<span>Translation
</span>Remember that transcription happens in the nucleus as it changes from DNA
to mRNA. In translation,
the mRNA first has to leave the
nucleus and go into the cytoplasm of the cell.
The process of translation actually occurs in the cell’s ribosomes.
<span>
</span>The process of translation uses the genetic code on the mRNA strand to
direct the construction (making) of a protein molecule. <span>
</span>1. A ribosome attaches to an mRNA
molecule in the cytoplasm.<span>
</span>2. As each codon passes through the
ribosome, tRNA molecules bring the matching amino acids into the ribosome. Each tRNA has a set of 3 unpaired nitrogenous
bases called an anticodon which matches up with the codon coming through the
ribosome. So one end of a tRNA has an
anticodon and the other end carries the amino acid which is how the code is
translated.<span>
</span>3. The ribosome and the rRNA
molecules it contains attach the amino acids together as they are being
translated. The protein chain will keep
growing until the ribosome reaches the stop codon on the mRNA. At that point, translation is done and the
ribosome lets go.
Hope this helps!!!
1 is moving or kinetic energy of course because it is energy in motion.
Answer:
<em>Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out</em>
Answer:
What best describes how transferrin is transported through the erythrocyte plasma membrane is receptor-mediated endocytosis.
Explanation:
The incorporation of transferrin across the erythrocyte membrane depends on a transferrin receptor expressed on the surface of the membrane. The specific receptor recognizes the presence of iron-charged transferrin, transferin diferrica, incorporating it into the cell by endocytosis. Once in the cytoplasm, the iron is dissociated from the transferrin.
Free transferrin is called apotransferrin. The transferrin receptor has a high affinity for transferrin di-ferrica, which facilitates its incorporation by endocytosis, and the release of apotransferrin into the extracellular space.
The other options are not correct because:
<em> A. </em><u><em>Exocytosis</em></u><em> implies the exit of substances from the cell.</em>
<em> B. </em><u><em>Pinocytosis</em></u><em> involves the invagination of the membrane to incorporate soluble substances into the cell.</em>
<em> C. </em><u><em>Phagocytosis</em></u><em> is the incorporation of solid substances by invagination of the membrane.</em>
