What of the following is a major difference between site-specific recombination and transposition?
a. transposition is much more carefully controlled than site-specific recombination.
b. site-specific recombination involves two defined sequence elements, whereas transposition involves the movement of a specific sequence to a nonspecific site in the dna.
c. transposition involves two defined sequence elements, whereas site-specific transposition involves the movement of a specific sequence to a nonspecific site in the dna.
d. site-specific recombination is much more carefully controlled than transposition.

The correct answer is option B. "Site-specific recombination involves two defined sequence elements, whereas transposition involves the movement of a specific sequence to a nonspecific site in the DNA".

Explanation:

Site-specific recombination is a type of genetic recombination that involves two defined sequence elements. The recombination is catalyzed by Site-specific recombinases (SSRs) that recognizes and binds to the short DNA sequences that are recognized. On the other hand, transposition is a type of genetic recombination that involves the movement of a specific sequence to a nonspecific site in the DNA. Transposition is mediated by transposases, a large super-family of enzymes from both prokaryotes and eukaryotes.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
