mam I have a doubt in a sentence will u please explain?? the sentence is both in cells and extracellular fluids dibasic phosphate and monobasic phosphate act as a acid base buffer to maintain the H+ ion concentration of cellular fluids

A buffer is solution which resist pH change, it has weak acid and conjugate base. Phosphate buffer system is one of the body's chemical buffer systems. It consists of dihydrogen phosphate ions as acid that acts as donor of hydrogen ion and hydrogen phosphate as base that acts as hydrogen ion acceptor. It operates in internal fluids of all the cells.

mam doubt in a question if a cell at the initial stage of mitotic phase has 48pg DNA then the amount of DNA at the end of S phase and G1 phase??
Juhi Mishra
a year ago
During S phase of interphase amount of DNA get doubled so 48 picogram DNA will be doubled in its value. So DNA at the end of S phase is 96 pg. At G1 phase DNA amount will be 48 pg.

sorry mam for disturbing you mam will please explain difference between chromosome and chromatid
Juhi Mishra
a year ago
Chromatid is a chromosomal arm. 2 chromatids are arranged together and make 1 chromosome. Both chromatids are joined at a point known as centromere or primary constriction.

mam homologous chromosomes???
Juhi Mishra
a year ago
Chromosomes with similar shape,size,structure & no. of genes are referred as Homologous chromosomes. Eg. Paternal ( father) & maternal ( mother) chromosomes are homologous to each other.

Interphase has 4 subphases- G0,G1,S & G2 Then after Interphase M Phase/ Mitotic phase comes post means after m-phase Post means after. So, G1 phase comes after m- phase. then this phase is called post mitotic or Pre- synthetic phase( because it comes before S phase).
