Transposable elements are DNA sequences that contain numerous point mutations. Thus, option "4" is correct.
<h3>What are Transposable elements?</h3>
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighbouring pieces of DNA, mobile elements move from one place to another causing many changes or mutations.
When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.
On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match.
This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.
Thus, option "4" is correct.

Although they flow near the bottom of the ocean, deep currents sometimes flow on top of other currents. while surface currents flow near the top of the ocean where they can reach depths of several meters. Some of the factors that control deep currents are salinity, density, and temperature. Deep current they occur deep in oceans which are influenced by salinity, temperature, and water.
A good example of deep current is Antarctic bottom water.
