When DNA provides instructions to make a protein?

Answer 1

DNA must first undergo the last 2 parts of the "Central Dogma" of Biology. It must first complete the process of transcription, where the coding strand of DNA makes the mRNA into codons. The anticoding strand of DNA makes tRNA into the anticodons. This takes place inside the nucleus of the cell, as DNA is too big to fit through the cell's nuclear pores. The mRNA travels out into the cytoplasm until it reaches the ribosome, where it and the tRNA can complete the process of translation. This is when the amino acid chain is grown until a stop codon is reached. Once the stop codon is reached, the chaperone enzyme comes along to bend and fold the amino acid chain into the special 3D shape of the protein.

Answer 2

The chromosome(s) made of DNA:

1. in prokaryotes (e.g. bacteria) there is one large circular chromosome and several smaller circular plasmids that float free in the cytoplasm that contain the necessary genetic information
2. in eukaryotes there are several linear chromosomes contained in the nucleus (as well as circular chromosomes in other organelles, e.g. mitochondria) that contain the necessary genetic information.

Answer 3

The process of gene expression involves transcribing DNA into messenger RNA (mRNA) in the nucleus. The mRNA is then translated into a sequence of amino acids, which ultimately forms a protein. This process occurs in the ribosomes within the cytoplasm of the cell.
