The code for creating amino acids is said to be redundant because some codons code for the same amino acid (i.e. there is redundancy because several codons have the same function).
For example, the RNA codons AAA and AAG both code for the amino acid Lysine. The codons ACU, ACC, ACA and ACG all code for Threonine.
Aspartic acid and Glutamine.
Lysine Threonine Glutamic acid
mRNA
exons - good parts of gene that code for amino acids introns- "junk DNA" that do not code for amino acids of a protein ( before leaving the nucles mRNA must have these removed, then it can travel into the cytoplasm)
Translation
Aspartic acid and Glutamine.
At the Ribosomes.
Lysine Threonine Glutamic acid
mRNA, rRNA, tRNA mRNA transcribes the genetic code and carries it to a ribosome, which is composed of rRNA and proteins, and tRNA carries amino acids to the ribosome where the amino acids are assembled in the correct sequence according to the mRNA code.
An mRNA transcript carries the genetic code to the ribosome. tRNA molecules bring amino acids to the ribosome for translation. The amino acids polymerize into functional proteins.
tRNA brings amino acids to the mRNA on the ribosome.
An amino acid is not mRNA or tRNA. Amino acids are the building blocks of proteins, while mRNA carries the genetic information from DNA to the ribosome to be translated into a protein, and tRNA is responsible for bringing specific amino acids to the ribosome during protein synthesis.
The molecule that fastens amino acids down on the mRNA is transfer RNA, or tRNA.
mRNA
The triplet code on mRNA is known as a codon. This 3-base sequence codes for a specific amino acid to be added to the chain (i.e. protein) being created.
DNA is changed into mRNA. from there, the mRNA goes to a ribosome and is translated into amino acids.
mRNA connects with the subunits of the ribosome. Each codon is read specifically and a matching anticodon brought by a tRNA is transferred. Each matched triplet adds amino acids to the polypeptide chain.
