<span>The question says, 'which component of a virus is lacking in a cell. The answer is capsid. virus capsid are protein shell of a virus, they envelope the virus and protect it from harm. Cells does not have capsid, they have rigid cell wall instead. The rigid cell wall protect the cell from harm and also give the cell shape.</span>
(4,0)(-4,0) Is the correct answer :)
Answer:
Option-D
Explanation:
In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.
1. Unlinked genes
Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which
1. A_B_ are 9
2. aaB_ are 3
3. A_bb are-3
4. aabb- 1
Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.
2. Linked genes
When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are- Ab and aB and the recombinant frequency will become less.
Crossing these allele will form Aabb
, AaBb
, AaBb and aaBB genotypes.
The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.
Thus, option-4 which states that the unlinked ration is 9:3:3:1 and linked ratio is <9: >3: >3: <1 is correct.
Answer:assuming it is LiAlSi2O6, you have lithium, aluminum, silicon, and oxygen. It’s difficult to tell with all of the letters capitalized. Only the first letter of the atom should be capitalized. A capital I is iodine.
Explanation:
We see the so called " near side " of the moon. Because the moon spins in the exact rotational period we see the same side of the moon every time we look at it .
