Chromosomes similar in size, shape, genes and gene sequences are

Chromosomes as well as genes occurs in pairs.

Given below is a sequence of alphabets representing the genes of chromosome. Observe it and answer the questions. A - B - C - D - E - F - G - H - I - J - K . (a) Write the sequence of genes after the chromosome undergoes terminal deletion of single gene. (b) What will be the gene sequence, if the genes E and F undergoes tandem duplication ? (c) Consider the centromere is located between the genes F and G and write a gene sequence , after parametric inversion occurs in between the genes C, D and E.

In split genes coding sequences are ____________

A: HGP was completed in 2003 by sequencing all genes of all chromosomes. R: All conding and noncoding genes were sequenced by ESTs.

A: HGP was completed in 2003 by sequencing all genes of all chromosomes. R: All conding and noncoding genes were sequenced by ESTs.

Assertion : Chromosome 1 has 231 genes and the Y has 2968 genes. Reason : Repetitive sequences of DNA are through to have direct coding function and shed light on chromosome structure, dynamics and evolution.
