Answer:
At the end of DNA replication, each copy is identical to each other (option A).
Explanation:
The concept of DNA replication implies that, from an original molecule, two identical molecules are obtained.
DNA replication is based on a semi-conservative model, since the double strand is separated, and each strand serves as a mold for the synthesis of a new strand. <u>At the end of the replication, two identical DNA molecules will be obtained, each consisting of an original strand and a new one</u>.
The best evidence that the replication process results in two identical molecules is that, otherwise, an individual's genetic information could vary, which does not happen.
The other options are not correct because:
<em> B. The copies cannot be different.
</em>
<em> C and D. They are 100% identical, not partially (50 or 90%) similar.</em>
The doctor <span>suspected that this characteristic was the result of a</span> somatic mutation that happened in the developing embryo, but probably wouldn't affect the daughter's egg cells.
The answer is B - Archea, Bacteria, and Eukarya are all Domains
Answer:
staphylococci
Explanation:
Gram stain -
it is the method of staining which classify the species of the bacteria into gram - positive and gram - negative .
This method distinguish the bacteria by its physical and chemical properties of the cell well of the bacteria .
1. In case of gram - positive , the stain is of color violet , because to its thick cell wall .
and ,
2. In case of gram - negative , the stain is of pink color , because to thinner cell wall .
The bacterium , which shows Gram - positive coccus after the gram stain is staphylococci .
Yes, both are true. Please give me brainliest! ☆
