Answer:
I would expect to see 3 bands after completing DNA gel electriphoresis and staining the gel.
Explanation:
The restriction enzyme Hind3 has two Recognization sites in the 400 base pair long DNA molecule.
As a result the restriction enzyme Hind3 with generate 2 cuts in the target 400 base pair long DNA molecule.
The number of 2 cuts in the target DNA molecule will generate 3 DNA fragments.From this point of view it can be stated that 3 bands will form after completing DNA electrophoresis and staining the gel.
Answer:
nourish the placenta
Explanation:
The hormone called human placental lactogen (hPL) is a hormone secreted by the placenta, which functions to supply nutrients and oxygen to the growing fetus in the womb.
The human placental lactogen is produced to help in the efficient use of ingested food substances in the production of energy (metabolism). This indirectly helps to nourish the placenta because if the mother efficiently converts food into nutrients, the placenta is also adequately nourished.
Answer:
Option C
Explanation:
All of the following options are correct except option C. in the Meselson Stahl experiment, after the first round of replication, the DNA molecules made consisted mainly of one parental strand and one new strand each which is the DNA molecules of intermediate density (H-L). Then future replications will produce more of the low density L-L density. This form of replication is thus termed to be the semi conservative form of replication
Answer:
true
Explanation:
genetics is the study of heredity in organisms and heredity is the process of passing traits from parents to offsprings
