Answer:
Protein A can be a cytoplasmic and protein B can be a membrane protein.
Explanation:
The polar amino acid will have the hydrophilic side chain so they provide the hydrophilic nature to protein and thats why usually found on outer surface of water souluble proteins.
Cytoplasm is 80% water, so these proteins usually found in cytoplasm.
The non-polar amino acid will have the hydrophobic side chain and thus provide hydrophobic nature to protein and usually found in interior portion of membrane protein.
Plasma membrane is made up of hydrophobic lipids bilayer, so these proteins are usually found in plasma membrane.
The answer is 0.42.
According to the Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p is a frequency of a1 allele, q is a frequency of a2 allele, p² is a frequency of a1a1 genotype, 2pq is a frequency of a1a2 genotype, q² is a frequency of a2a2 genotype.
If <span>70% of the gametes produced in the population contain the a1 allele, then:
p = 70% = 0.7.
If p = 0.7 and p + q = 1, then q = 1 - p = 1 - 0.7 = 0.3
So, the proportion of </span>the flies that carry both a1 and a2 (a1a2 genotype) is:
2pq = 2 * 0.7 * 0.3 = 0.42
Answer:Gully
Explanation:Search up a gully and you will see :/
Ans.
Memory cells of immune system are present in G0 phase, in which these cells are not activated or responding for a pathogen.
The cell-cycle is defined as the series of events that lead to DNA duplication and division of a cell to form daughter cells. The cell cycle is divided into interphase and M phase.
The interphase includes gap 1 (G 1) phase, S or synthesis phase, and gap 2 (G 2) phase, while M phase includes karyokinesis and cytokinesis.
The cells after M phase either goes for next cell division or G1 phase or for G 0 (gap 0) phase. The G0 phase is resting phase, in which cells show a quiescent state.
As memory cells are present in resting phase, till the next exposure of same antigen, these cells are in G0 phase of cell cycle.
