Why do chromosomes need to become 2 strands before the cell divides?
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
What are the parts of a organelle called?
There are several different organelles in a cell. For example: nucleus ribosome rough endoplasmic reticulum Golgi apparatus smooth endoplasmic reticulum Each one has different parts so you need to be specific and say which organelle you are asking about
Why does the body need to produce many different kinds of antibodies?
By definition, antibodies act against particles, proteins, microbes, and viruses. Each antibody has to be a "match" or a "fit" to work against what it is working on. So if you have had chicken pox, you made antibodies to act against it and inactivate it. If you are exposed again, you will not get it. If you get a blood transfusion it must match or your antibodies will inactive it and will cause a reaction that will hurt you. Think of all the things you have come across: different pollen from different plants, different colds, different flu (you have to get a new shot every year as it is different), different vaccines. It just goes on and on.
Why is it important for DNA is replicated before a cell divides?
so that there will be two sets of DNA ... one for each new cell. If the DNA doesnt replicate one new cell would have no DNA. and cells need DNA.
Are cells the basic unit of living things?
Not really because each cell is surrounded by a membrane and also that every cell contains a nucleus.You need to be a student of truth before you will understand what is nucleus.
What cells produce antibody?
T plasma cells, if your at A level or anything lower, you don't need to write anymore than that. T plasma cells are formed through clonal selection.
Why do each pathogen need a specific antibody?
each pathogen has a antigene which the antibodies attach to so each pathogen needs a unique antibodie
Why limiting dilution is used in hybridoma technology?
limiting dilution is a method used to have a single cell / well in a tissue culture plate. and why we need a single cell / well ...to ensure that we have single clone of antibody producing B cell as during any immuneresponse a mixed of different B clone will produce to make antibodies against foreign antigen even during the 2ndary immune response the antibodies produced will have different structure in the variable region because of somatic hypermutation process during affinity maturation at the germinal center. Thus, we do a limiting dilution to study each B cell clone antibody produced individually and test its specificity by ELISA, which can be easy to detect the best affinity binder clone and chose it for further steps.
Do you need a different copyright for each work that you do?
Do I need to submit a different copyright application for each work that I do.
What is durability of Energizer cell?
This depends on the type of battery being used. Each of them come with a different voltage so you will need to have that information before continuing.
What does a living cell need?
different living cells need different things, but all of them need a source of eb=nergy at the least.
Why polyclonal antibody solution is able to precipitate its antigen protein whereas monlclonal antibody solution has hard time to do so?
Polyclonal antibody recognizes several epitopes on the target protein while monoclonal antibody recognizes only single epitope. Sometimes, monoclonal antibodies are not able to precipitate the antigen because the epitope might need to be exposed on the surface of the antigen to be recognized by the antibody. Since the epitope might be hidden and it's a single epitope that is recognized by the monoclonal antibody, the propability of the antibody to reconize the epitope is lower compared with the polyclonal antibody that recognizes several epitopes on the target protein.
Where could I find a guide explaining how to add or change cell phone ringtones?
Each cell phone is different so you will need your particulars models instruction. In most cases the owners manual is available online at the manufacturers website.
Why different buyers need cellpnones?
i need answers like i need a cell phone to talk to my friend and others
Why does a cell that has a cell wall need a cell membrane?
Cell walls and cell membranes have different purposes in a plant cell, the cell wall is for support structure and in some cases protection, where as the cell membrane has many different jobs for the cell, which the cell wall don't perform, such as regulating the flow of what enters and exits the cell .
How many chromosomes are there in each daughter cell after mitosis?
There are 46 chromosomes or 23 pairs of chromosomes in each daughter cell after mitosis. Each daughter cells need 46 or 23 pairs of chromosomes to work properly and survive.
Why do chromosomes need to become 2 strands before the cell divides?
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
