Answer:
Some bacteria due to their structures and physiology are inherently resistant to some antibiotics. This could be due to lacking transport mechanism or lacking receptor sites. Bacterium develop resistance mechanisms by using instructions provided by their DNA. Resistance genes are often found in plasmids which are small pieces of DNA that carry genetic instructions from one germ to another. Meaning that some bacteria can share their DNA and cam make other germs become resistant.
I hope this can help you and that it was clear.
Apologies if it wasn't
Atom, cell, tissue, organ
Explanation:
Like all enzymes, a restriction enzyme works by shape-to-shape matching. When it comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the DNA molecule.
A. because prkaryotic cell dont have a nuclues and the eukaryotic cells do
Explanation:
Assuming the allele for Red color is <u><em>R</em></u> and that for white is <em><u>r</u></em>, and that for Tall is <em><u>T</u></em> and short is <u><em>t.</em></u> Using Mendelian principle of independent assortment, the alleles will combine as shown in the attached Punnet Square;
All the offspring will have the phenotype of Red roses and Tall. The genotype, however, will be RrTT : RrTt in the ratio of 1 : 1
