Answer:
Amino acids.
Explanation:
DNA is the genetic material of all the organisms except some viruses. DNA has the ability to replicate and produce daughter DNA cells by the process of replication.
DNA is made of polymers of nucleotides. DNA consists of nitrogenous base, in which adenine is linked with thymine, cytosine with guanine thriugh hydrogen bonding ,shows complementary base pairing. Pentose deoxyribose sugar and phosphate group. The DNA molecules are linked together through phosphodiester bonds. Amino acids is present in protein.
Thus, the answer is option (4).

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.
