Answer:
The mRNA strands go to the cytoplasm to meet ribosomes so protein synthesis can start.
Explanation:
In protein synthesis, the first step is to <em>synthesize messenger RNA</em>, mRNA. The coping process of the DNA section for the desired protein is called <u><em>transcription</em></u>, and it happens in the <em>nucleus</em>. After that, it occurs <em><u>translation</u></em>, when the formed <em>mRNA moves to the </em><em>cytoplasm</em> through the nucleus membrane pores. Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes are made of <em>protein and ribosomal RNA</em> and can be found in the r<em>ough endoplasmic reticulum</em> or floating in the <em>cytosol</em>. They read the mRNA code and add the correct amino acid using <em>transference RNA</em> to build the protein. mARN has a <em>start and end codon</em> that tells where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished. The new protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is <em>folding</em> to become functional. Finally, protein is transported by vesicles to the Golgi complex, and from there to its final destiny.
Answer:
Animal ; prokaryote ; plant ; virus
Explanation:
Animal: An animal cell possesses cell membrane, ribosomes, lysosomes and nuclear membrane.
Prokaryote: In a prokaryotic cell, cell wall is present such as bacteria, ribosomes are present but nuclear membrane is absent
Plant: A plant cell possesses cell wall, ribosomes, nucleus and a large vacuole.
Virus: Viruses reproduces inside a cell because they do not have their own energy producing system, nucleus is absent but nucleic acid ( DNA or RNA) is present
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. There are a few exceptions to this, such as ecosystems living around hydrothermal vents on the ocean floor, which derive their energy from the chemical compounds such as methane and hydrogen sulfide. In either case, the overall productivity of an ecosystem is controlled by the total energy available.
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Answer:
Rex is not a Tyrannosaurus rex because each of his hands has three fingers. Tyrannosaurus had only two fingers on each hand.
