1,. A and B are permanent dipoles and are involved in hydrogen bonding.
2. A and B are fully ionized and are involved in salt bridge formation.
3. A and B are uncharged and repel each other.
4. A and B are uncharged and attract each other.

. You have created a fusion between the rrp operon, which encodes the enzymes for tryptophan biosynthesis, under the regulatory control of the lac operator. Under which of the following conditions will tryptophan synthase be induced in the strain that carries the chimeric operator fused operons?
1. Only when both lactose and glucose are absent.
2. Only when both lactose and glucose are present.
3. Only when lactose is absent and glucose is present.
4. Only when lactose is present and glucose is absent.

Which of the following is NOT associated with insulin action?

1. dihydrofolate reductase.
2. thymidine synthase.
3. thymidine kinase.
4. adenylate cyclase.

Which class of immunoglobulins will increase in case of a chronic infection?

When prospective neuroectoderm from an early amphibian gastrula is transplanted in the prospective epidermal region of a recipient (early gastrula) embryo, the donor tissue will give rise to
1. neural tube.
2. epidermis.
3. neural tube and notochord.
4. neural tube and epidermis.

Amphibian oocytes remain for years in the diplotene stage of meiotic prophase.
Resumption of meiosis is initiated by
1. gonodatropic hormone.
2. growth hormone.
3. oestrogen.
4. progesterone.

A group of six cells called 'equivalence group cells' divide to form the vulval structure in Caenorhabditis elegans. They are called so because
1. they have similar fates during development of vulva.
2. all the six cells are competent to form vulva and can replace each other under various
experimental conditions.
3. they are all under the influence of the anchor cell, signals from which initiate
vulval development.
4. they interact with each other to form the vulval structure.
