Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
Hai there :3 I'm planning to study chemical engineering.
Question related to Biochemistry (Photosynthesis & Cellular Respiration)
1. Chemiosmosis. In the process of chemiosmosis, specific enzymes (such as ATP synthase) create ATP. Hydrogen ions go from a higher proton concentration to a lower one, which is why it's called chemio"osmosis"
2. Electron Transport Chain (ETC). The name says it all. Simply explained, electrons are transported and transferred in the mitochondrial membrane.
3. Oxygen. O2, the diatomic molecule, is essential in respiration. In the final stage of respiration, at the near end of the electron transport chain, oxygen accepts protons to become water. Cells use O2 during oxidative phosphorylation.
4. NADPH. I remember learning what this acronym means by heart. Nicotinamide Adenine Dinucleotide Phosphate Hydrogen. NADPH is essential in photosynthesis as a typical coenzyme in the reduction of chemical reactions.
Answer:
Explanation:
pollen grain sticks to the stigma, where the pollen build up a pollen tube to the ovule, after fertilization the ovary then builds up to develop into a fruit, depending of the the type of flower the fruit can be determined
Answer: Option C
Explanation:
These cells are soft because of its function. Gaseous exchange takes place by the help of these cells. Spongy mesophyll cells are covered by thin layer of water and are loosely packed.
This is because, during the day time when the plant is performing photosynthesis these cells allows the carbon dioxide into the mesophyll cells and the oxygen out of the plant body.
When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.
