The following mRNA sequence is taken from the middle of exon 3 in a mature mRNA that has many exons, and the mRNA encode 9 amino acids.
Question: Knowing that this mRNA does not have an early stop codon, which of the reading frames shown is the correct one for this mRNA? Write down 1, 2, or 3 as your answer. Explain why?
Homework Answers
3rd frame is correct,
because reading starts from 3' side in mRNA.
all neuclease activity and reading stsrts from 3'side as during translation ribosome starts protien formation by encoding mRNA with the help of tRNA from 3' side

Hemoglobin is a protein that is found in red blood cells. It binds to oxygen in the lungs and it carries it to tissues and cells throughout the body. Hemoglobin is made of four polypeptide chains, two called “alpha-globins” (a) and two “beta-globins" (B). The B-globin polypeptide is produced in the cells based on the sequence of the HBB gene. The structure of the HBB gene that codes for beta-globin is represented below. The primary transcript is 1606 nucleotides long....

Original DNA & mRNA: DNA template: 3' - GGGTACGGCTCTAAA(300b)TACCCGATCGTA - 5' mRNA: 5' - CCCAUGCCGAGAUUU(300b)AUGGGCUAGCAU - 3' What effect would the following DNA mutation have on the polypeptide synthesized from the gene? DNA template: 3' - GGGTTCGGCTCTAAA(300b)TACCCGATCGTA - 5' mRNA: 5' - CCCAAGCCGAGAUUU(300b)AUGGGCUAGCAU - 3' There will be no effect because the codon still calls for the same amino acid. The polypeptide's synthesis will stop too soon because a stop codon has been introduced too early in the sequence. A...

Dystrophin is a protein that forms part of a vital protein complex that connects the cytoskeleton of a muscle fiber cell to the extracellular matrix. This connection strengthens and shapes the muscle fibers. Dystrophin is coded by the DMD gene. This is one of the longest human genes known, covering 2,300,000 base pairs (0.08% of the human genome) It is located in chromosome 21. The immature mRNA is 2,100,000 bases long and takes 16 hours to transcribe. It contains 79...
