Most viruses have<span> either </span>RNA<span> or </span>DNA<span> as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious </span>virus<span> particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest </span>viruses contain<span> only enough </span>RNA<span> or </span>DNA<span> to encode four proteins.</span>
Sorry but I’m don’t know these things
You need to test the hypothesis several times and record all results. Once you obtain the same results several times, I think that means its a theory
<span>It's simple. There's creal definition of gene isolation technique. So the answer is: The type of genetic engineering that often involves isolating genes from one species and introducing them into another is called gene isolation technology.</span>
Answer:
The correct answer is D sister chromatids;centromere
Explanation:
After DNA replication during s phase or synthesis phase of interphase of the cell cycle,each chromosome has a copy and the cell that is newly formed is now 4n.
We cal these identical pairs sister chromatids and they are held together by a centromere
