eukaryote cells DNA is found in the nucleus of the cell, the form the
DNA (e.g. chromosomes vs. chromatin) is in depends on what stage of the
cell cycle you are talking about. In cells that have mitochondria, DNA
is found there as well. Mitochondrial DNA is distinct from nuclear DNA
and doesn't code for the same things. In prokaryotic cells DNA is found
in the cytoplasm. Don't forget that other entities may also contain DNA
such as viruses.
Although DNA is technically confined to the places outlined above, the
reality is cells are dying all the time and spilling their contents
including their DNA. As a result DNA is all over us and everything we
touch, and the same goes for other organisms.
Bacterial cells DON'T typically have a nucleus. They are called
prokaryotic because of that (prokaryotic means "before nucleus" where as
eukaryotic means "true nucleus"). Their DNA is typically in the
cytoplasm usually as a single circular shaped chromosome. The also
sometimes have smaller peices of circular DNA called plasmids that are
also in their cytoplasm which they can exchange with each other.. </span>
Answer:
Option (3).
Explanation:
Teratogens may be defined as the chemicals that can cause birth defects in the fetus. Substances like alcohol, lead and nicotine acts as the main agents of tertaogens.
Shamona is drinking water that contains high level of lead. The element lead is harmful for the fetus. Even the small concentration of lead is enough to cause birth defects. The lead exposure can cause the abnormal development of brain and damages the brain of fetus. The fetus has low birth weight also.
Thus, the correct answer is option (3).
The answer is Progestins. Some of numerous artificial progestational constituents that mimic some or all of the engagements of progesterone which is used as contraceptives one or the other single-handedly or in group with estrogen and with estrogen in hormone added therapy and in addition, it is female hormone like progesterone that turns on the inner lining of the uterus.
