Relaxed pairing specificities in the third-base position of a codon

Write all possible codons recognized by each of the given anticodons. An anticodon strand reads 5'-UGA-3'. Fill in the missing base sequences for the possible codons recognized by the anticodon. Codon: 5- Codon: 5'- -3' Codon: 5'- -3' An anticodon strand reads 5'-AUU-3'. Fill in the missing base sequences for the possible codons recognized by the anticodon. -3'

The genetic code is Random in that the codons for the same amino acid are structurally unrelated Read by pairing codons in TRNAS with anticodons in mRNAs Read by pairing anticodons in TRNAS with codons in MRNAS Redundant in that each codon can code for multiple amino acids

Sequence most commonly found at the boundary between exon-intron boundaries is            at the 5' end and            at the 3' end     Question 33 options:   G/GU; AG/G   AG/G; G/GU   A/GG; GG/U   All of the above

(ol soupe bannos96 SAM 3 A small strand of DNA has this sequence: 0pxbeter owl nade hoparg TACCGGAAACTG ATGGCCTTTGAC a. If the TOP strand is the template strand, what will be the mRNA made from this DNA read from left to right? What process allows for the mRNA to be made? b. If this is a eukaryotic mRNA, where does transcription occur? What would happen if the mRNA was not processed? c. What is the sequence of the protein made (use the genetic code below)? What process allows for the protein to be made?

3b) In the real world, where "wobble" pairing is possible, what is the minimum number of tRNAs required to service all of the threonine codons? Write out the base sequences of the anticodons of those tRNAs (remember to label the 5' and 3' end of each anticodon sequence).

The purpose of the tRNA in the P site is to: hold the growing polypeptide chain and transfer it to the A site Initiate translation termination stabilize the single strands of DNA
