Question
Chapter 12, Problem 9CONQ
Summary Introduction
To review:
The RNA (ribonucleic acid) polymerase subunit and its composition. And, the different roles of subunits present in RNA.
Introduction:
The DNA (deoxyribonucleic acid) sequences consist of a few functional promoters. The RNA strand is formed after transcription and this strand consists of many enzymes which help it to bind to the DNA. This helps the RNA strand in creating the protein sequence. The amino acids join to the strand of mRNA.

- What is the properties of ribonuclease enzyme and describe what reaction it catalyzes?arrow_forwardConsider the following tRNAs, where the numbered forms represent the amino acids associated with them, answer briefly: PICTURE Question 1: The numbering indicates the order in which these tRNAs are recruited to the A site of the ribosome. Write the sequence of the mRNA being translated in the 5' - 3' direction Question 2: What is the amino acid sequence of the produced polypeptide? Question 3: Researchers discover that a mutation is in the anticodon of the gene encoding the proline tRNA of an individual. The anticodon sequence is normally 3' GGA 5', but in this individual the anticodon sequence is 3' GGG 5'. It appears that this individual suffers no adverse consequences. How can this be?

Briefly explainarrow_forwardWhat enzyme catalyzes protein synthesis in bacteria? You discover a new broad-spectrum antibiotic that inhibits protein synthesis and named it Compound J. You want to determine the mechanism of action of Compound J. After treating bacteria cells with Compound J, you observe many ribosomes with long polypeptide chains bound to them. Based on this observation, make a hypothesis about which part of the ribosome Compound J is binding and how this specifically affects translation. What evidence supports that proper protein folding is essential to all domains of life? Name and describe the function/s of two specific molecules that help proteins fold in bacteria.arrow_forward
