Questions and situational problems I. A particular gene codes for a mature mRNA containing 900 bases, which is translated into a 40 kDa protein. A mutant form of the gene created by a single point mutation yields an 830-base mature mRNA yielding a 37 kDa protein with modified enzymatic activity. The analysis shows that the mutation has resulted in a 22 amino acid deletion within the protein. What is the most likely effect of the mutation? Explain.

Question: Some scientists have concluded that this method of gene therapy will be a more effective long-term treatment for SCD than HSCT. Use all the information provided to evaluate this conclusion. I dont know how to answer this question pls help:(

Concept Overview: Protein Synthesis Task 2: Review the process of protein synthesis by placing the cards in their appropriate category. Think before you drop - This is an all or nothing type of question. Double check that you are happy with where you placed all of the options before you submit the knowledge check.

Practice question 1D) In the boxes on the image, label the N and C termini of the csRu protein. . Also on the schematic above, draw the csRH protein as you would find it at the plasma membrane. Be sure to label the N and C termini of the protein you draw to indicate its orientation. The csRu MRNA and protein are represented in the diagram below. mRNA 5' AUG 3' ribosome protein DNA ligand binding domain signal kinase transmembrane binding domain sequence domain domain cytoplasm plasma membrane extracellular fluid

PLEASE HELP! Please use the following terms and describe how each works to control protein expression. - Chromosomal level- Transcription- mRNA transcript- mRNA degradation- Translation blockage- Protein degradation

Instructions -Answer thr Questions properly. MUTATION: Fill in the correct nucleotide base pairing and amino acid sequence of the mutated DNA "MUTATED DNA" (SEE IMAGE) a. What is the 3’-5’ DNA sequence? (FORMAT: XXX-XXX-XXX-XXX-XXX) b. What is the mRNA sequence? (FORMAT: XXX-XXX-XXX-XXX-XXX) c. What is the tRNA sequence? (FORMAT: XXX-XXX-XXX-XXX-XXX) d. What is the amino acid sequence? (FORMAT: XXX-XXX-XXX-XXX-XXX) e. What is the most convincing type of mutation had occurred? - Substitution - Missense (Frameshift resulting Missense; Frameshift resulting Nonsense; Substitution – Silent; Substitution – Missense; Substitution – Nonsense)

PLease help, double and triple check your answers, im using this to study, these questions are NOT graded they are PRACTICE problems

Genetics problem part 1. Part 2 attached in new question Draw and Label what is happening in this scenario: The antibiotic erythromycin disrupts protein synthesis by binding to the 50 S subunit and preventing ribosomal translocation. No other step in protein synthesis is affected.   a. If you are performing an in vitro translation reaction and add erythromycin just before the 3rd bond that is about to be made and wait a few minutes to look at the ribosome, you will find which tRNA in site A? b. If you are performing an in vitro translation reaction and add erythromycin just before the 3rd bond that is about to be made and wait a few minutes, the ribosome should have the carboxyl end of amino acid #3 covalently bonded directly to

Need help  Please answer both.its all a one question

answer with a thorough explanation please!

Question: What is a loss of function of a certain protein that prevents nucleotide metabolism and prevents DNA synthesis - this gene is expressed in all tissues but is expressed at the highest levels in bone marrow?

Problem B. DNA: Codon SegmentingThe way that DNA is often interpreted as genes is in groups of three nucleotides at a time, called “codons.” Thus, the DNA strand dna_str = 'agctttcattctgac' Can be broken into codons in the following three ways: agc ttt cat tct gac a gct ttc att ctg ac ag ctt tca ttc tga c # reading frame 0 # reading frame 1 # reading frame 2 Notice that in these lines, we start reading codons at string indexes 0, 1 and 2. The three different start indices are known as reading frames, and are called reading frame 0, reading frame 1 and reading frame 2, respectively. It is not always clear which of these frames will be read by genetic transcription mechanisms, so it is often useful to be able to be flexible and consider any of them when working with DNA strands. Write a function segment that takes as an input a string containing a DNA strand, and a reading frame (0, 1 or 2) to use. The function should return a list containing the sequence of individual codons. You…

Modified True or False: Write TRUE if the statement is correct, if the statement is false, change the word/ words in (parenthesis) to make it correct 1. Between the two strands of a DNA segment, the nitrogen bases are held together by (phosphodiester bond). 2. When the ribosome encounters (UAG) in the mRNA it will terminate translation. 3. (mRNA) moves from the nucleus to the cytoplasm prior to translation
