Answer:
Some of the environmental issues that are related to agriculture are climate change, deforestation, dead zones, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Explanation:
Answer: position of the carbonyl carbon
Explanation:
In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.
Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.
But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.
In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.
In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon
Answer:
p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.
Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.
For both actin and microtubule polymerization, nucleotide hydrolysis is important for controlling the growth of a microtubule.
Polymerization dynamics enable microtubules to adopt rapidly changing spatial arrangements and, in some cases, perform mechanical tasks according to cellular needs. Microtubules harness the energy of GTP hydrolysis to drive a unique polymerization mechanism called dynamic instability.
Microtubules are one of the main components of the cytoskeleton and are rigid hollow rods approximately 25 nm in diameter. microtubules. are made up of dimers of α- and β-tubulin which polymerize to form microtubules, which are composed of 13 protofilaments assembled around a hollow core.
