Answer:
The correct answer will be option- the sticky ends are more efficient than blunt ends.
Explanation:
The molecular cloning is the commonly used technology which uses restriction enzymes to make cuts in the DNA. Depending on the activity of these enzymes, they produce two types of ends: sticky ends and blunt ends.
The sticky ends produce unpaired nucleotide overhangs whereas blunt end produces paired nucleotide. The advantage of the overhangs is that they find complementary overhangs to bind as quickly as possible and require less amount of DNA ligase to join nucleotide. This ensures that the sticky ends DNA binds in the right direction.
Thus, the sticky ends are more efficient than blunt ends.
Explanation:
The phase of Prophase I of meiosis is very long and divided into 5 subphases: Leptotene, Zygote, Pachytene, Diplotene, and Diakinesis. During a phase of the Diplotene, the degree of condensation is high, which allows individualizing the sister- chromatids that remain attached by the cohesins. The synaptonemal complex disintegrates, and from the centromeres begins a repulsion between homologous chromosomes, which remain associated only with the places where they occur as permutations.
These sites are called chiasmas (Greek, crossed) because they show the crossover of homologous chromatids. Chiasmas represent the cytological finding of the occurrence of permutation. The presence of at least one bivalent chiasm is essential to ensure the correct segregation of the homologous chromosomes in anaphase I.
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.

Community one because there are more different types of species and less of them.
Hey there! So, another power house for plant cells maybe the chloroplast! Another idea could also be Vacuoles, and even ribosomes!
Hope I helped! Good luck!
