Question
sh Parent 2 0000 Paret l hAgg-- (purple, smooth) (yellow, wrinkled) GI-chromosomes have not been duplicated. What are they doing in G1? When are the co Prephase I - each chromosome has been duplicated. The two copies lie side by side, connected by the centromere and are called sister chromatids m. Metaphase 1- the 400 next to cach other at the center of the cell The first cell division Metaphase II - sister chromatids still attached by the centromere, line up in the center of the cell. The second cell division separates the sister chromatids one gamete from cach parent to obtain the FI individuals in the next pages Genotype: AaBb Fi Phenotype: pur 36Explanation / Answer
Cell cycle is a series of cyclic changes through which a cell passes during the growth and and divisions. Time interval between two successive divisions is called generation time.
1. Long nondividing I-phase and 2. short dividing M -phase.
Interphase is a complex of changes that occurs in a newly formed cell before it is able to divide. It can be divided into three stages that is (i)G1 phase
(ii) S Phase
(iii) G2 phase
G1 phase is the first growth phase where the cell and its nucleus grow in size. This phase occurs after mitotic phase and due to this reason it is also known as post mitotic gap phase. In this phase RNA and protien including histone synthesis occurs. Most of the protiens are synthesized during this phase. Not only this, during this phase the cell synthesizes most of the enzymes and various nutrients that are needed later on during DNA replication and cell division.
