近年来不少城市积累了资金、习得专长的农民工，开始逆向流动，返乡创业，这类人，被媒体称之为“城归”。据统计，近年来“城归”人数累计达到450万，随着党的十九大明确提出乡村振兴战略的实施，将有更多的“城归”返乡创业，这给乡村带来了人口红利升级，促进家乡的社会经济发展。 根据以上材料，作答53—55题...
A codon is a triplet sequence of RNA bases that code for a specific amino acid. The anticodon contains complementary bases to the codon. This allows the anticodon to base pair with the codon. Each anticodon has a specific amino acid attached to it. This is how the pol...
What is a codon? What is an anticodon? How do they differ? tRNA tRNAs (transfer RNAs) are sequences of RNAs that are critical in the synthesis of proteins by ribosomes. tRNAs will have one amino acid attached to them, which will be used in the synthesis of a polypeptide. There...
what is the function of each modification?7.briefly describe the function of the following in protein synthesis:rRNA,tRNA,and mRNA.8.Write the anticodons for the following amino acids:met,ser,leu,trp9.given the following tRNA anticodon sequence,derive the mRNA and the DNA template strand.also...
transcription always proceeds in the 5'->3' direction the codon under the reading frame is matched with a specific tRNA containing a specific amino acid the start codon always encodes the amino acid Methionine. the new amino acid is attached to the growing protein the frame then advances 3 ...
Codon will always be in triplet form as it is coding for a single amino acid. So,it is a triplet that is known as a codon. It is a set of instructions that directs the translation of DNA into amino acids, the monomers of proteins. As a codon is a group of three nucleotides, the...
the tRNA, match with three bases on the mRNA message called the codon. That is only the first function of tRNA, as each molecule also carries with it an amino acid which matches the mRNA codon. The ribosome functions to polymerize the amino acids linked to the tRNA into a functional ...
The degeneracy of the code means a codon whose nitrogenous base composition is different from another codon could yield the same amino acid. For instance,
How are the somatic nervous system and the autonomic nervous system different? What is the difference between an anticodon and a codon in the tRNA? What is hemochromatosis? How is it caused? What is the difference between concave and convex mirrors?
translation, a strand of mRNA passes through a ribosome, like an old-fashion cassette tape moving through a tape reader. As the mRNA moves through, tRNA molecules carrying the appropriate amino acid bind to the RNA codon to which they are matched, and the sequence of amino acids is put ...
