Answer:

The false statement(s) is option(3).

That is,

Only one cycling is required per cell cycle 'is false'

Explanation:

Cyclins combine with Cyclin-Dependent protein kinase(CDKs) to form a complex cyclin-CDKs.

This complex comprise so many cyclin, per cycle. This shows that it is a false statement that only one cyclin is required per cell cycle.

The name "Cyclins" came up because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex.

This complex then acts as a signal to the cell to pass to the next cell cycle phase.

After a particular phase, the cyclin degrades, deactivating the Cdk, thus signaling exit from a the phase.

Answer:

Numbers 3) Only one cyclin is required per cell cycle, is false

Explanation:

Cyclins and cyclin-dependent kinases (Cdks) are responsible for modifying target proteins and act in various check points to progress the cell cycle. Four (4) cyclins are involved in this process in the cell cycle.

mamaluj [8]
Most woolly mammoths went extinct roughly 10,000 years ago amid a warming climate and widespread human hunting. But isolated populations survived for thousands of years after that on St. Paul Island in the Bering Sea and Wrangel Island in the Arctic Ocean

Why do homologous chromosomes crossover during pro prophase l?
Reil [10]
Crossover occurs when two chromosomes, normally two homologous instances of the same chromosome, break and then reconnect but to the different end piece. If they break at the same place or locus in the sequence of base pairs, the result is an exchange of genes, called genetic recombination.
