Answer:
The correct answer will be option-C
Explanation:
The CsCl gradient centrifugation in Meselson Stahl experiments is done to separate the bands of the DNA containing isotopes on the basis of difference in the density.
In the experiment, bacterial cultures were grown in the medium of 15N and 14N but if we repeat the experiment with P32 and P31 instead of 15N and 14N and centrifugation is performed then the banding pattern will be the same as of the previous experiment as the method of the replication is same that is semi-conservative.
Thus, Option-C is the correct answer.
RNA has great capability as a genetic molecule; it once had to carry on hereditary processes on its own. It now seems certain that RNA was the first molecule of heredity, so it evolved all the essential methods for storing and expressing genetic information before DNA came onto the scene.
Answer:
The correct answer would be:
- mRNA sequence - UCACGGAAG,
- amino acid sequence - Ser-Arg-Lys, and
- body type - dwarf
By central dogma, we know that nucleotide sequence of deoxyribonuceic acid (DNA) form the amino acid sequence of a polypeptide chain.
Nucleotide sequence of DNA is first decoded in the form of nucleotide sequence of mRNA (messenger ribonucleic acid) under the process of transcription. The sequence of RNA is complementary to the nucleotide sequence of template strand of DNA. In addition, uracil is present in RNA in place of thymine.
tRNA (transfer RNA) then deciphers the codon sequence of mRNA into amino acid sequence of polypeptide sequence by the process of translation.
Now, given DNA sequence is AGTGCCTTC.
so, the mRNA sequence would be UCACGGAAG.
Codon sequence is UCA CGG AAG.
So, the amino acid sequence would be Ser-Arg-Lys.
Hence, the trait of showman performer would be dwarfism.
