The direction of protein synthesis is from amino or N terminus
to carboxy or C terminus. Since the fourth codon is GGG which codes
for glycine, so the fourth amino acid from the N-terminus is
glycine.
Option B is correct
Option A is wrong ( GGG is at fourth position from the N-terminus not at the third position).
Option C is wrong ( Direction of protein synthesis is from N terminus to C terminus).
Option D is wrong (Position of GGG is fourth from the N terminus not from the C terminus).
why the answer is B d start codon in groups of three bases Answer 3. The...

5.1 the underlined bold TAC is an ATG on the other strand. Is this a start codon? why? 5.2. does the underlined bold ATG open an ORF? why? 5.3 which ATG seems to be a valid start codon? Copy the sequence into the answer box and make the start codon bold and underlined. Split the ORF portion into codons fone blank between codons, like this ATG CCC GGG.... Keep the font Courier to keep all symbols equal width. If the copying process...

May S Tae suumissis hot be accepted. 1. (10 points) A series of tRNAs have the anticodon sequences shown below Considering wobble, use Figure 13.12 to determine the possible codons with which each tRNA could pair Posible codons (Indicate the s end of each codon) Anticodon sequence 5-ACG-3 5'-xm UmGG-3 5'-IGA-3' Indicate which amino acid would be covalently bonded to tRNAs with the anticodon sequences given above.

Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
3. What are the “translator” molecules that recognize a codon in the mRNA and deliver the correct amino acid? 6. If each amino acid was encoded by a single codon, what is the minimum number of amino-acyl tRNA synthetases required for translation? 7. Looking at the codon table, if there was a unique aminoacyl-tRNA synthetase required for each anticodon, what is the minimum required? 9. If an aminoacyl-tRNA synthetase recognized any nucleotide (purine or pyrimidine) in the 5’end of the anticodon,...
Translation: find the start codon AUG on the mRNA below, underline nucleotides in sets of three (codons), find the appropriate amino acid for each codon in the chart below, and stop when you come to a stop codon.

Protection from cytosolic enzymes. What is the function of the 5' cap in eukaryotic mRNA? Select one: O a. Polyadenylation of the 5' end of the mRNA. b. Intron splicing signal. O c. It must be on the mRNA in order for the mature mRNA to be exported...
Which of the following is not an essential function of ribosomes in all domains of life? A. Catalyze peptide bond formation between amino acids during polypeptide formation. B. Bind messenger RNA and identify the start codon where translation begins. C. Facilitate the complementary base pairing of mRNA codons and tRNA anticodons that determines amino acid order in the polypeptide. D. Align the Shine Delgarno sequence in the mRNA with a complementary sequence in the 16S rRNA of the small ribosomal...
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...
