A bacterium is infected with an experimentally constructed bacteriophage
dem82 [27]

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

  • The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
  • Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
  • As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

Explain why a hydrogen atom can become either an ion or a part of molecule?
NikAS [45]

<span>If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] </span>

<span>If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons </span>

<span>A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine </span>

<span>1 proton 1 electron <----- that is considered to be neutral </span>

<span>3 protons, 3 electrons <----- neutral </span>

<span>5 protons 5 electrons <----- neutral </span>

<span>6 protons, 5 electrons <-- positive ion [more protons than electrons] </span>

<span>5 protons, 8 electrons <--- negative ion [more electrons than protons] </span>
