Concept explainers
(a)
Interpretation:
For the given DNA template strand, 5’-ATCTACCGTTA-3’, the sequence for the mRNA molecule needs to be determined.
Concept introduction:
mRNA sequence is the coding of genes as well as an amino acid. In transcription and replication, this sequence is used.
(b)
Interpretation:
For the given mRNA base sequence 5’-UUGCCUAGUGAUUGGAUG-3’ by assuming reading fame starts from 5’ end. The amino acid sequence that can be formed needs to be determined.
Concept introduction:
mRNA sequence can be determined based on Condon chart.
(c)
Interpretation:
The sequence of the polypeptide formed due to the addition of poly (UUAC) to a cell-free protein-synthesizing system needs to be determined.
Concept introduction:
The sequence of the protein can be given by DNA which encodes a protein and also change in DNA sequence will change the amino acid sequence of proteins.

- Biochemistry Question.For the metabolism of amino acids what is the first step for theirbreakdown? Why is it necessary for this breakdown product to be transported to the liver? For the catabolism of the carbon backbone of these amino acids, there are 7 entry points into the “standard” metabolic pathways. List these 7 entry points and which amino acids are metabolized to these entry points. Please help. Thank you!arrow_forwardBiochemistry Question. Please help. Thank you. You are studying pyruvate utilization in mammals for ATP production under aerobic conditions and have synthesized pyruvate with Carbon #1 labelled with radioactive C14. After only one complete cycle of the TCA cycle, which of the TCA cycle intermediates would be labeled with C14? Explain your answer. Interestingly, you find C14 being excreted in the urine. How does it get there?arrow_forwardBiochemistry question. Please help with.

For clarity only limited atom numbers are shown, but the main chain carbons are numbered 1 to 16, and the off-chain methyl substituents are numbered 17-20. A. Based on what you specified in A, use curly arrows on the drawing above to convert 5 to 6, and 6 to 7. Invoke general acids and general bases as needed, and draw in hydrogens as necessary . B.

The peptide bond is non-polar, hydrophobic and does not have a dipole. The peptide bond is most stable in the cis configuration. The peptide bond is rigid and planar. The peptide bond has a mix of single and double bond characters. The peptide bond is most stable in the trans configuration.arrow_forward
