DNA is made up of segments called  nucleotides

. Genes provide the coding to create  codon

. Proteins are created through the processes of  translation

and  transcription

. Together these processes are known as  protein synthesis

. The first step in protein synthesis is transcription, where translation

is used as the template for the creation of an mRNA strand. The enzyme,  RNA  Polymerase

matches up the correct bases, using  base-pairing

rules. When adenine is found on the DNA strand,  cytosine

will be the complementary base on the mRNA strand. When thymine is found on the DNA strand,  adenine

will be the complementary base on the mRNA strand.

and guanine are the other two bases that pair with one another. Since DNA is too large to leave the nucleus of the cell,  tRNA

must be created. It is smaller and able to travel outside the  nucleus

of a cell. Next, mRNA leaves the nucleus, heads through the  cytoplasm

towards a  ribosome

where translation occurs. In the ribosome, a  codon

on the mRNA strand (3 bases), connects to the anticodon on a  tRNA

molecule. When the codon and anticodon connect, the  amino acid

on the tRNA molecule detaches, forming a  polypeptide chain

which eventually makes up the protein. Proteins are essential for life because they make up the  structure

of living organisms and help organisms to function.

Explanation:

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
