1, O because if either shows present it's O.
Explanation:
Organic polymers are macromolecules composed of many repeating monomer units. Both synthetic and natural polymers play a crucial role in everyday life. Polysaccharides, polypeptides, and polynucleotides are the main types of biopolymers in living cells.
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly. I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.
Hi,
If a point mutation occurs during which CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.
This is because, both AGA and CGA code for same amino acid called Arginine.
We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism
Hope it helps!:)
