the relationship between DNA, codons, amino acids, and proteins. During transcription, DNA is transcribed into messenger RNA when the the base codes in DNA are copied. mRNA serves as the code for assembling amino acids in a certain order.
In contrast to compact bone, spongy bones does not contain true Haversian systems( tiny tubes that form a network in bone and contain blood vessels) but consist of an irregular lattice of thin plates of bone called trabeculae.
The spaces between trabeculae are filled with marrow. The cells of the red marrow are responsible for producing blood. Within trabeculae lie lacunae which contain osteocytes.
Blood vessels from the periosteum penetrate through to the spongy bone, and osteocytes in the trabeculae are nourished directly from the blood circulating through the marrow cavities.

<em>Several scientists make the same observations about the effect of sunlight on algae. This set of observation is called Working theory. ... The study of algae is called phycology or algology. The term shields a variety of photosynthetic creatures, and many are not narrowly related.</em>
