"Cell culture" for those of you on E2020
Four copies of a DNA molecule result from two replications of a single DNA molecule. This is because each replication results in two identical daughter molecules.
Children are the results of a mix of their parent's DNA. They do not have the exact same DNA, they have half their mother's and half their father's. Character and personality play a major part in allowing anyone to identify a person - particularly parents, who spend a lot of time with, and have a lot of opportunity to observe the differences between, their children.
Identical twins have the same DNA - meaning that without the effects of environment they would be identical in every single way.
HIV is a retrovirus that contains two identical copies of single-stranded RNA with a positive polarity. This means that the RNA acts as mRNA and can be directly translated into proteins by the host cell's machinery.
After replication, both prokaryotes and eukaryotes typically have two copies of each chromosome. In prokaryotes, which usually have a single circular chromosome, replication results in two identical circular DNA molecules. In eukaryotes, each linear chromosome is duplicated, producing two sister chromatids that remain attached at the centromere until cell division. Thus, in both cases, there are two copies present post-replication.
By cloning them
By convention, a clone is an engineered offspring derived from the genetic material of a single adult. Identical twins are genetic copies of each other, but they were formed by the splitting of a fertilized zygote rather than by extracting the genetic material of a single adult.
Four copies of a DNA molecule result from two replications of a single DNA molecule. This is because each replication results in two identical daughter molecules.
During cell division, sister chromatids are formed when a single chromosome replicates to create two identical copies. These copies are held together at a region called the centromere, resulting in the formation of sister chromatids.
Identical twins (monozygotic) occur when a single egg, fertilized by a single sperm, splits into two identical halves. Two separate babies with identical DNA are formed. Identical twins are always the same sex and blood type. http://www.twin-pregnancy-and-beyond.com/identical-twins-or-fraternal-twins.html
false thats an easy questionEdited answer:The zygote undergoes somatic cell division to form several identical cells, before differentiation of these stem cells into different tissues and organs. So the answer is TRUE.
Around 7.4 to 7.8 million copies.
A photocopier can make multiple copies of a single page, depending on the settings chosen. Most photocopiers can make up to hundreds of copies in one go.
No. They have to come from the same egg and sperm to have the same DNA (and be identical). Fraternal twins are non identical twins and come from two separate eggs.
Cloning is a process that produces genetically identical organisms by creating copies of an individual's DNA. This can be done through methods such as somatic cell nuclear transfer or gene editing techniques like CRISPR.
