GENE EXPRESSION

Question:

1) What are the basic steps in translation?. In what part of the cell does this occur?

Answer:

During translation the genetic code is used to make a polypeptide chain with a specific amino acid sequence.

1) the messenger RNA goes to the cytoplasm where it is attached to a cellular structure called a ribosome. Ribosomes are two part molecular assemblies consisting of various proteins plus a special kind of RNA called ribosomal RNA. Ribosomal RNA is involved in catalyzing some of the chemical reactions of translation.
2) another kind of RNA called tRNA carries amino acids to the mRNA when it is attached to a particular part of the ribosome's small subunit, called a binding site. A critical feature of mRNA and how it is translated is the fact that each three nucleotides in the mRNA is called a codon and it is the codon that is translated.

translation takes place in the cytoplasm
