Answer: Chromosome
The polynucleotide DNA strands are wrapped on circular proteins called histones which then are condensed into a structure called chromosome.
Three nonpolar molecules that are used in everyday live are carbon dioxide (CO2), methane (CH4), and ethylene (C2H4).
Ethylene is used to make plastic and ripen fruits and methane is used to produce electricity and power garbage trucks. Besides its usage in the crucial processes of photosynthesis and cell respiration that keep us alive, carbon dioxide is important in refrigeration and is also found in fire extinguishers.
Hope this helps!
No, because DNA is a natural fact of a humans body.
Movement : kinesis
Behavior: It is sometimes called a roly-poly due to its ability to roll into ball when disturbed
Answer:
Western blot should be performed
Explanation:
Generally ELISA test is sensitive to elevated antibodies levels in the blood. Because HIV infection is characterise with increases in antibodies levels(HIV-antibodies levels)of the body, it is usually the first screening test for HIV,however it is also sensitive to elevated antibody from any other infection apart from HIV. Therefore for confirmation, the procedure is to run a second ELISA test, to determine if the antibody rise was due to HIV or not. If the second test turns positive, then Western blot can be applied.
The Western blot through secondary and primary antibodies binding , separates the investigating antibodies, and identity the specif HIV antibodies present to give a positive HIV-antibody, confirming ELISA positive test.
Thus for confirmation of HIV specific antibodies of the blood; ELISA test followed by Western blot is ideal
