Transfer of newly created plasmids to e coli. The bacteria that contains a plasmid with antibiotic resistance will grow in the presence of antibiotic concludes that the insertion was successful.
<h3>
<u>Explanation:</u></h3>
The plasmid DNA that contains the foreign DNA when integrated with the competent bacteria which is e coli and heated, plasmid DNA will be entering into the bacteria by means of some smaller pores that are created in the membranes of the cell.
The plasmid DNA will be copied many times with the help of the replicating mechanism of DNA of the bacteria. Bacteria will grow on a nutrient rich food called agar after the transformation process. Those bacteria that contains a plasmid containing antibiotic resistance only grow in the antibiotic presence. Transformed bacteria will then grow in larger quantity.
The answer is

Karyotypes are diagrams of one’s chromosomes that are used to diagnose chromosomal disorders in developing humans
Answer:
animals and plants
Explanation:
Fossils are remains or traces of animals, plants or other living things preserved in rocks, sediment, ice or amber. They are preserved as molds of the body or parts thereof, as well as tracks and footprints. Fossils and their presence in rock formations and sedimentary layers are known as the fossil record.
The fossil is covered by layers of sediment, which slowly compress until they become, after centuries or millennia, into rocks. The time required to build all this is millions of years and the oldest rocks are below. Often lower fossils are older than higher fossils. For example, if trilobites are found in the deepest layers, since they are more primitive beings; whereas plants and animals are found in the shallower layers.
Answer:
10%
Explanation:
The distance between the given two loci is 20 mu. This means that the recombination frequency between these two loci is 20% and the heterozygote will form 20% recombinant gametes and rest 80% parental type gametes. Therefore, the heterozygous woman AB/ab will form a total of 20% recombinant gametes. The proportion of each recombinant gamete will be 20/2= 10%.
Gametes formed by the woman= 10% Ab, 10% aB, 40% AB, and 40% ab
Gametes formed by the man= All ab (since the man is homozygous for both loci).
Therefore, proportion of Ab/ab genotype= 10% Ab (female gamete) x ab (male gamete)= 10% Ab/ab
