Answer: Option a
Explanation:
Biotechnology is the branch which deals with the most advanced techniques which is required to make the life easy.
One of the most important application is Genetically modified crops. Genetically modified crops are pest resistant and have many advantages.
There are few disadvantages one of them is beneficial insects are also adversely affected. There are many useful insects that helps in pollination and they are also killed because of pest resistant plant.
hence the correct answer is option A
Answer:
The correct answer will be option-D
Explanation:
RNA or ribonucleic acid is the nucleic acid which was formed in the primordial time. The RNA molecule acts as an enzyme called ribozyme and also acts as the genetic material of a few viruses.
The RNA is composed of nucleotide monomer where each nucleotide is made of a ribose sugar, a phosphate group and the nitrogenous base adenine, uracil, cytosine and guanine.
Thus, option-D is the correct answer.
The answer should be C, 50%
First we need to find the alleles for Mr Jones. We know that he has a blood type B, so at least one allele should be B, and the other can either be B or O (cannot be A, or else his blood type would be AB because A and B are co-dominant alleles)
Since Mr Jones' parents are both blood type AB, so which means their allels must be A and B, so, we can conclude that Mr Jones alleles should be B and B.
Now we know Mr jones' alleles, we can conduct a punnett square to find the probability. Since Mrs Jones has blood type AB, again, her alleles are also A and B.
From the punnett square attached, we can conclude that their offspring are either blood type AB or pure B. So, the answer should be 50%, C.
The difference between the two DNA sequences, is that there was a C added to the new sequence. This mutation is called insertion
