Q.

Where is gene located?

Q. Genes are segments of DNA that contain the code for a specific protein.

1. False
2. True

Q. Difference between genome and DNA

Q. Write properties of genetic material. Explain with a diagram, the experiment of Alfred Hershey and Marthachase that DNA is a genetic material.

Q. A complete set of chromosomes inherited as a unit from one parent, is known as

1. Karyotype
2. Gene pool
3. Genome
4. Genotype

Q. Differentiate between.
Chromosomal mutation and genomatic mutation

Q. The distance between two genes in a chromosome measured in cross-over units which represent

1. Percentage of crossing over between them
2. Ratio of crossing over between them
3. Number of crossing over between them
4. None of these

Q. Transposons can move

1. To a specific site on a chromosome
2. To any site on a chromosome
3. To nearly any site on a chromosome
4. All of the above

Q. The largest gene in man is

1. Dystrophin
2. Insulin gene
3. Beta globin gene of haemoglobin
4. Tumor suppressor gene
5. Oncogene

Q. Meiosis II resembles mitosis except that:

1. Unlike that of mitosis, anaphase II of meiosis II does not involve separation of sister chromatids
2. Unlike that of mitosis, telophase II of meiosis II does not involve cytokinesis
3. Unlike that of mitosis, metaphase II of meiosis II does not involve alignment of the chromosomes on the equator of the cell
4. Unlike that of mitosis, prophase II of meiosis II is not preceded by doubling of DNA content
