Answer:
The function of biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.
Explanation:
a enzyme structure/catalysis Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.
b mRNA structure/protein synthesis mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.
c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.
Both fight over infection and work on the rebuild of body tissue
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
Answer:
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between variables. The correlation coefficient is usually represented by the letter r.
Explanation:
Answer:
The correct answer will be option-D
Explanation:
Apoptosis is the process which leads to the death of the cell which is programmed and thus is known as the programmed cell death.
The death of a cell takes place when the cell experiences the lack of survival signals either due to the need to kill the cell or some genetic defects in DNA contained in cells.
The cell which undergoes apoptosis process can be easily marked by their shape as it gets shrunk, the cytoskeleton of the cell collapses, irregular bulges called blebs and the disassembly of the nuclear envelope.
Since the cell shrinks instead of swelling, therefore, option-D is the correct answer
