The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density
than humans. An example is bacteria with gene densities ranging between 100 –
500 genes/Mb. Gene density is therefore
not a good characteristic in determining
the complexity of an organism.
To preserve and keep them fresh
Meiosis produce variations in daughter cells whereas mitosis produce identical nuclei.
Hope this helps!
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.
Answer and Explanation:
When a cell is freezed, it cytoplasm-which is mostly water- is frozen and its volume expands. In consequence, pressure inside the cell increases and that causes damage to the outer wall.
The same occur in an unopened softdrink when it freezes. The volume inside the container increases and the pressure increases. If this volume increment is not considered before freezing the liquid, it could cause the container damage or breaking.
