Answer:
DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person
Explanation:
In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.
Mitosis goes in the blank
Answer: The DNA double helix is held together by two types of bonds,
covalent and hydrogen.
Explanation: Covalent bonds occur within each linear strand and strongly
bonds the bases, sugar and phosphate groups.
Answer AND Explanation:
The variations that Darwin regarded as raw materials for the process of evolution have been traced to changes that occur at the gene level or the chromosome and these changes are called mutations. Organisms with beneficial mutations are able to pass them on to their offspring during reproduction. Transmission of such mutations through many generations could lead to the emergence of new species. The emergence of new species requires a long time and is also affected by the rate of mutations that a particular species undergoes. This leads to evolution.
Low molecular weight heparin is associated with less thrombocytopenia than the normal heparin. Low molecular heparin also prevent unnecessary bleeding since it is not as strong as the normal heparin. Low molecular weight heparin are derived from smaller polysaccharide chain and their effect is more predictable than the normally unfractionated heparin. It also help treat deep venous thrombosis, which is commonly associated with prolonged sitting and standing. It is also used to treat pulmonary embolism especially the more massive one. However, care must be observe in using it since some patients elicit allergic responses to it.
