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.
Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2
Answer: Option D) Peptide bonds are amide linkages.
Explanation:
A peptide bond is formed between two amino acids with the loss of one molecule of water and the formation of an amide (CO-NH2) bond.
Usually the carboxyl group (COOH) of the first amino acid links with the amino group (NH2) with the loss of H2O, thus forming an amide linkage
Answer:
Explanation:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
