Answer:
Motor protein kinesin can "walk" along a microtubule while carrying vesicles and by changing its shape the kinesin.
Explanation:
Motor protein kinesin is an important microtubule based motor protein that is conserved among all eukaryotic organisms. Its movement along the microtubule is ATP powered. Most of the kinesins walk towards the plus end of the microtubule.
Due to its ability it is responsible for unidirectional transportation of cargos including membranous organelles and mRNA.
When a cell is in G2 phase, it has already doubled in S phase its DNA, meaning that for each chromosome we have two chromatids -> 2n(number of chromosomes)×2(number of chromatids per chromosome)=number of chromatids.
If 160 is the number of chromatids on G2 phase of a chicken cell, it means that the cell has 80 chromosomes (2n), and after meiosis, process to form a sperm cell, will only have 40 chromosomes (n).
