Mitosis and Meiosis

Which is not the function of mitosis

• repair and replace damage tissue

• essential for asexual reproduction

• multiply chromosomal number

• allowing growth and development of organism

In which phase of mitosis will chromosome pull to the opposite pole of cell

• early prophase

• late prophase

• metaphase

• anaphase

In which stage does DNA synthesis

• G1

• S

• G2

• Mitosis

What is M in the diagram

• metaphase plate

• spindle fibre

• centrioles

• centromere

How many chromosome and chromatid are there in this cell

• 8,4

• 8,8

• 4,8

• 4,4

Homo sapiens has how many chromosomal number in its cell

• haploid number of cell, n=23

• diploid number of cell, n=23

• haploid number of cell, n=46

• diploid number of cell , n=46

Which sequence indicates the correct tissue culture technique

• explants, aggregates of cell, callus, embryo, plantlet

• explants, aggregates of cell , plantlet, callus, embryo

• explants, callus, aggregates of cell , embryo, plantlet

• protoplast, callus, aggregates of cell, embryo, plantlet

Which is not the advantage of cloning

• produce large number of cell in shorter period

• transgenic crops has stronger desirable characteristics and trait

• ethical issue will rise

• vegetative propagation can be carried out

Which stage will crossing over of non sister chromatid occur

• Interphase

• Meiosis 1

• Meiosis 2

• S phase

Which is the similarities between mitosis and meiosis

• genetically identical to parent cell

• genetic variation occur in daughter cell

• sister chromatid move to opposite pole during anaphase

• DNA replication occurs once
