Structure. Cellulose<span> is a very important polysaccharide because it is the most abundant organic compound on earth. </span>Cellulose<span> is a major component of tough cell walls that surround plant cells, and is what makes plant stems, leaves, and branches so strong.</span>
Plant A, Plant B are the experimental subjects
Plant C is the control subject
The controlled variables are Temperature, Humidity and Water
Explanation:
As mentioned in the question the whole procedure is an experimental set-up where experiments are being done to test the growing condition of plants under a controlled environment. The various parameters such as Temperature, Humidity, Water, Light and colour of light are fixed. Following these controlled conditions different plants exhibit different growth after a period of three weeks.
3). The Plants which are experimental subjects are Plant A, plant B, Plant C
4).Plant C is the control subject since it is kept in the ordinary light conditons (i.e. white light)
5). The Controlled variables include Temperature, Humidity and Water content.
Answer:
Explanation:
The Escherichia coli catabolite gene activator protein (CAP) is a DNA binding protein involved with the transcription of several genes, including those that code for enzymes involved in the metabolism of certain sugars (i.e. lactose, maltose, and arabinose.) <u>Basically, CAP is responsible for the global regulation of carbon utilization.</u> Upon binding cAMP, CAP binds to a conserved DNA sequence from which it can either activate or repress transcription initiation from various promoters. In some cases clusters of several promoters are all controlled by a single cAMP-CAP complex bound to the DNA.
Once CAP has bound cAMP, the protein exhibits a higher affinity for a specific conserved DNA sequence. When the intracellular level of cAMP increases, the second messenger is bound by CAP and the cAMP-CAP complex binds to the DNA. Once bound, it is able to stimulate the transcription of the aforementioned genes. DNA bound by the CAP-cAMP complex is bent by ~90 degrees. This DNA bend, coupled with a protein-protein interaction between CAP and RNA polymerase is thought to be the mechanism by which CAP regluates transcription initiation on the chromosome.
No it is not possible since there can be dominated or recessive alleles involved. A heterozygous for a specific gene can display the same phenotype as a homozygous for the same gene.
