lakkis [162]

Answer:

1. Weaker

2. Continuous

Explanation:

A tumor suppressor gene codes for retinoblastoma protein (pRb). The retinoblastoma protein binds to transcription factor E2F when DNA damage is detected. The E2F bound to pRb can not stimulate expression of genes that code for proteins required during the process of DNA synthesis. The cell can not enter the S phase.

On the other hand, when the retinoblastoma protein is phosphorylated by cyclin E-CDK2, E2F transcription factor is free to stimulate the expression of genes required for DNA synthesis and the cell proceeds from G1 to S phase.  

When the mutated retinoblastoma gene code for a protein that serves as phosphorylated protein, it will not be able to bind strongly with E2F and there would be continuous expression of genes required for S phase.

Arturiano [62]

Answer:

Explanation:

Endocrine cells in the pancreas are referred to as Islets of Langerhan. There are two major types; Beta cell that produce insulin and alpha cells that produce glucagon.

They are identified when viewed under slides based on their colour reactions with histological dyes. Tinctorial techniques that can be used to identify them under microscope includes; Mallory-Heidenhain azan trichrome, chromium hematoxylin and phloxine, aldehyde fuchsin, and silver impregnation methods.

Islets of Langerhan cells make up minority of the cell. Majority of them are for exocrine functions.
