<span>tRNA carries a single amino acid to the ribosome.
It fits the codon on the mRNA in the ribosome with it's anti-codon.
The ribosome has peptidyl-transferase activity which catalyses the peptide bond between 2 amino acids on 2 tRNAs in the ribosome.
One tRNA is released and then picks up another amino acid depending on its anti-codon.

Answer:
The correct answer is- Histone
Explanation:
DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.
Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.
DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
Often times, non-human life in an urban ecosystem is more disturbed in a way that changes happen rapidly, such as the soil and plant cover and temperature and water availability
