Coagulative necrosis

Explanation:

  • When cell death occurs due to ischemia or infarction then this is termed as Coagulative necrosis.
  • During this type of necrosis, cell death occurs in a localized area due to lack of oxygen and other nutrients.
  • When a two year old swallows watch batteries then these batteries becomes trapped in the digestive system and inside the digestive tract , the positive and negative terminals of the battery gets bridged by the mucosa leading to the production of the electrical current and increase in the pH of the mucosa.
  • All these condition leads to coagulative necrosis due to which the kidney gets affected and heart failure occurs .

If adenine didn’t always pair with thymine and guanine didn’t always pair with cytosine, the new DNA ladders wouldn’t always be
zloy xaker [14]

Answer:

they wouldnt be identical because for example Guanine could be paired with thymine in the original DNA strand but could decide to pair with adenine in the replication DNA. that would make a different type of DNA.

Explanation:

DNA replication is a beautiful process. In DNA replication adenine only pairs with thymine and guanine only pairs with cytosine. this ensures that a replication of the DNA will be the same type of DNA.

Replication works like this. Helicase splits open the DNA and each side is copied by DNA polymerase. If let's say the nucleotide bases for side 1 are ATGCGA then the DNA polymerase will pair these with the matching bases TACGCT which will make the same DNA but if each base could pair with any base they want that could create a few different variations of the original DNA. ATGCGA could very well be paired with TCGACA or CGACTA which would created two different types of DNA.
