Question

A DNA sequence that reads TAC CCC GAA will code for a protein with what ammo acid sequence? A. Met-Pro-Glu B. Tyr-Pro-Glu C. Tyr-Gly-Lcu D. Met-G I y-Leu E. Met-Pro-Lcu If the sequence on at RNA is UAC. then the sequence on the mRNA is: A. AUG B. UAC C.ATG D. CAUWhat happens at the "P" site on the ribosome? A. A peptide bond is formedB. A protein is released C. The ribosome prepares for translation D. There is no "P" site on the nbosomc The 5'cnd of RNA contains a(n):A. 5' G-cap B. 5* poly-A tail C. Intron D. ExonT his codon tells the ribosome to begin translation: A. Begin codon B. Start codon C. Go codon D Promoter codonA codon consists of how many nucleotides A. I B. 2 C. 3 D. 4 E. 5The secondary structure examines which of the following features of a protein:A. The 3-D structureB. The protein-protein interactions C. The amino acid sequenceD. The alpha helix and beta sheet structures The 3' end of RNA contains a(n):A. 3' G-cap B. 3' poly-A tail C. Intron D. ExonMethionine only has I codon: A. True B False If an mRNA strand has the sequence 5'-AUGAUUGUAUGA-3'. what will the amino acid sequence of the protein be? A. Val-llc-Mct-STOPB. Tyr-STOP-His-ThrC. Mct-Val-llc-STOPD. Met-llc-Val-STOPE. Mct-IIc-Tyr-STOP Splicing of RNA removes all: A. Introns B. Exons C. DNA D. Anticodons Nucclcotidcs that arc adjacent (next to) one another form which type of Kinds? A. Phosphodicster Bonds B. Hydrogen Bonds

Explanation / Answer

Adenine and guanine-purines,

Cytosine, thymine, and uracil -pyrimidines.

GENETIC CODE : the codon is triplet. 61 codons code for amaino acids and 3 codons do not code for any amino acids,hence they function as stop codon.

25). TAC CCC GAA

      AUG GGG CUU--met-Gly-Leu

Answer: D
