Specific proteins produced in a cell are directly related to the nucleotide sequence in the DNA of a cell.
Answer:
German biologist Theodor Schwann concluded that Cinimals are made of cells. Rudolph Virchow concluded that new cells are produced from other cells 6. The Cele theory combines the conclusions made by Schleiden, Schwann, and Virchow.
Explanation:
SnRNPs bind to the primary transcripts and form the spliceosome which removes introns that mature mRNA
Blood flow through most organs in the systemic circuit is regulated primarily by increasing or decreasing the sympathetic activity to arterioral smooth muscles in the organ. Another form of regulation called active hyperemia, depends upon the ,metabolic activity of the organ. Increased activity leads to increased interstitial fluid metabolites, which cause dilation of the arterioles, the former is a type of extrinsic regulation of blood flow; the latter is an example of intrinsic regulation.
Answer:
The correct answer will be option- D.
Explanation:
Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.
The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.
Thus, option- D is the correct answer.
