A strand that is transcribed is called a template strand, the other one is called a coding strand. The template strand is in 3'-5' direction, and the coding strand is in 5'-3' direction. mRNA is transcribed from 3'-5' template DNA strand, so it is in 5' to 3' direction. <span>The first codon of mRNA is called start codon and usually it is AUG.
Knowing this, we can answer the questions:
The transcribed strand must contain three nucleotide sequence complementary to AUG codon. According to the base pairing rules, it must be TAC. The strand that contains TAC, and, thus, is transcribed is </span><span>C C C T A C G C C T T T C A G G T T. This template strand is in 3'-5' direction and the other one is 5'-3'. mRNA transcription begins from the DNA sequence complementary to AUG codon: </span>DNA sequence: 3' C C C T A C G C C T T T C A G G T T 5' <span>mRNA sequence: 5' A U G C G G A A A G U C C A A 3' mRNA sequence is in 5'-3' direction.</span>
Your body needs two key nutrients: calcium and vitamin D. Calcium is the mineral that strengthens bones and teeth, and vitamin D helps the body absorb calcium while improving bone growth. So stuff like <em>yogurt, milk, salmon, tuna, and spinach.</em>
