Operons afford the organism the opportunity to
simultaneously regulate transcription of multiple genes, whose products are
active in the same process. Operons lead to the synthesis of groups of functionally
related enzymes, usually from a single mRNA transcript hence makes regulation of
the genes highly efficient.
Answer:
The theory of endosymbiosis has an intriguing logical history. German naturalist Robert Lauterborn found plant cells inside the single adaptable cell. It had two huge, frankfurter formed plastids named chromatophores, which helps in photosynthesis. He proposed this speaks to the beneficial interaction of two cells, this revelation helped in the advancement of endosymbiosis.
The Earth is green on the grounds that photosynthetic plants and green growth contain chlorophyll, a green color that reflects green frequencies of light. About 1.5 billion years back, an algal predecessor (single adaptable cell) immersed a photosynthetic bacterium, lessening it to a chloroplast, a plastid with chlorophyll. What's more, utilize its hereditary data to make own nourishment and it additionally offered ascend to the advantageous interaction (heterotrophic creatures) that relied upon the plants for the nourishment. One-celled critter inundated the bacterium, kept that cell alive and outfit its qualities for photosynthesis.
Answer:
There is no diagram but the cell division happens in stages. PMAT is a way to remember them. prophase, metaphase, anaphase, and telophase. This all takes place in Mitosis. Mitosis is the division of cells to make more *identical* cells, (skin cells, stomach cells). But Miosis is the making and division of sperm cells *not Identical* (sperm, and egg cells) are made in this phase.
