Protein Synthesis Payton Sloop


DNA: a double helix shape that stores all genetic information

mRNA: messenger RNA; carries the copied genetic information from DNA

tRNA: transfer RNA; decides which genetic code sequence goes with the correct amino acid

rRNA: ribosomal RNA; assembles amino acids into protein chains.

DNA Replication

Dna is unzipped in the middle by the helicase into 2 separate strands. One strand is read the replicated to make new strands. After this, the nucleotides join together again. This takes place in the nucleus.


Transcription makes a complimentary strand of rnA. mrna carries instructions from the nucleus to cytoplasm tobe arranged in codons.


Once mrna joins a ribosome in the cytoplasm, the nucleotide codons are translated to aminpo acids.
