The correct answer is:
nucleic acids
Explanation:
Nucleic acids are biopolymers, or humble biomolecules, necessary for all known methods of life. They are formed of nucleotides, which are monomers comprised of three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base..Nucleic acids are the basic unit of heritage, they develop all the genetic element of living things.This genetic information defines how individual cells and entire organisms grow and function
Answer:
The correct answer will be- proteoglycans and the glycoproteins
Explanation:
The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.
The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.
Thus, proteoglycans and glycoproteins are the correct options.
Answer:
The colonies are carrying the resistance genes from plasmids
Explanation:
Bacteria can acquire beneficial characteristics that they didn’t have. One way for these is through plasmids, which ones are little fragments of DNA that usually contains resistance genes (for antibiotics, disinfectants, heavy metals, etc.) or other capacities, like the ability to use some substances (for example sugars).
In this specific situation, we already know that the plasmid carrying genes for tetracycline resistance and the <em>lacZ</em> gene.
A little explanation:
Tetracycline is an antibiotic that inhibits bacterial growth and kills the bacteria. The bacteria can “fight” to this antibiotic if it has a resistant gene, the result is that the antibiotic can’t affect the bacteria and survive. An analogy is like a Police Officer (bacteria) that have a bulletproof vest (tetracycline-resistant gene) so the bullets (tetracycline) didn’t affect the police.
In the case of X-gal, is a compound consisting primarily in one sugar called galactose. Not all bacteria can eat galactose, they need an enzyme called β- galactosidase (comes from <em>lacZ</em> gene) that helps the bacteria “eat” the sugar (cuts the sugar in little pieces so the bacteria can eat).
Then, as the bacterial colonies can grow in the medium with tetracycline and X-gal, we know that those bacteria are carrying the resistance genes for tetracycline (does not affect the bacteria) and the <em>lacZ</em> gene (bacteria produce β- galactosidase that cuts galactose). These genes are coming from the plasmids because we already know that the plasmid carries these genes and not from the exogenous DNA.
