Why siRNA phenomenon is utilized in cell biology? Because specific gene silencing leads to blocking protein translation Because specific gene silencing leads to blocking mRNA transcription Because specific gene silencing leads to blocking DNA replication All answers are correct
Which of the following processes regulates the maturation of mRNA from hnRNA (in the control of gene expression in humans and other eukaryotes)? translation of polypeptides self-replication of DNA processing of RNA transcription of RNA self-replication of RNA
Put the following events involved with protein synthesis in order. Move first event to the top of the list and finishe with the last event. The anticodon of the second tRNA binds at the A site; peptidyl transferase catalyzes a reaction to join the two amino acids together. The stop codon is reached on the mRNA; no tRNA binds, the ribosomes and polypeptide are released. Ribonucleotides are added by RNA polymerase creating a single strand of mRNA. ⠀ The DNA double helix is unwound beginning at the promoter sequence. A 5' cap and 3' poly A tail are added to the mRNA The polypeptide undergoes folding and further modifications, if needed. The ribosome shifts one codon down, opening up its A site. The next tRNA binds. The larger ribosomal unit clamps down on the tRNA carrying MET. The mRNA leaves the nucleus. The 5' cap binds to the small ribosomal unit, leading to the exposure of the start codon; the first tRNA carrying MET binds. :: #10 #
Hydrogen bonds are important in DNA replication and transcription. They are relatively weak chemical bonds. Why is this a desirable feature for DNA? Describe the effect (s) of changing (mutating) the promoter on the transcription of the DNA strand/gene the promoter controls. What happens to protein synthesis if a nonsense codon is inserted into the gene? Explain why a point mutation does not necessarily change the original amino acid sequence. (Explain silent mutations) Choose any pentapeptide composed of five different amino acids. List the amino acids. Present one messenger RNA codon for each amino acids and the sequence of nucleotides on the DNA that originally coded for your pentapeptide.
During transcription, an mRNA molecule is formed: *( Choose True if the statement is correct abourt During transcription, an mRNA molecule is formed: * and False if otherwise ) that it is double-stranded inside the nucleus that is complementary to both strands of DNA that is identical to part of a single strand of DNA
Which is NOT a true difference between messenger RNA and DNA? (i.e., which of the following statements is false?) DNA remains in the nucleus (except when the nuclear envelope breaks down during mitosis), whereas mRNA is never in the nucleus; it is always in the cytoplasm. A DNA molecule has a longer life span than a typical molecule of RNA. DNA has thousands of genes; mRNA is usually a copy of just one gene. DNA has thousands of genes; mRNA is usually a copy of just one gene.

Occurring in the nucleus ribosome mitochondrion , translation transcription is the process of making an RNA copy from a DNA template. The molecule then enters the cytoplasm. The process in which the mRNA sequence is converted into a sequence of amino acids is called translation transcription . In the cytoplasm, the nucleus ribosome mitochondrion reads the amino acid sequence and assembles the protein.
