There are two types of twins- fraternal and identical. Fraternal twins are only siblings born at the same time. Identical twins started as 1 egg that split in two after being fertilized. The DNA of identical twins is, well.... identical. At one point, they WERE the same person.
Assuming their are no mutations the twins wold both have 46 chromosomes. Twins, have the normal number of chromosomes, the only difference between an set of identical twins and two average individual is that twins have identical DNA.
The DNA of identical twins and of clones is, apart from random, environmentally produced mutations, 100% identical. The only difference is that clones are produced on purpose through advanced bioengineering techniques while identical twins happen as an accident of nature. Identical twins are, in a sense, natural clones.
By DNA testing is the Only way to be sure
The advantage · DNA fingerprinting is that it's unique · DNA fingerprinting is that it will identify individuals and tell you whose fingerprint it is The disadvantage · For identical twins you have identical DNA and fingerprint · Is slow The advantage · DNA fingerprinting is that it's unique · DNA fingerprinting is that it will identify individuals and tell you whose fingerprint it is The disadvantage · For identical twins you have identical DNA and fingerprint · Is slow
Not unless you're comparing it to your twin's DNA, and even then it only works if you're identical twins.
In identical twins, the DNA is identical, which is what makes them identical. In Fraternal twins it is not.
Identical twins are identical and the egg that they came from split into two giving them the same DNA. Conjoined twins are where the division process is not completed and the embryos remain attached, sometimes sharing organs.
DNA is the blueprint of life. Chromatin is the uncoiled DNA
Chromosomes are the "package" DNA comes in.
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
Junk DNA is non-coding DNA it does not code for protein.
the sequence of certain nucleotides
Chromatins are made up of DNA strands
repeatitive dna is the unit of satellite dna.thats all
Identical twins are the result of a single fertilized embryo splitting in two at an early stage and forming two viable embryos. As such, identical twins have identical DNA. Fraternal twins are the result of two distinct fertilized embryos being viable. As such, they have different DNA. They could even be different sexes.
Yes EVERYBODY has different DNA even if you are identical twins.
DNA helicases are proteins, while DNA molecules are nucleotides.
Generally, each person has his or her own genetic makeup. Identical twins can have a very similar DNA>
The difference between Eukaryotic DNA and bacterial genome replication is the eukaryotic DNA is mostly linear and has multiple sites of replication. They both are bidirectional.
not evenclose, a clone doesn't even have the exact same DNA as the original
Assuming you're referring to twins, identical twins come from the same fertilized cell that broke into two clumps of cells early in its development and so have identical DNA. Fraternal (non-identical) twins come from from two different cells that were fertilized by two separate sperm and while they develop at the same time, they each have unique DNA.
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
All the DNA in one person's body is the same. The only difference is that only certain parts of the DNA are used in each body part
Yes, no 2 people have the same DNA. Except for identical twins. Everyone else in the word has their own unique DNA.
There are differences in both DNA and fingerprints.The Claim: Identical Twins Have Identical DNA
