1. 16S rRNA
A large polynucleotide (about 1500 bases) which functions as a part of the small subunit of the ribosome of prokaryote s and from whose sequence evolutionary information can be obtained; the eukaryotic counterpart is 18S rRNA.

2. 3' end
The end of a nucleic acid that doesn't have a nucleotide bound to its 3' of the terminal residue .

3. 5' end
The end of a nucleic acid sequence where the 5' position of the terminal residue isn't bound by a nucleotide .

4. 5-fluorouracil (5-FU)
An anti- cancer agent similar in structure to the nitrogenous base thymine , which inhibits the enzyme dihydrofolate reductase (DHFR) and thus nucleotide synthesis, so that it is particularly harmful to rapidly growing cells such as in tumors .

5. 5-hydroxymethylcytosine
A nucleotide base derived from cytosine which is used by the bacteriophage T4 in place of cytosine in its DNA . The substitution protects the bacteriophage from its own nuclease enzyme s (enzymes which cut apart DNA).

6. 7-methyl guanosine
A guanosine ribonucleotide (has the nitrogenous base guanine attached to the sugar ribose ) which has a methyl group attached to the 7th ring atom of the guanine (a nitrogen atom). These are found at the capped 5'-ends of eukaryotic mRNA .

7. Adaptors
Short synthetic oligonucleotide strands that have one sticky end and one blunt end; the blunt ends join to the blunt end of a DNA fragment, forming a new fragment with two sticky ends that can be more easily spliced into a vector .

8. Adenine
One of the four nitrogen-containing bases occurring in nucleotides , the building blocks of the organic macromolecule group known as nucleic acids (DNA and RNA). Adenine is also the base in the energy carrying molecule ATP (adenosine triphosphate) which is the energy coin of the cell.

9. Adenosine triphosphate (ATP)
A common form in which energy is stored in living systems; consists of a nucleotide (with ribose sugar) with three phosphate groups. The energy coin of the cell.

10. Agarose gel electrophoresis
A type of electrophoresis that uses a matrix of highly purified agar to separate large DNA and RNA molecules (generally around 20,000 nucleotide s in size).
