Different forms of a given gene are known as "alleles". Alleles are essential for the formation of life and add to diversity both within and outside the organism itself in many ways.
Answer:
The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.
Explanation:
Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.
An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
Cell division has two checkpoints namely, G1 checkpoint and spindle assembly checkpoint. The checkpoint which determines if division has properly occurred is the G1 checkpoint. At this point, is a damage in the DNA is detected or the has not reach the optimum size, the cell is stopped in G1 and is not allowed to proceed to further process.
The correct answer is 5′ to 5′ triphosphate linkage.
<span>mRNA capping is the posttrancriptional modification of messenger RNA when the nucleotide on the 5′ end is specially altered. The process is highly regulated and it creates stable and mature messenger RNA able to undergo translation. The cap on the <span>5’ end of mRNA consists of a guanine nucleotide connected to mRNA via an unusual 5′ to 5′ triphosphate linkage. Guanosine is methylated on the position 7 after capping.</span></span>
