Select the statements that accurately describe different ways that translocations could lead to cancer.
a. a new sequence is added to a proto‑oncogene. the modified gene now produces a new protein that increases the rate of cell division.
b. a gene for a protein that is involved in a mitotic checkpoint is placed next to the regulatory sequence of a different gene. the gene is now expressed at inappropriate times.
c. a translocation disrupts a gene that encodes a protein required to pass through mitotic checkpoints. the resulting protein cannot function normally.
d. a gene for a protein that stimulates apoptosis is placed next to a regulatory sequence that increases the expression of the gene.
e. a translocation disrupts the sequence of a gene for a protein that stimulates apoptosis. the resulting protein cannot function properly.

The ways translocation can lead to cancer are;

1. A gene for a protein that is involved in a mitotic checkpoints is placed next to regulatory sequence of a different gene. The gene is noe expressed at in appropriate times.

2. Translocation disrupts the sequence of a gene for a protein that stimulates apoptosis .The resulting protein cannot function properly.

3. A new sequence is added to proto-oncogene. The modified gene now produce a new protein that increases the rate of cell division.

Explanation:

Chromosomal translocation is a process chromosomal abnormality where by a chromosome breaks, interchange and fuse to another chromosome entirely. It is the abnormal rearrangement of chromosomes. Chromosomal translocation that leads to cancer results from oncogene activation by a new enhancer and formation of oncogene fusion protein.

answer: blah

explanation:

bc blah

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
