The only base-pairs that are possible are:
Adenine - Uracil (for RNA, since the question refers to codon and anticodon)
Guanine - Cytosine
The reason for this particular base pairing is that it is the only possible combination for the hydrogen bonds between the bases to be effectively made.

ViviThe anticodon is complementary to the codon because of the base pairing rules of DNA and RNA: Adenine (A) pairs with Uracil (U) and Guanine (G) pairs with Cytosine (C). In this case, A in the anticodon pairs with U in the codon, G in the anticodon pairs with C in the codon, and A in the anticodon pairs with U in the codon, making them complementary.

What is the amino acid sequence that is coded for the mRNA sequence AUG-ACG-AAA-AGA-AGG-GGA-GCC-GCU-UCC-UAA?
The mRNA sequence AUG-ACG-AAA-AGA-AGG-GGA-GCC-GCU-UCC-UAA translates to the amino acid sequence Methionine-Threonine-Lysine-Arginine-Arginine-Glycine-Alanine-Leucine-Serine-Stop.
Which three codons would code for a different amino acid sequence from that coded for by the mrna base sequence agu uca cca?
The codons that would code for a different amino acid sequence are AGC, UCU, and CCC. AGC codes for serine, UCU codes for serine, and CCC codes for proline. This changes the amino acid sequence from serine-serine-proline to serine-serine-proline.
What are the four mRNA codons for threonine?
The four mRNA codons for threonine are ACU, ACC, ACA, and ACG. These codons code for the amino acid threonine during protein synthesis.
Mrna has the following condons agu-ggu-cga what would the anticodons be on tRNA?
The anticodons on tRNA corresponding to the mRNA codons would be UCU-CCA-GCU. This is because they are complimentary to the mRNA codons based on the genetic code.
What is the sequence of the peptide based on the mRNA sequence 5'uuuuccuauugucuu3'?
The mRNA sequence provided is "5' UUUUCCUAUUGUCUU 3'". To convert this into a peptide sequence, we need to group the mRNA sequence into codons (3 nucleotides each) first. The codons are UUU, UCC, UAU, UUG, UCU. Using the genetic code, we can translate these codons to the corresponding amino acids, which are Phenylalanine (F), Serine (S), Tyrosine (Y), Leucine (L), and Serine (S). Therefore, the peptide sequence would be FSYLS.
