What else can I help you with?
What relation would be your half-sister's half-sister be to you?
You have no blood line relation, You don't share DNA whatsoever. In this scenario putting an example; you and your half-sister share, let's say, the same father but not the same mother and your half-sister's half-sister share the same mother but not the same father. There is no shared DNA between you and your half-sister's half-sister.
What do you call a sister who has a different mother?
If you have a sister with the same dad but different mom, then she's probably your half-sister, although she would have about 25% of the same DNA as yours.
When a double helix DNA is replicated two complete helices are formed together these helices are called sister?
Sister chromatids - two copies of the same DNA joined at the centromere.
How do you know that you have a real brother or sister...Is it based on having the same father or mother?
DNA testing can determine if your brother, sister, father or mother are your true biological ones.
Do sister chromatids always have the same alleles?
Yes, sister chromatids always have the same alleles because they are exact copies of each other formed during DNA replication in the S phase of the cell cycle.
Is it possible to test for maternity between two sisters or can their DNA be the same?
I think this is related... No two people on earth can have the same DNA (genetics) so they wont be the same although they will be simalar though it is possiable to distinguish brother from sister, mother from daughter etc.
How can you tell if brother an sister have same father if father is cemated?
you could have a paternity test. Answer Testing using DNA from the father's father.
How many DNA molecules are in a chromosome just before mitiosis?
Just before mitosis, a chromosome consists of two sister chromatids joined by a centromere. Each sister chromatid contains one DNA molecule. Therefore, there are two DNA molecules in a chromosome just before mitosis.
Did the two DNA molecules have exact copies of each other?
Yes, two DNA molecules that are exact copies of each other are known as sister chromatids and are produced during the S phase of the cell cycle through DNA replication. Each sister chromatid contains the same genetic information as the other.
Can a DNA test be conducted between a brother and a sister who have a common mother to see if they have the same father?
In creation a zygote from a father and mother ..DNA is made from 21 chromosomes from a father and 21 others from amother which the sperm and the ovule contains .. so every zygote from the same mother and father have at least 21 chromosomes common in their DNA because they came from the same source but they will differ in some characters according to the sequences of the bases on The DNA so the answer is yes
IS she mother as DNA result but her sister told her no?
---- == == ---- == == ---- == == ---- == == ---- == ==
How does mitosis ensure that each daughter nucleus receives a complete set of chromosomes?
During the S phase of mitosis (within interphase) DNA is synthesized and replicated making sister chromosomes. The cell then progresses and eventually gets to anaphase, in which the chromosomes get pulled apart by the centromeres holding the 2 sister chromosomes together. This way the daughter cells will have the same exact DNA as the parents cell, one with the same DNA, one with an exact copy.
