The members of the phylum arthropoda have jointed legs. the number of jointed legs are variable, may be three pairs as in cockroaches, four pairs in prawns and even hundred pairs in centipedes. Members of this phylum have ability to shed their their exoskeleton(molting) and body is divided into three fused segments - head, thorax and abdomen.
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
Answer:
- The former bacteria, Pseudomonas sp., has the ability to utilize benzoate as a source of carbon.
- Pseudomonas sp. can also migrate in the direction of areas with higher oxygen concentrations.
Whereas the latter, Bacillus sp., does not possess these characteristics.
Explanation:
The two traits mentioned above will provide the basis upon which the strategy for enrichment can be made.
Answer:
covalent bonds
Explanation:
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
