The answer is Retroviruses integrate DNA randomly in the
genome. While retroviruses integrate their
DNA permanently in their host genome, hence
a good tool for gene therapy, its risk of inserting
DNA at an unintended
location on target genome can cause insertional
mutagenesis. This mutation can cause activation of oncogenes hence lead to tumor
growth.
Answer:
Metaphase (mitosis) and metaphase I ( Meiosis)
Explanation:
In a diploid organism, the chromosomes are present in pair called homologous pair which has to be distributed in the cells during the cell division cycle.
The distribution of the chromosomes in a cell is observed in four subphases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes when are found in a condensed form and are present in the centre of the cell or at the equatorial plate is known as the metaphase.
In case of mitosis since the division takes place in one cycle, therefore, metaphase is the phase whereas in meiosis since the division takes place in two-cycle, therefore, metaphase I is correct as during the metaphase II the chromatids are present at the centre.
In a human? Need more context here but should be outside the cell. At equilibrium you will have a more negative environment in the cell.
Explanation:
chemo synthesis is a process by which certain microbes create energy by mediating chemical reactions
