Plants, humans, animals, and microorganisms is the answer to this question
The picture I have inserted from my notes should help with genes.
Alleles are two different forms of a gene.
<span>The upper AMDR limit for protein consumption is 35% of total energy intake. In other words, if you consume 2500 kcalories throughout the day, then at most 35 percent of those calories must come from proteins such as meats, beans, seafood, and eggs. We have that 35 percent of 2500 kcalories is 875, so the upper limit on how much protein this person should consume is 875 kcalories.</span>
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.
