prophase, Metaphase, Anaphase, and Telophase. In these stages the cell splits into 2 identical daughter cells.

What happens first at each origin of a replication?
The enzyme that catalyzes DNA replication is DNA Polymerase. ... This enzyme first binds to a specific site on the DNA known as the origin of ... a single origin on their chromosome while eukaryotes have several on each of ... This is similar to what happens when your coiled telephone cord gets overwound and forms knots.
What separates DNA strands when DNA copies itself?
Topoisomerase is the enzyme that unwinds the DNA during replication. It binds to the DNA, and separates the double strands and form a replication fork. After which the primer bind to the start site, and DNA polymerase starts DNA synthesis.
How is translation initiated in cell biology?
The small ribosomal subunit binds to the mRNA The tRNA bearing methionine binds to the start codon , The large ribosomal subunit binds to the small one. The start codon signals the start of translation
What is meant by ori region in a plasmid?
A site where the Dna replication is initiated. As to start replication ......
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
Where Bacteria RNA polymerase binds to?
RNA polymerase binds to one of several specificity factors, to form a holoenzyme. In this form, it can recognize and bind to specific regions in the DNA.The -35 region and the -10 region comprise the basic prokaryotic promoter, where the RNA Polymerase binds. The DNA on the template strand between the +1 site and the terminator is transcribed into RNA, which is then translated into a protein. At this stage, the DNA is double-stranded ("closed"). This holoenzyme/wound-DNA structure is referred to as the closed complex.
Does DNA replication start at only one place in the DNA?
What do you mean by one area? If by one area you mean does it start at one area then stop and continue on another area then no, DNA replication is continuous and when it takes place it is the most important thing going on in the cell. The cells resources are directed at this process * DNA replication means copying the entire DNA molecule, so it involves the entire molecule, but not all at the same time. In bacteria (prokaryotic cells) replication begins at one point in the molecule and continues all the way round the circular molecule.Beginning at just one place would take too long in eukaryotic cells; someone has calculated that our longest chromosomes would take about a fortnight to replicate, and we cannot wait that long! So replication begins at a number of sites along the length of the DNA molecule. At each replication site, as the DNA strands are separated there is a bulge in the molecule called a replication bubble. As replication proceeds these bubbles become longer, and eventually they merge into one another and the job is done.
What is the time between the end of cell division and the start of DNA replication?
yup!
What science words start with a p?
photosynthesis, physical change, photon, photoelectrons, prokaryotic cell
True or false replication start at one end of DNA molecule and proceeds to the other end?
False: DNA replication starts at origins of replication which can be anywhere on the DNA molecule. Replication is taking place at multiple origins at the same time.
Produces The RNA primer required for DNA replication to begin?
the chemical primase produces the rna primer to start DNA replication. the primase is later removed and replaced with DNA by a repair polymerase
