<h2>Cytokinesis in animal cells</h2>
Explanation:
- The force for cytokinesis is generated by kinesin motors on microtubule bundles that form the contractile ring:This statement is false because cytokinesis in animal cells starts with the assembly of contractile ring,contractile band consists of actin and myosin(microfilaments) which catalyse cleavage furrow formation
- As the contractile ring constricts, its thickness increases to keep a constant volume:This statement is false because thickness remains constant
- The midbody forms from bundles of actin and myosin: This statement is false because contractile ring forms bundles of actin and myosin whereas midbody is formed from microtubules
- Local activation of Ran GTPase triggers the assembly and contraction of the contractile ring:This statement is false because local activation of Rho mediates profilin binding to actin and helps in assembly and contraction of contractile ring
The four letter string comes out to be FFFF
It is called genetic engineering
The fraction of offspring with black coat color and straight fur is 9/16.
Explanation:
Information given:
black coat colour and straight fur - dominant genotype BBCC, BbCc
yellow coat colour and curly fur - recessive genotype bbcc
Both the traits are independently assorted. The fur colour and fur type is not present on the same chromosome and are not sex linked.
The genotype of the parents are:
BbCc X BbCc
Punnet square shows:
BC Bc bC bc
BC BBCC BBCc BbCC BbCc
Bc BBCc BBcc BbCc Bbcc
bC BbCC BbCc bbCC bbCc
bc BbCc Bbcc bbCc bbcc
9 BLACK STRAIGHT
3 BLACK CURLY
3 YELLOW STRAIGHT
1 YELLOW CURLY
9/16 is the fraction of progeny to be black coat colour and straight fur.
Eu means true therefore it is known as eubacteria
