If two organisms show a developmental homology you would also definently expect them to?
san4es73 [151]

If two organisms show a developmental homology you would also definitely expect them to share genetic homologies.

Homology is the similarity between two organisms. This similarity can be of body structures, physiology, etc. This homology is generally due to shared ancestral history between two organisms. For example, the wings of a bird and bats are homologous structures, this is because they have a common anatomy.

Genetic homology refers to the arrival from the same gene from a common ancestor. The same gene is shared between two organisms who may not be related in any other matter. Genetic homology can even be depicted by the sequences of a protein.

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.
