The first stage is TRANSCRIPTION, it is a process that takes place in the nucleus or in the cytosol, the DNA acts as a template to transcript it's information forming a new mARN molecule which contains the codons that codes an specific amino acid.
This mARN molecule will exit the nucleus and will be translated in the ribosomas that can be found in the cytosol or the Endoplasmic Reticulum. during TRANSLATION the mARN will be decoded to produce a polypeptide chain, this happens when the ribosome induces the binding of a tRNA anticodon sequences that are complementary to the mRNA codons, this will tell the ribosome which amino acid is needed to form the polypeptide chain.
It's important to clarify that in Prokaryotic cells, both of these stages take place in the cytosol since it doesn't have organelles binded by membrane unlike the Eukaryotic cells where the Transcription happens in the nucleus and the translation happens in the cytosol or endoplasmic reticulum
Natural selection is a type of evolution that allows organisms to adapt into the environment they're in for survival.
Answer:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
Explanation:
So the flowchart should go like this:
Mutation in the CFTR gene >>>>>> Production of defective CFTR protein >>>>>> defective CFTR protein in cell membrane or no protein at all >>>>>>> Impaired ion transport across the cells >>>>>>> Cells secrete less chloride >>>>>>> leads to more re-absorption of sodium and water into the cells >>>>>>> decreased hydration of mucus present outside the cells as more water is absorbed into the cells >>>>>>>> thick viscous mucus.
