What is the difference between a coden and an anti coden?
a codon is the sequence of three nucleotides of mRNA, the anti codon is the amino acid of tRNA that is matched to the codon.
What event occurs during the elongation stage?
mRNA passes through ribosomal subunits, tRNA deliver amino acids to the ribosomal binding site in the order specified by the mRNA, & peptide binds forms between the amino acids and the polypeptide chain grows
What role does Trina RNA play in gene expression?
A transfer RNA (tRNA) molecule attaches to a specific amino acid in the cell cytoplasm specific to its anticodon, and takes it to a ribosome where it will pair its anticodon with the complementary mRNA codon and drop off the amino acid, which will be placed into the protein being formed. The tRNA molecule is then free to attach to another amino acid in the cytoplasm. This is called translation because the tRNA translates the mRNA code into amino acids.
What role does the structure of RNA and DNA play in protein synthesis?
mRNA. tRNA,
What is the role in the 3 types of Rna in gene expression?
The central dogma of molecular biology has been: DNA makes RNA; RNA makes proteins. Proteins carry out the bulk of functions involved in running a living organism.
What is the name of the chemical substance that contains the anticodon?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.
What is the order or events in gene expressions?
Transcription > Translation is the order in the expression of a gene. Transcription is like getting the information from something. Translation is like taking that information and build your final product.
What makes the beginning of a new gene on DNA in eukaryotes?
Translation tRNA
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
A single stranded nucleic acid that plays a role in protein synthesis?
RNA. mRNA, tRNA, and rRNA all play parts.
What contains information to produce a single polypeptide?
the gene and mRNA carries it but a ribosome and a tRNA can be used to make any polypeptide
Describr the role of tRNA in translation?
it moves the amino acids into chain
What molecule contain anticodons?
The tRNA gene sequence is the anti-codon while mRNA is the codon sequence.
In an analogy between a factory and a cell if DNA is the superintendent and mrna is the order to the assembly line what might be the role of trna?
tRNA would be the assembly workers.
