The condition consisten with the protrusion of the membranous sac that encloses the abdominal contents through an opening in the abdominal wall into the umbilical cord is called Omphalocele
Answer:
c. Major groove
Explanation:
The interaction surfaces of proteins are, in general, varied. From the point of view of the secondary structure, the surfaces of the proteins are formed by the surfaces of their α helices, β sheets and loops that conform them. The surfaces of the DNA molecules are less varied: the B-DNA helix has a monotonous “screw” shaped surface with phosphoribose ridges between which two grooves (major and minor) are formed. The difference between different nucleotide sequences can only be seen from outside in the major groove, where the bases appear. The surfaces of RNA molecules that possess tertiary structure (such as t-RNA) are almost as complex as that of proteins.
Since the major groove is the only site where the bases are accessible from outside the B-DNA without distorting it, the major groove constitutes the main recognition site. As the interaction between molecules is stronger if their surfaces are complementary, the protein-DNA interaction usually occurs by filling the major groove.
Answer:
Explanation:
Only archaebacteria are capable of methanogenesis
Archaebacteria who use other forms of cellular respiration also exist, but methane-producing cells are not found in Bacteria or Eukarya.
Unique cell membrane chemistry. Archaebacteria have cell membranes made of ether-linked phospholipids,
Macromolecules contain large number of atoms. Milk contains
both carbohydrates and proteins, because it gave a positive result upon the
addition of Benedict’s solution which indicated an orange color. It means that
there is a concentration of reducing sugars in milk.
Answer:
The correct answer is They are very common in symbiosis in all plant families.
Explanation:
Nitrigen fixation is a process in which the atmospheric nitrogen is converted to ammonia by the help of nitrogen fixing bacteria such as azobacter, clostridium.
These bacteria lives in the root nodules of leguminous plants and some of them are free living soil bacteria such as azobacter.
These bacteria only form symbiotic relationship with the root leguminous plants but not with other plant families.
