Answer: Transfer RNAs are coded by a number of genes, and are usually short molecules, between 70-90 nucleotides (5 nm) in length. The two most important parts of a tRNA are its anticodon and the terminal 3’ hydroxyl group, which can form an ester linkage with an amino acid.
Explanation:
Prokaryotes are usually smaller than eukaryotes. They also don’t have a nucleus so DNA is in the cytoplasm. They also have no organelle membranes where as eukaryotes do. Domains of prokaryotes include Bacteria and Archaea, and all eukaryotes are in the domain Eukarya. Both can be free living, but only eukaryotes can be multicellular. Prokaryotes first appeared on earth about 3.5 billions then eukaryotes appeared about a billion years later. Etc....
Answer:
To carry both of the genes for an allele, the organism must have the homologous chromosomes. Each homologous chromosome will carry one allele for the gene. In males, there is only one X chromosome and one Y chromosome. In females, there are two X chromosomes. Hence, males will carry only one allele for the genes which are present on the X chromosome. On the other hand, females will have both the alleles as they have two X chromosomes.
