BIOM20001 Lecture Notes - Lecture 17: Noncoding Dna, Nucleoid, Transposable Element
Document Summary
The total amount of genetic material in a chromosome set. A dna sequence coding for a protein (polypeptide) or a functional rna. Non-coding region (portion not translated) of an mrna molecule. A non-functional gene relic consisting of a short isolated region from within a gene. Dna sequences that resemble functional genes but are non- functional in that they no longer encode functional proteins or are otherwise no longer expressed in the cell. A dna segment that can move from one position in the genome to another (non- homologous) position. A repeated end-to-end duplication of a core dna sequence at a defined locus. Microsatellites an array of very short tandem repeats (2-6 base pairs each). The mass of genetic material composed of dna and proteins that condense to form chromosomes. A short length of dna (~147 bp) wrapped around an octameric core of four histone proteins (two copies each of histone h2a, h2b, h3, and h4).
