Answer:
The correct answer is option B.
Explanation:
On seeing the question, it is clear that it is based upon the concept of semi-conservative theory for the replication of DNA. It is mentioned that when the bacteria were grown on N-15, the mass was 55 fg. Now, after two generations, the DNA would comprise N-14 and the mass of them will be 5.4 fg.
The average mass would be = 5.4 + 5.5 / 2 = 10.9 / 2 = 5.45 fg. The mass of the bacteria isolated from the culture would possibly contain both the masses. That is, the mass of DNA with N-14 only would be 5.4 fg, and the mass of DNA with both N-15 and N-14 would be the average, that is, 5.45 fg.
When water molecules are being made, two hydrogen atoms will make a hydrogen bond with one oxygen atom, making a water molecule.
Answer:
A cross between two pure breeding tall (TT) and dwarf (tt) parent plants produce uniform F
Explanation:
generation of dominant individuals (Tt).
According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual; the allele/factor that can express itself in a heterozygous individual is called as a dominant trait. Another factor whose effect is masked by the presence of a dominant factor is called a recessive factor. The recessive factor, t, is present in F
hybrids but its expression is masked by the factor for a dominant trait, T.
