What is a complementary mRNA codon?Codon:An array of nucleotides that is constituted by three nucleotides and is accountable for specifying a particular amino acid is called a codon. These sequences are present on the chains of ribonucleic acids and deoxyribonucleic acids and are mostly constituted...
(d) How is information integration at gene regulatory sequences achieved? Genes Genes are units of DNA that serve as discrete pieces of information from the cell, which information can be used to create a cert...
The triple nitrogenous base sequence on mRNA (which is produced from DNA through transcription) is called a codon. Whereas, genetic code refers to sequences of triplet nitrogenous bases or the entire sequence of nitrogenous bases in aDNAsegment. So,genetic code is the language of DNA. ADVERTISEM...
A stop codon is genetic signal that tells mRNA to stop producing a protein. Without a stop codon in place, proteins made from RNA...
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...
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,
a string of three key bases on 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...
What is an example of silent mutation? Silent mutations are base substitutions that result in no change of the amino acid or amino acid functionality when the altered messenger RNA (mRNA) is translated. For example, if thecodon AAA is altered to become AAG, the same amino acid – lysine –...
What does it mean when a DNA strand is complementary? What DNA base is complementary to thymine? What is the complementary RNA strand for adenine (A)? for uracil (U)? for guanine (G)? for cytosine (C)? What is genomic imprinting? What is a complementary mRNA codon? What is the compl...
