Answer:
a. concentration gradient
Explanation:
i did it in apex and got it right.
Genetic information from DNA to RNA is called transcription which involves the enzyme RNA polymerase. The DNA is read from 3' to 5' in direction and produces an mRNA (messenger RNA) which contains the genetic data from the DNA. This mRNA strand is further processed in the nucleus (capping and adding a poly-A tail) before being transported to the cytoplasm.
The information contained in mRNA is used to make a polypeptide chain is called translation. This involves the use of ribosomes in the cytoplasm which attach themselves to the mRNA strand then using tRNA (transfer RNA) to add amino acids to the elongating polypeptide depending on the codon in the mRNA.
I believe that would be an open system.
Which of what following ?
Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
