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.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
