The molecular biology technique of reverse genetics can be useful for determining the function of a gene.
<h3>What is reverse genetics?</h3>
Reverse genetics is method use in molecular biology to determine gene function in an organism
The procedure in reverse genetics involves modifying or certain nucleotide sequences in the DNA coding for a functional gene and then observing changes to the phenotype of the organism brought about by the modifications.
Therefore, reverse genetics can be useful for determining the function of a gene.

Answer:
the cytoplasm is negative and extracellular fluid is positive because of the unequal distribuation of anions and cations on both sides.
Explanation:
Answer: Option B)
Im 100% sure its the 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.
Human bodies contain enzymes that can break down starch into glucose and use it for fuel. We do not have the enzymes necessary to breakdown cellulose.
