The preference that different organisms show for one of the several codons that encode a particular amino acid. Translationally optimal codons are those that are recognized by abundant tRNAs. Within a phylogenetic group, the frequency of particular codons in a gene is highly correlated with higher ...
How are phenotype driven by DNA (inheritance in offspring)? True or false? Linked genes are likely to be close together on the same chromosome. One of your friends has several brothers and sisters, each quite different in appearance, interests, and abilities, even though all have the same p...
In this study, we present a whole-genome sequencing methodology capable of sequencing the four genetic letters in addition to 5mC and 5hmC to provide an accurate six-letter digital readout in a single workflow. The processing of the DNA sample is entirely enzymatic and avoids the DNA degradati...
Organisms differ from one another because their respective DNA molecules have different nucleotide sequences and, consequently, carry different biological messages. 生物体不同于另一个因为各自的DNA分子有不同的核苷酸序列,因此,携带不同的生物信息。 But how is the nucleotide alphabet used to make messages,...
But here's the catch: our semisynthetic organisms in order to survive, need to be fed the chemical precursors of X and Y. 但关键是:我们的半合成生物为了存活,需要喂食X和Y两种化学前体细胞。 X and Y are completely different than anything that exists in nature. X和Y与自然界其他东西完全不同。

organisms, except for the unicellular eukaryotes such as yeast, flagellates, ciliates, etc. Therefore, DNA replication in eukaryotes is a highly regulated process and usually requires extracellular signals to coordinate the specialized cell divisions in different tissues of multicellular organisms. External...
Therefore, the information that we can extract from the fasta headers (Protocol 1) needs to be taken in context with the tool used for the prediction. It is possible that different tools predict similar consensus families but classify them differently. Also note that the reliability of homology-...
Synthetic DNA is a growing alternative to electronic-based technologies in fields such as data storage, product tagging, or signal processing. Its value lies in its characteristic attributes, namely Watson-Crick base pairing, array synthesis, sequencing,
The bases that carry the genetic code are tucked safely in the interior of double-helical B-form DNA, protecting them from damage. This hereditary information needs to be constantly accessed in living cells, thereby necessitating DNA supercoiling. Organisms have evolved DNA supercoiling to toggle ...
