Transport protein cytoskeleton microtubule
Answer: All of the above.
Explanation: Inflammation process is part of the immune response to fight against infection or injury. It works together with the complement system that promotes the ability of antibodies and phagocytes to remove microorganisms and damaged cells from site of infection. Cytokines are produced by T-helper cells and macrophages to regulate inflammation by producing cytokines that sends positive feedback for the initiation of inflammation process. Promoting the production of chemicals, proteins and enzymes for chemotaxis and diapedesis of phagocytes.
Basically during inflammation the site of infection or injury will change colour and turn red, it will swell and cause the production of pyrogens which will result in fever symptoms due to raise of body temperature.
Answer:
The correct answer will be option-about 174 base pairs of DNA are wrapped around an octamer of histone proteins.
Explanation:
A nucleosome is the fundamental unit of the chromatin thread polymer of DNA which is made up of a nucleosome core. The nucleosome core is composed of histone proteins H2A, H2B, H3, and H4 arranged in two copies forming an "octamer structure of proteins".
About 174 bp of DNA wraps around this nucleosome which is connected to other nucleosomes through 160 to 240 bp linker DNA.
Thus, the selected option is the correct answer.
Answer:
The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds
Explanation:
The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.
Answer:The Ring of Fire is a ring of volcanoes around the Pacific Ocean that result from subduction of oceanic plates beneath lighter continental plates. ... This magma rises up through the over-lying plate to erupt at the surface. If the overlying plate is a continent, you get a chain of volcanoes such as the Andes or Cascades.
