List 4 targets of antibiotics.

Biology
1 answer:
Aleksandr-060686 [28]3 years ago
3 0

Answer: Antibiotics targets the synthesis of protein, nucleic acid, folate and cell wall.

1. Synthesis of protein; antibiotics binds to either 30s or 50s ribosomal subunits blocking the polypeptide from the exiting the tunnel thus inhibiting a full completion of protein expression or production.

2. Nucleic acid synthesis; Antibiotics also act by inhibiting genetic expression, DNA transcription and replication where DNA makes exact copies of itself, as well as RNA molecules preventing bacterial growth.

3. Cell wall synthesis; Inhibition of cell wall synthesis in microorganisms will prevent it from replication and growth.

4. Folate synthesis; Folic acid also known as vitamin B9 helps in DNA replication and cell division. Folate antagonists such as aminopterin kills bacteria by preventing folic acid production required for DNA replication.

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.

The letter X in the diagram below represents what enzyme used in the process shown?
Anvisha [2.4K]

<u>Answer</u>: Option D. RNA polymerase.

<u>Explanation</u>:

  • Transcription is the process which is used to produce RNA from a DNA template.
  • The enzyme involved in the process of transcription is <em>RNA</em> <em>polymerase</em> which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
  • RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
  • The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
