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

    What is the typical gene structure?
    Each gene consists of
    1) a regulatory sequence (site where regulatory proteins can bind to). regulatory sequences can be found in a variety of locations
    2) a promoter - signals the beginning of transcription
    3) a transcibed region. contains the information that specifies an amino acid sequence
    4) a terminator - signals the end of transciption

    What is the genetic code?
    The genetic code is the set of rules by which information encoded in genetic material (DNA ormRNA sequences) is translated o proteins (amino acid sequences) by living cells. The code defines a mapping between tri-nucleotide sequences, called codons, and amino acids.

    Why is the genetic code said to be partially redundant?
    The genetic code is said to be redundant because some (but not all) of the amino acids have more than one possible codon coding for them.
