Inference
A conclusion drawn from evidence.

Informatics
Storing, manipulating, analyzing and visualizing information using computer systems.

Informed consent
An individual willingly aggress to participate in an activity after first being advised of the risks and the benefits.

Inherit
In genetics, to receive genetic material from parents through biological processes.

Inheritance
Transmission of genes from parent to offspring.

Inheritance of acquired characters.
Historically influential but factually erroneous theory that an individual inherits characters that its parents acquired during their lifetimes.

Inherited
See: Inherit

Initiation codon
The triplet nucleotide code, AUG, in an mRNA that signals the start of translation and codes for the insertion of methionine as the first amino acid in a polypeptide.

Initiation factor.
Any of a group of proteins required for the initiation of translation.
2. A protein required for the initiation of protein synthesis.

Insectivorous
Feeding largely or exclusively on insects

Insertion
A chromosome abnormality in which a piece of DNA is incorporated into a gene and thereby disrupts the gene’s normal function. See also: chromosome, DNA, gene, mutation 2. The intertion of a segment from one chromosome into another chromosome.

Insertional mutation
See: insertion

Intellectual property rights
Patents, copyrights, and trademarks. See also: patent.

Intelligent design
The non-scientific argument that complex biological structures have been designed by an unidentified supernatural or extraterrestrial intelligence. Intercalating agent
A compound that inserts between adjacent base pairs in a DNA molecule, disrupting base pairing in complementary strands.

Interference
One crossover event inhibits the chances of another crossover event. Also known as positive interference. Negative interference increase the chance of a second crossover.

Interphase
The period in the cell cycle when DNA is replicated in the nucleus; followed by mitosis.
2. The stage of the cell cycle between cell divisions. It is during interphase that DNA replication and gene expression occur.

Intron

DNA sequence that interrupts the protein-coding sequence of  a gene; an intron is transcribed into RNA  but is cut out of the message before it is translated into protein.
2. Noncoding DNA sequences that interrupt the sequences containing instructions for making a protein(exons). Introns are not represented in messenger RNA; only the exons are translated into protein. The function of introns is still being explored.
3. A Portion of DNA found between exons. Introns are transcribed, but are not present in the final processed transcript.
4. The nucleotide sequences of some genes consist of parts that code for amino acids, and other parts that do not code for amino acids interspersed among them. The interspersed non coding parts, which are not translated , are called introns; the coding parts are called exons.
5. In split genes, a segment that is transcribed into nuclear RNA, but is subsequently removed from within the transcript and rapidly degraded.
6. The DNA base sequences interrupting the protein-coding sequences of a gene in genomic DNA; these sequences are transcribed into RNA but are cut out (spliced out) of the messenger RNA (mRNA) before it is translated into a protein molecule.
