Answer:

involves cleavage of the pre-mRNA

Explanation:

In eukaryotic organisms, the mechanism of transcription termination of protein-coding genes involves two different processes: 1-the site-specific cleavage of the precursor messenger RNA (pre-mRNA) sequence in the 3'-untranslated region (3'-UTR), and 2- the separation of RNA polymerase II (Pol II) from the DNA template. In regard to the cleavage of the pre-mRNA, it is a process followed by the polyadenylation (polyA) of the upstream cleaved product. The main function of the polyA tail is to protect the mRNA from enzymatic degradation. Moreover, the mechanism of transcription termination is accompanied by dephosphorylation of the C-terminal domain (CTD) of the large subunit of the RNA Pol II.

Predict how it is possible for bison's population to thrive in the prairie?
valentinak56 [21]

Answer:

Bison have limited type of natural predators.

Explanation:

A Bison is a land animal which has a similar appearance to that of a buffalo. They are known to be fast,agile and strong.

A prairie habitat is an ecosystem that is considered part of the temperate grasslands, savannas, and shrublands biome by ecologists due to the similarities in the temperate climates, moderate rainfall and composition of grasses, herbs, and shrubs instead of trees as the main and common vegetation type.

This habitat consists of animals and reptiles such as bison, coyote, antelope, badger, elk, prairie dog, otters, foxes,lizards.

This represents a limited number of predators for the Bison

Carbon dioxide with its two double bonds is an example of a polar molecule.
GarryVolchara [31]
The bond between one carbon atom and one oxygen atom is polar but due to the fact that there is another oxygen attached to the carbon which has the same electronegativity value as the oxygen on the other side, the effect of polarity is canceled. CO_{2} is non-polar because the oxygens symmetrically alligned on the opposite sides of the carbon cancel the polarity effect.

Peptidoglycan in the bacterial cell envelope is an ideal target for antibiotics because ______.
bulgar [2K]

Peptidoglycan in the bacterial cell envelope is an ideal target for antibiotics because Antibiotics limit bacterial growth and replication by interfering with the bacterial cell wall.

  • Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
  • The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.
  • Simply put, a lot of antibiotics, like vancomycin, which like -lactam antibiotics targets the peptidoglycan in the cell wall, are ineffective against,
  • Gram-negative bacteria because they lack the molecular characteristics necessary to employ these pathways to efficiently breach the outer membrane.

A diabetic, who does not utilize insulin properly, will metabolize fats instead of glucose. A condition called diabetic ketoacid
Readme [11.4K]

Answer:The correct answer to the question is option D

THE PH IS BELOW NORMAL (ACIDIC) BECAUSE THE BUFFERING CAPACITY WAS EXCEEDED.

Explanation: When insulin is being utilized well by a diabetic,glucose is metabolized because the insulin administered helps the body cells to pick up glucose from the food we eat and convert it to energy for the body to work with and function well.But when insulin is not being utilized properly by a diabetic,fats are metabolized instead of glucose that is to say that,the cells in the body are not sensitive to the glucose supplied by the food we eat which makes the body to be hypoglycemic (low blood glucose level),the body inorder to raise the blood glucose level starts breaking down stored fats in the body at a rate that is higher than normal inorder to provide energy, the liver then processes the broken down fats into a fuel that is known as ketones, these ketones are released into the blood causing the blood to be acidic,the buffering property of blood on a normal note is suppose to resist the changes in the PH of the blood,but when the buffering capacity is exceeded,there won't be any resistance to the change in the blood PH which will inturn lower the blood PH level making it acidic.

This is exactly what happened to the diabetic being described in the question.
