The development of retinoblastoma is associated with a mutation in the 13q14.2 region of the human genome. What is the principle of indexing different parts of the genome?

Genome indexing is a strategy to find a pattern (i.e., a short sequence read) in a long text (i.e., the genome)

Explanation:

Genome indexing is a similar strategy used when a book is indexed. This strategy is used to find more rapidly a given sequence by allowing to align the problem sequence and thus approximate to the putative origin of the query sequence within the genome. Genome indexing enables to design PCR primers/probes, map probes at genome level, understand data obtained from gene expression analyses, etc.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
