Indicate which of the following items are associated with transcription or translation. This could be in prokaryotes or eukaryotes, or both. Group of answer choices: Translation OR Transcription Sigma binds to the promoter mRNA binds to the small ribosomal subunit Spliceosomes remove introns and splice together exons Nucleotides are added from the 5' to 3' end tRNA anticodon binds to the corresponding mRNA codon STOP codon results in termination
The following is a DNA sequence of gene Z. The underlined sequence represents the promoter for gene Z and the underlined and italicized sequence encodes the gene Z ribosome binding (RBS) site. Transcription begins at and includes the T/A base pair at position 60 (bold) a. What are the nucleotides of the mRNA from gene Z?b. What are the amino acids encoded by gene Z?

The code for a fully functional protein is actually coming from an mRNA transcript that has undergone post-transcriptional processing which is essentially way too different from the original code in the DNA template. Given: Val-His-Leu-Thr-Pro-Glu-Glu (Protein with known amino acid sequence) Requirement: Original DNA code. Itemize the steps you would take to get to know the original DNA code of the protein in focus.
Match the term with its definition comparing genomic DNA, mRNA, and proteins. You may only use each option ONCE. where transcription starts. where translation ends a chemical group that indicates the first nucleotide that was added to the mRNA a chemical group that indicates the first amino acid that was added to the polypeptide a DNA sequence that is neither transcribed nor translated a non-protein coding region upstream of the start codon in the mRNA promoter complimentary base-pairs with the codon amino-terminus a DNA sequence that is transcribed, but not intron translated [Choose ] stop codon +1 site tRNA 5-prime UTR start codon exon 5-prime triphosphate promoter amino-terminus 5-prime triphosphate stop codon
For each of the following items, fill in either the DNA strand, the MRNA codons, the tRNA anticodons, or the amino acid sequence that have been left blank. If several sequences might work, choose only one. Furthermore, circle the start and the stop codons of each mRNA sequence. 1.

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.
Complete the protein synthesis for the partial DNA sequence for a normal FGFR3 gene (TOP) and mutated FGFR3 gene (BOTTOM). Remember, when filling in mRNA, use capital letters only. When filling in amino acids, use three letters, with the first letter capitalized. If you do not use this format, your answer may be marked wrong.

Consider this list (below) of steps involved in translation. These steps are out of order. TRANSLATION: 1. the small and large ribosomal sub-units unite2. two amino acids join together.3. another tRNA anti-codon bonds with another mRNA codon 4. an initial tRNA bearing a specific amino acid arrives at the ribosome 5. the process continues until a protein molecule is completed6. at the synthesis site, initial mRNA codons are inserted
Explain why mature mRNA transcripts is a different size that pre-mRNA transcripts. Be sure to include the name of the protein-ribonucleotide complex that’s involved.
a) What is a mutation in molecular terms? b) a mutation deletes a base in the genomic DNA discuss how that will affect the reading frame and expression product production. Using the following list of codons describe, using diagrams etc., how information stored in the DNA is translated into a peptide. Be sure to discuss all steps. In other words, use a diagram and give me sequences, transcription and translation steps. Show the sequences of the sense and the other DNA strand, the mRNA and the tRNA’s.
