Yellow River Civilization
Answer:
Explanation:
The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.
Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.
Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.
In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.
The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.
DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
Answer:
I would have to say c I have learned this type of stuff in the past
Answer: REABSORPTION
Explanation: Reabsorption or tubular reabsorption is one of the processes involved in urine formation,the other two(2) being ultra filteration and and active secretion.
Reabsorption takes place mainly in the proximal convulated tubule of the nephron, nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration re-enter the blood from the renal tubules,moving solutes out of the filtrate and back into the bloodstream.these solutes that are moved back into the bloodstream goes back into circulation alongside with the blood because it is needed for the normal functioning of the body system and maintanance of homeostasis.
In a situation where tubular reabsorption does not occur as a result of certain conditions like hyposecretion and diabetes insipidus,there will be imbalance of ions in the body as a result of useful ions leaving the body via urine and the body is left with ion deficiency.
