The example and mechanism of positive and negative feedback control of the hypothalamus and pituitary. Introduction: Hormones are chemical messengers secreted by the glands into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors present on cells and they act through chemical signals. They regulate growth, development, blood pressure, metabolism , fluid concentration, and maintain homeostasis in the body.

Molecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA? Thank you

Molecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank you

Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank you
