A mutation that changes a C to a T causes a type of Ehlers-Danlos syndrome, forming a “stop” codon and resulting in shortened procollagen. Consult the genetic code and suggest one way that this can happen.
Transcribe the DNA strand given above to write the sequence of the mRNA strand in the 5’ to 3’ direction.
Use the table and write the sequence of the resulting peptide.
Is it possible for a codon to code for another amino acid?
What will be the effect if a mutation changes the codon UAU to UAA?
What is a reading frame?
If you are given a nucleotide sequence, how would you find Open Reading Frames?
DISCUSS the reason why there are leading and lagging strands in replication?

code. What is a human
condition caused by these
mutations? Identify how the
reading frame is affected.

- Consider this nucleotide sequence of DNA strand in the image provided. If this strand is the sense strand, Give the correct nucleotide sequence of the RNA produced after transcription. If the RNA formed in #1 is already a functional mRNA and will be used to synthesize proteins, how many codons are present here that will actually code for amino acids?

You do not need to memorize the code, except for the start codon (AUG = Met) and the stop codons (UAA, UAG, UGA). Which of the following statements about the genetic code is correct? A) All codons specify more than one amino acid. B) The genetic code is redundant. C) All amino acids are specified by more than one codon.

Use the mRNA codon chart in the Appendix of your manual to help you. Answer: Checkarrow_forwardA certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forward
- Now we need to know which amino acid the tRNA is carrying. We can do this on paper using the GeneticDictionary below. Starting with the 1st base in the codon, pick the row. Then use the 2nd to pick the column,the use the 3rd to pick the line. There you will find an abbreviation of the name of the amino acid (AA).Write that abbreviation in the AA (short) box next to the appropriate anti-codon. Use the list below tofind the full name of the amino acid and list that in the AA (full name) box. Remember to translate themRNA codons and not tRNA!Notice that there is only one START codon and a few STOP codons. Go ahead and finish the strand evenif it doesn’t start with Met. Why do you think there is only one START? Why do you think there might be more than one STOP?GENETIC DICTIONARY U C A G U Phe Phe Leu Leu Ser Ser Ser Ser Tyr Tyr STOP STOP Cys Cys Stop Trp U C A G C Leu Leu Leu Leu Pro Pro Pro Pro His His Gln Gln Arg Arg Arg Arg U C A G A Ile Ile Ile…arrow_forwardA codon that specifies the amino acid Gly undergoes a single-base substitution to become a nonsense mutation.
