Recombination refers to the process by which the fragments of the DNA molecules (either from one or two species) are isolated, cut and inserted into the host strand. The inserted DNA fragment may be directly replicated on its own or through the integration with the host chromosomes.The resulting strand will difer from the old strand.
Answer:
In Eukaryotes, The DNA is so long that it needs to be super coiled to get fit inside the cell.
This process is required in both Eukaryotes and prokayotes. The super coiling and packaging using the DNA binding proteins allows the lengthy molecules to fit inside the cell.
The DNA in the bacterial cell is arranged in several super coiled forms. The over winding of DNA is prevented in bacterial cell by the help of an enzyme known as DNA gyrase which is a type of topoisomerase.
Answer:
There is a 50% chance of getting Huntingdon's disease.
Explanation:
Assume the affected parent is Hh, where H is the Huntingdon's disease allele and h is the unaffected allele. One parent is unaffected, or hh. You have a 50% chance of getting the H allele from the affected parent.
If I had the choice to get tested, for Huntingdon's disease, I would do it. I would want to know so that I wouldn't live my life worrying about it everyday.
Answer:
Hydrogen Bonds Make Water Sticky
Explanation:
Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF). In these molecules, the hydrogen atoms do not pull as strongly on the shared electrons as the N, O, or F atoms. Therefore, the molecules are polar; the hydrogen atoms become positively charged and are able to form hydrogen bonds to negative ions or negatively charged parts of other molecules (such as the N, O, and F atoms that become negatively charged in these compounds).
