List the order for the production of a protein for export: Protein is processed at the Golgi Apparatus MRNA is translated into amino acid sequence at the ribosome embedded in RER Protein is released from cell via Exocytosis MRNA is transported to the cytoplasm Gene is transcribed into an mRNA molecule within the nucleus
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 #

In the eukaryotic nucleus, synthesis of ribosomal RNA, and the assembly of the large and small ribosomal subunits, takes place in which of the following locations? the outer nuclear membrane the nuclear envelope the nucleolus the nuclear pores the inner nuclear membrane
The genetic code is made of 3 RNA nucleotides read 3'-->5' 3 RNA nucleotides read 5'-->3' 3 DNA nucleotides read 3'-->5' 3 DNA nucleotides read 5->3' An anticodon read by the ribosome The special shape of the Ribosome P-site The special shape of the Ribosome A-site A protein release factor that binds the start codon

Which of the following is the first step of translation in a eukaryotic cell? O a RNA containing activated methionine binds to AUG of the messenger RNA the ribosome reaches a stop codon the small subunit of the ribosome recognizes and attaches to the 5' cap of mRNA O binding of the larger ribosomal subunit to smaller ribosomal subunits
Match the following: Forms part of the subunits for the protein synthesizing organelle A molecule that binds to a specific codon and specific amino acid simultaneously Attaches the correct amino acid to its transfer RNA Provides the energy needed for synthesis reactions Produced in the nucleus, this molecule specifies the exact sequence of amino acids of the protein to be made May be attached to the ER or scattered in the cytoplasm [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] SEXINV
A 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).
