Why do codons consist of three nucleotides? What converts DNA into mRNA? Which of the following would be problematic when producing a polypeptide? Explain. a. Multiple codons code for the same amino acid. b. One codon codes for multiple amino acids. Which base in an anticodon will pair wit...
Codons: A codon is a sequence of three nucleotides, in DNA or in RNA, that combine to be the genetic code for a given amino acid during translation. Many amino acids can be coded from different codon sequences since there are a total of 64 codons that can be made from the four nucleo...
A frameshift mutation will in generalcause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. What is frameshift mutation How does it affect functio...
However choosing the right RNA code for efficient protein production is less straightforward, more akin to deciding on the pizza toppings. The possibility to choose synonymous codons in the gene sequence has ignited a discussion that dates back 50years: Does synonymous codon use matter? Recent ...
AUG methionine initiating codons are indicated, three inframe AUG codons are present in the uORF preceding the UCP2 coding sequence, so the AUG codon initiating UCP2 translation is the fourth. (B) Translation of UCP2 is impaired by uORF, and ribosomal subunits start scanning the mRNA at its...
To do so base pairs are put into groups of 3, calledcodons. A codon is a sequence of threeDNA bases. Codons are the base unit for one amino acid to be made. However, genetic code has another layer. DNA is then divided into genes. A gene is a section of DNA bases (or codons) ...
Formation of a specific protein is necessary for a cell. What will happen if the mRNA coding for this protein synthesis does not have codons UAA, UGA and UAG ? View Solution Exams IIT JEE NEET UP Board Bihar Board CBSE Free Textbook Solutions ...
In the genetic code, each three nucleotides in a row count as a triplet and code for a single amino acid. How many genetic codes are there? There are 64 possible codons, three of which do not code for amino acids but indicate the end of a protein. The remaining 61 codons specify the...
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 synthesis?what is the function of each modification?7.briefly describe the ...
Termination is initiated by stop codons (UAA, UAG, or UGA) that do not have corresponding tRNAs, but instead signal release factors to put an end to protein synthesis. The polypeptide is sent off, and the two ribosomal subunits separate. ...
