A codon is a sequence of three nucleotides in DNA or RNA that code for an amino acid. This triplet combination is made up of any of the four nitrogenous bases, which are adenine (A), guanine (G), cytosine (C), Thymine (T) in DNA or uracil (U) in RNA. There are 64 codons and...
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...
what is the relationship between DNA, RNA, protein and phenotype?5. what are the stop codons? what is the start codon? do any of these code for amino acids?6. what are the three modifications made to pre-mRNA molecules before they become mature mRNAs ready to be used in protein ...
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...
Genetic code is a set of instructions for transferring genetic data stored in DNA or RNA into proteins. In DNA, the genetic code...
DNA Replication: DNA replication is an important process that occurs as the cell is beginning to divide into two. This is because the new daughter cell will need its own DNA, and so the original DNA needs to replicate. Answer and Explanation: ...
The ATG start codon is also generally observed in the 12 other Anseriform species, including 2 Anser species, with sequenced mitochondrial genomes. TAA is the most frequent stop codon, one of three鈥揟AA, TAG, and T- 鈥揷ommonly observed in Anseriformes. All tRNAs could be folded into ...
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,
is thatnonsenseis resulting from the substitution of a nucleotide in a sense codon, causing it to become a stop codon (not coding for an amino-acid) whilecoois cool. As an interjectioncoois expression of fright, surprise, approval, etc. ...
