An animal leaves its footprint in wet mud, and later, when the mud dries, the footprint can be filled with plaster. When the plaster hardens, it has same shape as the foot of the animal. The plaster cast could then be used to make new footprints in soft mud identical to those made by the animal. The

process of using the plaster cast to make new footprints most accurately models

translation of mRNA codons to form a protein.

transcription of mRNA from the original DNA code.

insertion of nucleotides into the mRNA codons

deletion of nucleotides from the tRNA anticodons.

The  process of using the plaster cast to make new footprints most accurately models transcription of mRNA from the original DNA code

Explanation:

Transcription is a process in protein synthesis that takes place in the nucleus. During transcription, the DNA of a gene is used as a template to make an RNA molecule. In the process, nucleotide bases which are complementary to  those found in the DNA molecule pairs with the DNA bases in a process called complementary base-pairing. However, Uracil is the nucleotide base that binds to adenine in the mRNA instead of thymine. An enzyme called RNA polymerase II catalyzes the formation of a mRNA molecule. Three steps are involved in transcription:

Initiation- is the beginning of the transcription process when RNA polymerase binds to DNA.

Elongation- addition of nucleotides to the RNA strand.

Termination- is the end of the process whereby RNA strand detaches from DNA template. The resulting mRNA is a single-stranded copy of the gene.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
