Replication: DNA into DNA, and RNA primer are required;Transcription/RNA processing: pre mRNA and then mRNA;Translation: tRNA, rRNA

Explanation:

1. During replication, a semi-conservative copy of a DNA molecule is made with the help of various enzymes and RNA primer.

2. Transcription/RNA processing: mRNA

During transcription, the DNA "message" ( in the form of codon) is copied into mRNA.

3. Translation: tRNA, rRNA

During translation, the information carried in the mRNA is translated into protein with the help of molecules of tRNA and rRAN to build a protein on the ribosomes.

Role of RNA

Explanation:

Replication-Transcription-Translation process:

In case of prokaryotes a single type of RNA Polymerase synthesizes all types of RNA (mRNA, rRNA and tRNA) whereas in case of eukaryotes three different types of RNA Polymerase synthesize different types of RNARNA Polymerase I transcribe all types of rRNA except 5S rRNARNA Polymerase II transcribe all types of mRNA and most of snRNA and miRNARNA Polymerase III transcribe all types of tRNA, 5S rRNADuring the process of transcription ( DNA to mRNA) mRNA is synthesized which carries the genetic information from DNA rRNA is required for the synthesis of ribosomes, ribosomes are ribonucleoprotein complex that actively participate in protein synthesis and found in all living cellsA functional ribosome consists of two subunits:Smaller subunit decode genetic information present in mRNA whereas large subunit has peptidyl transferase activity; in bacteria peptidyl transferase activity present in 23S rRNA while in eukaryotes present in 28S rRNA Small and large subunit of ribosomes are associated to each other during translation initiation whereas essentially dissociate during translation terminationtRNA are small (75-95 nucleotide long) in eukaryotes transcribed by RNA Polymerase III, function of tRNA includes transfer of activated amino acid from cytoplasm to the active site of ribosomes

"a.) well–developed vascular system."

Answer from: Quest

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

Cold case files recently began re-investigating an old murder case. the murder took place in the park; a young man, james, was hit over the head with a brick and killed. police suspected the jealous former boyfriend of james' wife, karen. whoever killed james may have washed their hands in a near-by bird bath as detectives found blood in the bird bath. since the murder took place before dna fingerprinting was available, the suspected killer, ronnie, went free. detectives are now reviewing the blood evidence using dna fingerprinting. based on the dna fingerprints of all possible suspects, who is james' killer?
