<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>
Answer:
Over the past century, American farming has changed dramatically. Crops with long histories like tobacco are still prevalent throughout the South, while many farmers across the country are now exploring the possibility of a thriving hemp market. Every state has a rich farming history, from the tomatoes made in New Jersey, to the sheep used for wool production in Wyoming. Currently, some farms are looking to new technology to maintain their blue-collar livelihood, while others have decided to shut down shop, unable to keep up with fluctuating markets, export worries, and other daily concerns of America’s farmers. Those aspects and more are detailed in Stacker’s dive into how American farming over the past 100 years.
Stacker compiled a list comparing agriculture in each state over the last 100 years using data from the 1920 Agriculture Census, and most recent data as of Feb. 28, 2020, from the 2019 Census State Agriculture Summaries. The 1920 Census figures were released in 1922, and even include some data for areas of the U.S. that weren’t even technically states yet, like Alaska and Hawaii (where bees were widely harvested to make honey and waxes).
While American farming has certainly expanded and increased its value since 1920, there were almost three times as many farms 100 years ago than there are today—in 1920 there were 6.5 million farms, while 2020 estimates come in at two million. Within each slide, we discuss the essence of a state’s agricultural economy then and now, significant changes in crops, legislation, and industry size, and other tidbits like where some of the earliest immigrant farmers arrived from. From Austrians in Delaware to Japanese farmers in Oregon, agricultural workers from around the world helped shape modern American farming.
