Protein Translation
... In any mRNA sequence, there are three ways triplet codons can be read. Each way to read the codons is called a "Reading Frame". It is very important for ribosome to find correct reading frame. If the wrong reading frame is used, translation generates a protein with the wrong amino acid sequence ...

New strands of DNA are built from the template strand, using DNA polymerase (enzyme) to bring in the nucleotides. Nucleotides on the leading strands are brought to the template strand in a continuous fashion. Nucl ...

Restriction Enzymes
... Restriction enzymes are part of a bacteria's ''immune'' system. These are enzymes that cut DNA at specific sites (typically a four or a 6 base-pair sequence). Bacterial DNA is modified to be protected by methylation while foreign DNA, such as incoming viruses, are not. Usually, organisms that make ...
