How do transposable elements and short tandem repeats (STRs) differ? a. STRs occur within exons; transposable elements occur wit
Allisa [31]

Transposable elements and short tandem repeats are different because short tandem repeats make up only a small percentage of a given genome while transposable elements often make up larger parts of a genome. So the correct option is C.

<h3>What are transposable elements? </h3>

Transposable elements or transposons are a class of genetic elements. They can  “jump” from one location to another, in a genome.

Even though they are called “jumping genes,” they have an integrated site in a genome and are maintained there. Also, most of them are eventually inactivated and can not move any longer.

Whereas Short tandem repeats or STRs are short repeats of DNA. They are also known as microsatellites or simple sequence repeats. They have a repetitive unit of 1-6 bp and form a series of 100 nucleotide lengths.

Therefore the correct option C.

What is one reason why the classification of protists in one kingdom is difficult?
Aleksandr-060686 [28]

B.  Protists more closely resemble members of other eukaryotic kingdoms than they do other protists.

Explanation:

It is difficult for scientists to classify protists into one kingdom because they closely resemble member of other eukaryotic kingdoms than they do other protists.

The protists have a wide variations among themselves that makes them very difficult to classify.

  • Protists have a wide-range of diversity within them and they flaunt every rule used to classify them.
  • Protists have also shown characteristics of different kingdoms between them.
