Answer:
Option A , Genome
Explanation:
Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.
Hence, option A is correct
<span>These organisms obtain energy and carbon from the physical environment and use it to produce their food. They make sugars and other compounds using sunlight as a source of energy and carbon dioxide as a carbon source. The evolutionary advantages for these organisms are the periodic renewal of atmospheric O2 for all living beings. The production of organic matter and food webs of any ecosystem. Without them, there is an extinction of all living organisms due to the non-renewal of atmospheric O2 and the excessive accumulation of CO2 in the atmosphere.</span>
Answer/Explanation:
Using solar energy, photosynthesis uses carbon dioxide and water to produce glucose and oxygen, whereas respiration uses glucose and oxygen to produce energy, releasing carbon dioxide and water.
Therefore, photosynthesis and respiration act as a cycle, using reverse reactants and products.
Photosynthesis builds food for the cell to use, respiration uses this food to power cellular processes.
