The following are directly needed for protein synthesis except rrna. a.peptidyl trna. b.mrna. c.amino acyl trna. d.dna

The correct answer will be option-D

Explanation:

The process of protein synthesis from DNA takes place through a process known as the translation which translates the mRNA to the amino acid sequence. The process of translation involves three different types of RNA mainly mRNA, rRNA and tRNA.

The rRNA forms the structural component of the ribosomes which acts as a site for the translation. The mRNA is read by the ribosomal subunits which utilize the aminoacyl tRNA used to attach the amino acids corresponding to the codons. The peptidyl tRNA interferes with the process of the protein elongation.

Thus, option-D is the correct answer.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
