Answer:
Why does dna rely on rna?
Transcription is carried out by the DNA-dependent RNA polymerase that replicates the series of the DNA chain into RNA. To start transcribing the sequence, the RNA polymerase binds to the series of DNA called the promoter and divides the DNA strands. It then copies the sequence series into the messenger RNA copy until it hits the part of DNA named the Terminator, where it halts and detaches from the DNA. As with being DNA-dependent DNA polymerases, RNA polymerase II, this protein that transcribes most of these factors at the human genome, controls as part of the huge protein structure with multiple regulatory and accessory subunits.
Why can’t dna deliver the instructions to the ribosomes directly
Transcription begins at the nucleus, which is the mind of the cell. It contains DNA which include all the messages we want to create proteins. These messages are taken by those ribosomes outside the nucleus. DNA is also valuable to be run in the cell, it wants to be there as a kind of professional material. Then this cell gets another copy of it in the process called transcription.
Choloesterol is present in the membrane. It's role in the membrane is permeability reduction. Cholesteron is also used in corticosteroids synthesis(hormone secreted by the renal glands)
Hormones are secreted and released into the blood by Endocrine glands.
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.
Animal cells each have a centrosome and lysosomes, whereas plant cells do not
Uv light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life
