#Unit 2. Cellular Organization

Active cytoplasmic cyclin B-CDK1 translocates into the nucleus, where it phosphorylates nuclear lamins to cause nuclear envelope breakdown and, together with Plk1 and the Aurora kinases, induces chromosome condensation and formation of the mitotic spindle.

                                                               β-turns

Most common turns, also termed as ẞ-bends, tight turns, reverse turns, generally connects

β-sheets.

The conformation of i+1 and i+2 are crucial and on the basis of this, they are classified

Consists of 4 amino acids, generally termed as i, i + 1 , i + 2 and i + 3

H-bond is seen between i and i+3 (First and Fourth residue)

#Unit 6. System Physiology – Plant

Three major types of insect herbivores

Phloem feeders, such as aphids and whiteflies, cause little damage to the epidermis and mesophyll cells. Phloem feeders insert their narrow stylet, which is an elongated mouthpart, into the phloem sieve tubes of leaves and stems.
