C is a combustion reaction
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.
Two identical DNA strands
Answer: crossing over
during the process of fertilization, a sperm and egg join together to create a zygote. since a sperm had half the number of chromosomes and an egg has half the number of chromosomes, when they join together the zygote had a complete diploid set of chromosomes. the assortment of chromosomes and crossing over promotes genetic variation during the process of reproduction
Answer: (A) the time that two species have been evolving independently.
Explanation: The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when<u> two or more life forms.</u>
