Stop codon - Study guides, Class notes & Summaries

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...

aminoacyl-tRNA synthetase - ️️During protein synthesis, an enzyme that attaches the correct amino acid to a tRNA molecule to form a "charged" aminoacyl-tRNA. Ribosome Anatomy - ️️APE where are the amino acids bonded together in the ribosome - ️️P slot GTP - ️️A nucleotide composed of guanine, ribose, and three linked phosphate groups. It is incorporated into the growing RNA chain during synthesis of RNA and used as a source of energy during synthesis of proteins elon...

Coupled transcription and translation - correct answers Ribosomes bind mRNA while mRNA is still being created, so that translation begins while transcription is still occurring - Advantage of lacking a nucleus Translation initiation - correct answers - Initiation factors bind ribosome to the ribosome binding site known as the Shine Delgarno sequence (AGGAGG) - Begins at start codon 1. 30s subunit binds mRNA 2. IF2 interacts with initiator tRNA 3. fMet-tRNA binds to start codon 4. Assoc...

Information in DNA - ️️same as mRNA, transcription termination and initiation information, splicing information catalytic domain - ️️protein domain in enzyme-linked receptors, activated by a conformational change induced by the ligand-binding domain, inhibits host cell protein synthesis and interacts with substrate to cause enzyme reaction tRNA - ️️An RNA molecule that functions as an interpreter between nucleic acid and protein language by picking up specific amino acids and r...

Transcription - Answer synthesis of RNA from DNA Transcription results in - Answer mRNA RNA polymerase makes - Answer mRNA mRNA - Answer makes proteins RNA polymerase - Answer binds to DNA Transcription factors (TFs) - Answer A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription - Answer RNA polymerase reaches a terminator sequence (Stop codon) and ...

CMMB 413 Exam with 100% Correct Answers | Verified | Latest 2024 Version Types of DNA Variation - single nucleotide variant (SNV) - small nucleotide insertion/deletion - dynamic mutations - microsatellite - copy number variation (CNV) Single Nucleotide Variants (SNVs) - most common type of sequence variation - >3 000 000 per person - can be benign or disease causing Initiation Codon (Start Codon) AUG (methionine) Stop Codons UGA, UAA, UAG 20 number of amino acids 64 number of dif...

Protein Synthesis Race Questions and Answers Already Passed What is the role of RNA polymerase in protein synthesis? RNA polymerase is responsible for transcribing DNA into mRNA during the process of transcription. How is protein synthesis affected if the ribosome malfunctions? If the ribosome malfunctions, protein synthesis can be halted or produce defective proteins, potentially disrupting cellular functions. What happens during the initiation phase of translation? During init...

Which strand is produced more rapidly? - ANSWER-Leading strand During DNA replication in the lagging strand there is production of this component? - ANSWER-Okazaki fragment How many "stop" codons exist? - ANSWER-3 The double helix of DNA is wrapped about 1¾ times around which of these components? - ANSWER-Nucleosome Which enzyme unwraps the double helix? - ANSWER-Helicase In the ribosome, what is the name of the bond that links one amino acid to the next? - ANSWER-peptide bonds...

Transcription synthesis of RNA from DNA Transcription results in mRNA RNA polymerase makes mRNA mRNA makes proteins RNA polymerase binds to DNA Transcription factors (TFs) A regulatory protein that binds to DNA and affects transcription of specific genes. Can wither activate or repress expression of genes Termination of transcription RNA polymerase reaches a terminator sequence (Stop codon) and detaches from the templateTranslation Process by which mRNA is decoded and a protein is produc...
