The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and
ivann1987 [24]

The genotypes would be bbTT X BbTt

Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.

Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)

  • The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
  • The genotype of a tree that is heterozygous for both trait would be BbTt
  • Thus, the cross would be bbTT x BbTt

. For the following give the mRNA, tRNA and amino acid (a.a.) sequence that will be created:
alexdok [17]
<span>mRNA: UACAUGGCCUUACGCUAA tRNA: AUG UAC CGG AAU GCG AUU a.a: Tyrosine, Methionine, Alanine, Leucine, and Arginine DNA has 4 different bases, they are Adenine (A), cytosine (C), guanine (G), and Thymine (T). RNA also has 4 bases with three of them being identical to the DNA bases and Thymine being replaced with Uracil (U). These bases are generally represented by the 1st letter of their names. Each of the bases will join with a complementary base, so A always pairs with T or U, and C will pair with G. So to create the mRNA, simply replace every A with a U, every C with a G, every G with a C, and finally, every T with a A. So mRNA: UACAUGGCCUUACGCUAA Now for tRNA, there's a slight twist. It only comes in 3 base codons, You won't find a sequence of tRNA other than in 3 base codons. And each of those codons will be uniquely paired with an amino acid. In the ribosomes, the mRNA will be sequentially scanned 3 bases at a time allowing for a matching tRNA sequence to bind to the exposed 3 bases, this will cause the next amino acid to be bound into the protein being constructed. So split the mRNA into 3 base sequences and calculate the complement to get the tRNA. A simple shortcut is to look at the original DNA sequence and simply replace a T bases with U. So tRNA: AUG UAC CGG AAU GCG AUU Notice the spaces every 3rd base. THIS IS REQUIRED. These is no continuous length of tRNA. You'll only find it in 3 base lengths and each of them will be bound with an amino acid. For the amino acid that's coded to the RNA, you'll need to use a lookup table in your text book, or one you can find online. Then it's a simple matter of matching each 3 base sequence to the amino acid. For the sequence given we have: AUG - Tyrosine UAC - Methionine CGG - Alanine AAU - Leucine GCG - Arginine AUU - STOP Notice the AUU doesn't decode to a specific amino acid. It instead indicates to the ribosome to stop the production of the protein. So the amino acid sequence for the originally given DNA sequence is: Tyrosine, Methionine, Alanine, Leucine, and Arginine.</span>
