If DNA contained sulfur instead of phosphorus and proteins contained phosphorus instead of sulfur, what would have been the outcome of Hershey and Chase experiment?
1 No radioactive sulfur in bacterial cells
2 Both radioactive sulfur and phosphorus in bacterial cells
3 Radioactive sulfur in bacterial cells
4 Radioactive phosphorus in bacterial cells
Explanation:
They used radioactive sulfur in bacterial cell to label and, so, distinguish viral proteins from viral DNA. After allowing labeled viruses to infect bacteria, they observed that the radioactive phosphorus enters the bacteria while the radioactive sulfur always remains outside. - Protein contains sulfur but no phosphorus. By growing viruses in separate cultures, they ensured that one sample has only radioactive DNA while the other had radioactive protein. This would allow them to conclude which material was injected by the virus into the bacterium.

Which of the following statements is correct?
1 Adenine pairs with thymine through one \(\mathrm{H}\) bond
2 Adenine pairs with thymine through three \(\mathrm{H}-\) bonds
3 Adenine does not pair with thymine
4 Adenine pairs with thymine through two \(\mathrm{H}-\) bonds
Explanation:
Adenine (A) pair with thymine (T) through two \(\mathrm{H}\)-bonds. - cytosine (C) and guanine (G) pairs together by three H-bonds.

What is not true about alleles?
1 Round and wrinkled form of genes are alleles of each other
2 Only recessive alleles expresses in hybrid
3 Alleles occupy same loci on homologous chromosomes
4 Two or more alternative forms of gene are called alleles are allelomorphs
Explanation:
Alleles occupy same loci on homologous chromosomes.

Chromosomes in a bacterial cell can be 1-3 in number and. -
1 Are always circular
2 Are always linear
3 Can be either circular or linear, but never both within the same cell
4 Can be circular as well as linear within the same cell
Explanation:
Exp. A Nuclear material of bacteria lies free in the cell in the form of an irregular, thin, fibrillar and circular single molecule of DNA, called nucleoid or chromatin body. In addition to circular DNA, a small amount of subsidiary extra chromosomal DNA is also present as plasmids or episomes.

Satellite of chromosome is
1 Rich in RNA and deficient in DNA
2 Rich in DNA and deficient in RNA
3 Rich in protein
4 Lacks DNA
Explanation:
Satellite DNA is a type of non-coding DNA that is characterized by repeating sequences of DNA that do not code for proteins. Satellite DNA is indeed known to contain regions rich in RNA sequences and many have limited amounts of DNA.
