Answer:
1. the F' plasmid.
2. the bacterial chromosome
3. the bacterial chromosome
4. the F' plasmid.
Explanation:
The F' plasmid is an extrachromosomal DNA molecule composed of genes that act during the transference of genetic material. This plasmid can also be defined as an episome capable of transferring itself into another bacterial chromosome. The bacteria that contain F factor are named F+, while bacteria without this factor are called F-. During conjugation, the F+ factor interacts with F- cells to enable DNA transference among bacteria.

A mutagen is a chemical or physical phenomenon, such as ionizing radiation, that promotes errors in DNA replication. Exposure to a mutagen can produce DNA mutations that cause or contribute to diseases such as cancer.

Answer:
A DNA molecule produced by combining DNA from different sources is known as recombinant DNA.
Explanation:
Recombinant DNA (rDNA) can be obtained by coupling DNA fragments from different sources, a process that is performed at the restriction site level and uses enzymes.
Once rDNA has been designed —cutting out fragments of DNA that are then reassembled— it must be brought to a specific location in the cells, to be copied and expressed, using means of transport called vectors.
<u>DNA recombination</u> is performed in biotechnology laboratories specialized in the manipulation of genetic material.
The other options are not correct because:
- <u><em>Mutant or mutated DNA</em></u><em> is a DNA molecule with an alteration of its nitrogenous base sequence
</em>
- <u><em>Hybrid DNA</em></u><em> is a variant of recombiant DNA, in which only two DNA molecules from different sources are used.
</em>
- <u><em>Polyploid</em></u><em> refers to cells containing the genome of different species.</em>
This if as far as I can help you the middle one is heterozygous so the homozygous is recessive not dominant in this trait
