I think what happens is that the Cyclin component of the MPF is degraded. MPF or mitosis promoting factor, consists of two important cell cycle regulatory protein called the cyclin and cyclin dependent kinases (CDK). The cdk and the cyclins are the major control switches for the cell cycle, causing the cell to move from G1 to S or G2 to M.
Answer:
Transamination reaction:
Transmaination reaction may be defined as a type of chemical reaction that involves the transfer of an amino group to the another keto acid fort the formation of new amino acid. The non essential amino acid can be easily converted to essential amino acid by this transmination reaction.
This reaction is important for the important mteabolic pathways of the body. The cofactor required for the transamination reaction is pyridoxal-5'-phosphate. This cofactor also works as a derivative of vitamin B6. This cofactor is converted to pyridoxamine-5'-phosphate during the reaction.
Answer:
C)Alcoholic and lactic acid
Answer:
A. Rock pieces
Explanation:
Abrasion is the breaking down and wearing away of rock material by the mechanical action of other rocks. Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. None of those are agents of abrasion. But Rock pieces are a result of abrasion.
This question is incomplete. The options are:
a. Oligocene b. Eocenec. Miocene<span>d. Pleistocene
</span>Option b is correct. This relates to the Paleocene-Eocene Thermal Maximum (PETM) which occured around 56 million years ago and was similar to modern-day climate change. Warming of more than 5 degrees Celcius occured over<span> 15-20 thousand years because of input of more than 2000 gigatons of carbon into the atmosphere. The PETM resulted in mass deep ocean extinctions and mass terrestrial and shallow ocean diversification.</span>
