Codon - Study guides, Class notes & Summaries

How does translation terminate? - ️️-stop codon (UAA, UAG,UGA) -instead of tRNA, release factor binds to ribosome, causing hydrolysis of the peptidyl tRNA, releasing the completed protein -ribosome dissociates into its subunits, releasing mRNA, release factor, and tRNA mRNA and protein synthesis are very energetically - ️️adding each subunit requires the conversion of an NTP to an NMP, equivalent to hydrolyzing 2 ATPS to ADP -elongation step consume multiple ATP/GTP -splicing and ...

ADP + P Glucose NAD Which of the following IS a capability of natural selection? Allows for the fittest individuals to produce more offspring. What does it mean when we say the genetic code is redundant? More than one codon can specify the addition of the same amino acid. What amino acid sequence will be generated, based on...

Translation - Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? - 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a specific codon into a specific amino acid What is the structure of tRNA? - - single RNA strand (70-90 nucleotide length) - four doub...

Dominance deviation: Correct Answer-d = heterozygous - midpoint Additive effect: Correct Answer-a = midpont - homozygous recessive a = homozygous dominant - midpoint Midpoint: Correct Answer-(Homozygous dominant + Homozygous recessive) / 2 Mutations: Correct Answer--Single point: SNP (single nucleotide polymorphism) •ex: A -->T or G-->C -Indels: gain or loss of nucleotides -Nonsynonymous: changes the amino acid sequence •Missense - amino acid(s) changed •Nonsense...

In his transformation experiments, what did Griffith observe? b. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. Cytosine makes up 42% of the nucleotides in a sample of DNA from an organism. Approximately what percentage of the nucleotides in this sample will be thymine? a. 8% At a specific area of a chromosome, the sequence of nucleotides below is resent where the chain opens t...

One of the most important advances in surgery arrived near the end of the nineteenth century. The British surgeon Joseph Lister hypothesized that using techniques to sterilize surgical tools and clean the skin at the site of the incision would reduce surgical site infections. Years later, Dr. Lister wrote this: "Nothing was formerly more striking in surgical experience than the difference in the behavior of injuries according to whether the skin was implicated or not. Thus, if the bones of the...

In the nitrogen cycle, which of the following steps involves removal of nitrogen from the atmosphere by bacteria? - ANSWERSNitrogen Fixation If enough H+ ions are added to pure water to raise the H+ concentration of the solution to ten times higher than the original concentration, what is the resulting OH- concentration of the solution? - ANSWERS10-8 M Fungi are able to reproduce asexually by creating conidiospores and sporangiospores. Which of the following is an accurate explanation for ...
