Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.
It inhibits the ligation activity.
Antimicrobial agents interfere with either DNA replication cell wall synthesis, plasma membrane integrity, ribosomal function, or folate synthesis. Ciprofloxacin belongs to fluoroquinolones class of antibiotics that interfere with DNA replication. DNA gyrase is a bacterial topoisomerase that cuts and then reseals DNA to change DNA topology during replication. The binding of ciprofloxacin to A subunit of gyrase enzyme stabilizing gyrase–DNA complex. This leads to inhibition the resealing (ligation) activity of the enzyme leaving the DNA fragmented.
