How do you put DNA sample lengths 3500 in scientific notation?
In scientific notation 3500 is 3.5*10^3
What is Gap Closure methodology?
Its a technique adopted during DNA sequencing in which while joining the contigs we find whether there is any sequence present in between the contigs or not.If there is a sequence inbetween they re sequence the ends of the DNA.If not PCR is used to close the gaps.
In what type of real life situation would the extraction of DNA be useful?
Stem cells in general benefit from being injected with DNA. DNA is used in many crimes to determine who is guilty. For instance, a rape victimcould have skin underneath her fingernails that could be used to identify the perpetrator.
If a sample of DNA contained 20 percent cytosine what percentage of guanine would be in this sample and what percentage of adenine would be in the sample explain?
Umm I'll have to say that your a retard for not knowing it so tuff nubbs who ever made this is stupid because you spelled some words wrong.. The above answer is incorrect, and on a very low evolutionary rung. The correct answer is that with the amount of data provided, it is impossible to tell. If the answer isn't known, it is best to not answer.
What is the function of primers?
RNA primers are used to initiate the DNA replication at the template strand. DNA molecules require a free 3' OH, to which it could add the nucleotides. This free 3' OH is provided by the RNA primer. So prior to the synthesis of DNA a short fragment of RNA is synthesized that is later excised and filled with DNA molecules.
