The basic units that are put together over and over to build a strand of dna are called as nucleotides.
<u>Explanation:</u>
DNA is a heteropolymer that involves many monomers that is the nucleotides that are joined together by phosphodiester bonds in order to develop a complete DNA. The nucleotides consists of nitrogenous bases, phosphate groups and the sugar molecules that are bound together to form a complete nucleotide. The phosphate groups form a backbone through which the nucleotides are joined together.
When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, although he did not know it at the time.

The correct answer is the mesophyll tissue from a leaf.
The mesophyll is the term given to the two cell layers present within the leaves of a plant. The first layer is situated within the epidermis but above the second layer. The second layer is the palisade parenchyma cells.
The palisade layer is loaded with ample of chloroplasts, making it the layer most directly accountable for photosynthesis. These chloroplasts absorb the maximum part of the light energy utilized by the leaf.
