If a piece of DNA breaks off of a chromosome and attaches itself?

Question

to a nonhomologous chromosome at another location what type of chnage has occurred?

A Translocation

B. Duplication

C. Deletion

D. Inversion

Answer 1

A. Translocation

Answer 2

Translocations
A translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome. This type of rearrangement is described as balanced if no genetic material is gained or lost in the cell. If there is a gain or loss of genetic material, the translocation is described as unbalanced.

Deletions
Deletions occur when a chromosome breaks and some genetic material is lost. Deletions can be large or small, and can occur anywhere along a chromosome.

Duplications
Duplications occur when part of a chromosome is copied (duplicated) too many times. This type of chromosomal change results in extra copies of genetic material from the duplicated segment.

Inversions
An inversion involves the breakage of a chromosome in two places; the resulting piece of DNA is reversed and re-inserted into the chromosome. Genetic material may or may not be lost as a result of the chromosome breaks. An inversion that involves the chromosome’s constriction point (centromere) is called a pericentric inversion. An inversion that occurs in the long (q) arm or short (p) arm and does not involve the centromere is called a paracentric inversion.

THE ANSWER IS TRANSLOCATION.

Answer 3

a. Translocation.

This could lead to, with subsequent divisions, to duplications or deletions. But the process itself is translocation.

Answer 4

The only plausible answer is translocation.

Answer 5

E. formation of a mutant, eg David Gest.

Answer 6

not sure but translocation..however wait to hear other answers too.

Answer 7

translocation
