Homework Answers
Option 4
Messenger RNA (mRNA) is translated into protein and transfer RNA (tRNA) and the ribosome also participates in the translation reaction.
Option 1
Microarrays can also be used to study the expression of certain genes.

Put the following steps of gene silencing by small interfering RNAs in the correct order: microRNA is folded and processed in the nucleus RISC binds to an mRNA molecule with bases complementary to the guide strand microRNA is transported into the cytoplasm microRNA is transcribed Argonaute protein selects one strand to act as the guide strand mRNA transcription is inhibited DICER cuts the microRNA into short segments (~21 nucleotides long)

Multiple RNA molecules are important in translation: mRNA, tRNA, and rRNA. Which of the following is most likely to slow the production of a single protein in the cytoplasm? Downregulation of genes encoding tRNA components. An increase in the synthesis of the 80S ribosomal proteins important in ribosomal translational initiation. Recruitment of RBPs that promote RNAse degradation to the 3’UTR of the mRNA transcript. Mutations in mitochondrial tRNAs important in the synthesis of mitochondrial proteins.

Which of the following is a chemical or structural characteristic of RNA? The RNA sugar is ribose, which has an OH group on the 2' carbon. O RNA is usually a single-stranded molecule. The bases in RNA include uracil instead of thymine. RNA molecules are generally shorter in length compared DNA macromolecules. All of the above are either a chemical or structural characteristic of RNA. Which of these sequences could form a hairpin? 5' GGGGTTTTCCCC 3' 5' AAAAAAAAAAAA 3' 5'...

Part 1. Eukaryotes use at least two distinct mechanisms to control gene expression by altering the structure of chromatin around a particular gene. One of these mechanisms is the covalent modification of histones to switch DNA between an open and closed confirmation. A second mechanism is the covalent modification of DNA (typically on cytosines) by methylation. A. Describe a type of histone modification and explain what effect is has on chromatin, and how that effect is achieved. a. One type...
