Transcription occurs in the nucleus of the cell. RNA polymerase breaks the hydrogen bonds and unzips a portion of DNA. RNA nucleotides match the DNA strand forming mRNA. In mRNA thymine is replaced by uracil. Once mRNA is formed it leaves the nucleus through a nuclear pore into the cytoplasm. The purpose of mRNA is to remove the protein code out of the nucleus without pulling the DNA out. mRNA then needs to find ribosomes in the cytoplasm which can be found on the rough ER. mRNA has read three bases at the same time and these are called codons. Ribosomes read the mRNA code and add the correct amino acid using tRNA. tRNA has an anti-codon on one end which will match a specific codon, and a specific amino acid on the other end. This will make translation happen.
Translation- mRNA attaches to a ribosome and a start codon must be read. tRNA brings the first amino acid which matches the codon on mRNA. The next tRNA molecule moves in and matches with the codon on mRNA while amino acids form a peptide bond. First tRNA detaches itself and mRNA shifts for the next tRNA molecule to come in. Protein grows until a stop codon is reached and then it's ready to finish folding to become functional.
Carbon since all life requires it
Grey seals breed in habitats where disturbance is kept to a minimal, like rocky shores, ice flows and islands. They feed on cold open waters. When pups are given birth in early winter or late autumn, their skins are white with yellowish tint. They are relatively helpless and rely on their mother's milk for the first few weeks after birth. They deposit a thick layer of blubber that will protect and allow them to adapt to the cold to sustain them when they will hunt for themselves. Hope this helps...
<span>The cell would not survive if it gets exposed to drug which disables the transport proteins in the cell membrane. Due to this the supply of nutrients is not received by the cell and the cell is not capable of producing the molecules that are needed for the growth.</span>
Answer:
The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere.
Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).
Explanation:
Both the cycles use plants as an integral component. Both the water cycle and carbon cycle use subsurface for long term storage. The water forms groundwater and can be stored for long duration. Similarly, carbon is stored in rocks for long term.
