Question

name the following:
i) The phase which is followed by mitotic division and during which the cells prepare
for the next cell-division and grow
ii) The phase of mitotic cell division during which RNA and proteins are synthesized
and the volume of cytoplasm increases.
ii) The phase of mitotic cell-division during which chromosomes get lined up in one
plane at the equator
v) The mixing up of the maternal and paternal chromosomes during the first meiotic
division as they separate from the homologous pairs ....
v) The point of intersection where rejoining of some of the broken chromatids of
homologous chromosomes takes place during pairing
What are chromosomes ?


​

Answer 1

i) The phase which is followed by mitotic division and during which the cells prepare - Interphase

ii) The phase of mitotic cell division during which RNA and proteins are synthesized - S phase/ synthesis phase

ii) The phase of mitotic cell-division during which chromosomes get lined up in one

plane at the equator - Metaphase

v) The mixing up of the maternal and paternal chromosomes during the first meiotic

division as they separate from the homologous pairs-- Crossing over

v) The point of intersection where rejoining of some of the broken chromatids of

homologous chromosomes takes place during pairing--Chiasmata

What are chromosomes ?

Chromosomes are thread like structures in the nucleus that transfer hereditary information from one generation to another

Answer 2

Answer:

i) Interphase

ii) First growth phase

iii) prophase

iv) reduction

v) crossing over

vi) The nucleus contains most of the cell's DNA which is organized into discrete units called chromosomes.
