Your Ad Here	Okazaki fragment A small, discontinuous strand of DNA produced by DNA synthesis. 2. The short pieces of replicated DNA along the lagging strand that are later rejoined by DNA ligase. Oligo Oligonucleotide Oligogenic A phenotypic trait produced by two or more genes working together.
Oligonucleotide A molecule usually composed of 25 or fewer nucleotides; used as a DNA synthesis primer. 2. A short sequence of single stranded DNA or RNA. It is often used as a probe for detecting complementary DNA or RNA. 3. A deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) sequence composed of two or more covalently linked nucleotides. Oligonucleotides are classified as deoxyribooligonucleotides or ribooligonucleotides. Fragments containing up to 50 nucleotides are generally termed oligonucleotides, and longer fragments are called polynucleotides.
Omphalocele A protrusion of a part of the intestine through a large opening the site of the abdominal wall at the site of the umbilicus. The protruding bowel is covered by a thin transparent membrane and 30 % of infants with an omphalocele are felt to have a chromosomal defect. Oncogene Agene, one or more forms of which is associated with cancer Many oncogenes are involved, directly or indirectly, in controlling the rate of cell growth 2. A gene capable of transforming normal cells into cancer cells. Oocyte A cell that undergoes two meiotic divisions to produce an ovum (egg). An oocyte prior to completion of meiosis I is a primary oocyte; and oocyte prior to completion of meiosis II is a secondary oocyte.	Your Ad Here
A nucleotide is composed of a purine or pyrimidine base, a 5-carbon sugar, and a phosphate group. A deoxyribooligonuc1eotide consists of a 5- carbon sugar called deoxyribose joined covalently to phosphate at the 5 and 3 carbons of this sugar to form an alternating, unbranched polymer (see illus.). Fig. The Backbone Structure of Oligonucletides as the Sodium Salt actual oligonucleotides are 20-50 bases in length. Bases may be thymine Uracil, Cytosine, Guanine or Adenine. The Backbone Structure of Oligonucletides A purine or pyrimidine base through one of its nitrogens by an N-glycosidic bond to the 1 carbon of deoxyribose. The four bases found in a deoxyribooligonuc1eotide are guanine, cytosine, adenine, and Fig. The backbone structure of oligonucleotides as the sodium salt; actual oligonucleotides are 20-50 bases in length. Bases may be thymine, uracil, cytosine, guanine, or adenine.
Your Ad Here	A ribooligonucleotide consists of a similar repeating structure where the 5-carbon sugar is ribose. The four bases found in a ribooligonucleotide are guanine, cytosine, adenine, and uracil. The sequence or ordering of these bases determines the biological function of the deoxyribooligonucleotide or ribooligonucleotide Oogenesis The process of formation of an egg or ovum.

Open reading frame (ORF)
The sequence of DNA or RNA located between the start -code sequence(initiation codon) and the stop-code sequence (termination codon)
2. The sequence of nucleotides between a start (initiation) codon and an in-frame stop(termination) codon that codes for amino acides to be incorporated into a polypeptide.

Operator
A region of DNA in a prokaryotic operon that interacts with a repressor proteinto control the transcription of an adjacent gene or gene set.

2. A chromosomal region capable of interacting with a specific repressor, controlling the functioning of adjacent cistrons.
