In low nitrogen environments, heterocyst differentiation is triggered by the transcriptional regulator NtcA. NtcA influences heterocyst differentiation by signaling proteins involved in the process of heterocyst differentiation. For instance, NtcA controls the expression of several genes including HetR which is crucial for heterocyst ...
[4] [7] This is associated with the accumulation of nucleic acids which is important for both dormancy and germination of the akinete. [7] Despite being a resting cell, it is still capable of some metabolic activities such as photosynthesis , protein synthesis, and carbon fixation , albeit at significantly lower levels.
Auxospores are involved in re-establishing the normal size in diatoms, as successive mitotic cell divisions leads to a decrease in cell size. This occurs because each daughter cell produced by cell division inherits one of the two valves that make up the frustule (a silica cell wall), and then grows a smaller valve within it.
Phycobilisomes can be used in prompt fluorescence Archived 2018-03-18 at the Wayback Machine, [7] [8] flow cytometry, [9] Western blotting and protein microarrays. Some phycobilisomes have an absorption and emission profile similar to Cy5 , allowing them to be used in many of the same applications.

In a group of 490 children in California with elevated risk of autism spectrum disorder, the test was able to rule it out with about 92.5% accuracy, the company said. However, the results have not ...
Phenotypic screening is a type of screening used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell or an organism in a desired manner. [1]
Here are 7 of them, according to science. Number 7. Seeing colors. It comes down to the ability to perceive red, and that is an X-chromosome enabled skill. As women have 2 of them to men's 1, they ...
