Question

The position of a gene located within a light G band on the long arm of chromosome 5 could be at which specific position?

a)5p13-pter.

b)513-qter.

c)5q13-qter.

d)p513.

e)q513.

Answer 1

Option is correct.

We represent positions of genes by numbers or letters.

First digit represents the number of chromosome so it will start from 5.

Second digit represents arm of chromosome , here it is long arm which is represented by q. So it is 5q till now.

Third digit represents the position of gene ...from options we can see that it can be 13 . And we don't know the exact location so we can use the range . ter means terminal position .

So the location is 5q13- qter.
