Which statement is not true about RNA?
Unlike DNA, RNA is not a double-helical structure. RNA is never meant to live long. It has the same template as that of the DNA which is further taken to the ribosomes where the protein transcription is exchanged. RNA is the template of DNA that can be used and then disintegrated.
Which of the following is incorrect regarding RNA?
(b) RNA is the only genetic material in viruses is the incorrect answer.
Which of the following statement is true about RNA?
It contains adenine paired to thymine.
Which of the following statement is false about RNA polymerase?
The RNA polymerase is going to enter the gene through the promoter option. Business, it synthesizes marinating a 3 to 5 direction within the DNA strand 5 to 3. And this is false.
Which of the following statement is incorrect regarding DNA?
The two strands in DNA molecules are complementary to each other. IV. DNA strand contains pentose – 2 – deoxyribose sugar. Thus, option (C ) is incorrect.
Which of the following is false about denaturation?
Which of the following is false about denaturation? Explanation: Phosphodiester linkages are not broken by denaturation.
Which of the following statement is incorrect about SnRNA?
9. Which of the following statement is Incorrect about SnRNA? Explanation: SnRNA is small nuclear RNA mainly found in the nucleus of eukaryotic cells. It takes part in RNA splicing and always remain associated with other proteins and referred to as snurps or snRNP.
Which base is present in RNA but not in DNA?
Uracil. Uracil is present in RNA and binds to adenine whereas thymine is present in DNA and binds to adenine.
Which of the following is correct about RNA in eukaryotes?
Exons appear, but introns do not appear in the mature RNA is correct about mature RNA in eukaryotes.

Which of the following statements are incorrect 1 RNA acts as a genetic material as well as a catalyst 2 RNA is more stable than DNA 3 RNA has evolved from DNA?
Option 2 is incorrect because DNA is more stable than RNA
Give reasons by first discussing the desired criteria in a molecule that can act as genetic material and in the light of biochemical differences between DNA and RNA. The presence of genetic material as DNA or RNA is the characteristic of _________.
Which of the following statements is not correct for viruses?
Viruses do not have DNA or RNA.
In which RNA acts as genetic material?
[i]ssRNA : TMV, Polio cirus, HIV (Retrovirus), mumps virus, measles virus, Rabies virus, influenza virus, Papaya mosaic virus, QB bacteriophage.
Which of the following RNA acts as a genetic material?
HIV, which is a retrovirus, has RNA as its genetic material instead of DNA.
Which one of the following is an incorrect statement for a tRNA molecule?
Select the incorrect statement about tRNA. <br>(a) tRNA possess an amino acid acceptor at 3′ end for binding of amino acids. <br> (b) tRNA is also called soluble RNA. <br> (c) Only single tRNA exists for all 3 stop condons<br> (d) tRNA posses an anticodon loop that has bases complementary to the code.
Which is correct a RNA is genetic material of bacteria?
The genetic material of bacteria and plasmids is DNA. Bacterial viruses (bacteriophages or phages) have DNA or RNA as genetic material. The two essential functions of genetic material are replication and expression.
Which one of the following is an incorrect statement with regard to pedigree analysis?
Pedigree analysis cannot confirm that DNA is the carrier of genetic information because it is an analysis system. For DNA based experiments, molecular biology techniques are used.
Why is RNA hypothesized to have been the first genetic material?
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.
Can RNA catalyze reactions?
Ribozymes are RNA molecules that accelerate chemical reactions, enzymes that happen to be made of RNA rather than protein. Two of the cell’s most important reactions are catalyzed by RNA. …
What is the pattern of inheritance in the above pedigree chart?
Option (B) Autosomal recessive is the correct answer. The pattern of inheritance in the above pedigree chart is Autosomal recessive.
What is a genetic test cross?
In its simplest form, a test cross is an experimental cross of an individual organism of dominant phenotype but unknown genotype and an organism with a homozygous recessive genotype (and phenotype).
