Answer:
The options
a. 3:4
b. 3:1
c. 4:3
d. 4:9
e. 1:3
The CORRECT ANSWER IS e.
e. 1:3
Explanation:
Compound A (green) , GENE A is transformed to Compound B (blue)
Compound B (blue) , GENE B is transformed to Compound C (red)
After gene A as transformed the compund A to compound B, gene B can can transform the compound B to C. Therefore, once gene A is forming blue colour from green, gene B as the capability to form red colour from the blue one.
Lets cross AaBb X AaBb (the product of the cross is shown in the attached image. )
we will have the following genotypes:
AABB-1
AABb- 2
AaBB-2
AaBb-4
We obtain a functional copy of A and B gene from the cross. Thus, the transformation of colour will proceed from green to red and they will form red colour, giving us 9 red colour.
AA bb -1
Aa bb -2
The functional B gene is absent in these organism while the funtional A gene can be seen, thus only blue colour will be formed or 3 individual will give the blue colour.
aa BB -1
aa Bb -2
aa bb-1
these set of individual will not give or form any colour as they do not possess the functional A gene which is a requirement for starting the cascade of transforming the compounds.
Therefore, the blue to red offspring will be
3:9 or 1:3
The CORRECT ANSWER is e.
Explanation:
- Cytochrome c is a peripheral membrane protein
- Cytochrome oxidase is an integral membrane protein
Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers -they function as transport proteins, membrane enzymes and receptors, and cell adhesion molecules .
Further Explanation:
Integral membrane proteins are embedded and fixed within the membrane and flow from the extracellular fluid to the cytoplasm, and sometimes contain hydrophobic side chains which interact with phospholipids within the membrane which helps to anchor them; they contain one or more domains which span the protein. Multipass integral proteins cross the membrane several times whereas single pass integral proteins cross only once
Perpheral or extrinsic don't have interactions with the membrane's hydrophobic core. These are bound via interactions with polar phospholipid heads or other integral proteins and may be modified by the addition of fatty acids and lipids. They primarily function in transmitting messenger signals, to form temporary associations with the cell membrane and freely move unto the extracellular or intracellular space.
These carry out facilitated diffusion is used for the transport of large molecules unable to cross the plasma membrane at will. However, passive diffusion, describes the movement of substances (small molecules and ions) across the membrane, along their concentration gradient.
