Information transmitted by mRNA needs to be short-lived so that the cell can maintain regulatory checks and balances. On the other hand, the structure of DNA must be stable. How does the difference in structure make mRNA less stable than DNA? base base O-P-0- NH о-Р-о- NH 4' 3' 2 4' 3' 2 OH base H base NH NH о-Р-о- || о-Р-О- || OH RNA DNA

Question 6: Determine the sequence of amino acids specified by the codons in the following information strand. AGG TCT TCA GGG AAT GCC TGG CGA GAG GGG AGC AGC TGG TAT CGC TGG GCC CAA Then determine the sequence of amino acids if an insertion occurred to the left of the first adenosine and changed the reading frame as shown below. Notice that (1) the insertion is shown on the left by the lower-case “i”, and (2) the bases are still in the same sequence; they are just shifted so that they are read differently. iAG GTC TTC AGG GAA TGC CTG GCG AGA GGG GAG CAG CTG GTA TCG CTG GGC CCA…

"Unlike what happens in DNA replication, where both strands are copied, only one of the two strands is transcribed into mRNA. The DNA strand that contains the gene is sometimes called the sense strand, or coding strand, and the DNA strand that gets transcribed to give RNA is called the antisense strand, or noncoding strand. Because the sense strand and the antisense strand are complementary, and because the DNA antisense strand and the newly formed RNA strand are also complementary, the RNA molecule produced during transcription is a copy of the DNA sense strand... The only difference is that the RNA molecule has a U everywhere the DNA sense strand has a T." Consider the following segment of a DNA sense strand: (5') CAA-ACT-ACG-GCG-TTG-CAG (3') (a) Determine the base sequence in the antisense (non-coding) strand. Be sure to specify which end is 5' and which is 3'. (b) Determine the base sequence in the messenger RNA strand. Be sure to specify which end is 5' and which is 3'.
