Answer:
The correct answer will be- 21, 29, 29
Explanation:
In a DNA sequence, the nucleotide base pairs on one strand of DNA are complementary to the base pair on other strand of DNA.
According to the Chargaff rule, Adenine binds Thymine and Cytosine binds Guanosine which shows that the amount of A will equal T and the amount of G will equal C.
Therefore, when the amount of C is 21%, then the amount of G will be 21%.
To find amount of AT= 100-GC
AT= 100-42
AT= 58%
So, AT/2= 29% each
Thus, A=T= 29%
G=C=21%
The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.

Answer:
Option (B).
Explanation:
The relationship between closely related species can be studied by their evolutionary tree. The two species are closely related if they have similar characteristics and nucleotide sequence.
Species A has the DNA sequence TAGCTTAGGGACGG whereas species B has the DNA sequence TACCTTAGGGACGG. These two species have identical nucleotide sequence with minor differences. Hence, these two species are closely related with each other.
Thus, the correct answer is option (B).
Answer: meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
