WebOct 6, 2024 · Why are well-defined reading frames critical in protein synthesis? O A. Without a well-defined reading frame, the ribosome is unable to bind to the mRNA. OB. Without a … An open reading frame (ORF) is a reading frame that has the potential to be transcribed into RNA and translated into protein. It requires a continuous sequence of DNA from a start codon, through a subsequent region which usually has a length that is a multiple of 3 nucleotides, to a stop codon in the same reading frame. When a putative amino acid sequence resulting from the translation of an ORF remained unknow…
Reading frame in protein synthesis
Did you know?
WebAn open reading frame (ORF) is a series of codons that begins with a start codon (usually AUG) and ends with a stop codon. There can be no additional stop codons within that sequence. In genes that lack introns (e.g. most prokaryotic genes), an ORF in the DNA sequence will define the entire translated region. WebMay 22, 2024 · Well-defined reading frames are critical in protein synthesis, because any change in the reading frame would result in a peptide completely different of the one desired. A clear example of the importance of a well-defined reading frame is seen in frameshift mutations, at which nucleotide insertions or deletions causes leads to the …
