define gene?
give importance of chromosomes?
Answers
Genes are the specific sequences of nucleotides present on chromosomes which encode particular proteins and express in the form of some particular feature of body.
Chromosomes are important because they carry the hereditary material (genes).
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. ... Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features. Scientists keep track of genes by giving them unique names.
To put it simply, chromosomes are important because they contain the entire (or at least the vast majority of) genetic information for an organism. The organism's DNA is contained within the chromosome as a long series of nucleotides that are organized into genes.
