Question

How many overlapping trinucleotide units can be obtained for a dna sequence of length 12 nucleotides?

Answer 1

simply the complementary sequence except that uracil complements adenine in the transcripts.  

A=T; which becomes A=U  

G =_ C REMAINS THE SAME

Answer 2

There can be 10 overlapping trinucleotide units that can be obtained for a DNA sequence of length 12 nucleotides.

• The nucleotide trio that  e n c o d e an amino acid is known as a codon. Each gathering of three nucleotides  e n c o d e  one amino acid.
• Since there are 64 blends of 4 nucleotides taken three all at once and just 20 amino acids, the  c o d e  is degenerate (more than one codon for each amino acid, much of the time).

• The connector atom for interpretation is tRNA.
• A charged tRNA has an amino acid toward one side, and at the opposite end it has an anticodon for matching a codon in the mRNA; ie. it "communicates in the language" of nucleic acids toward one side and the "language" of proteins at the opposite end.
• The hardware for blending proteins under the bearing of format mRNA is the ribosome.
