Termination transcription - Samenvattingen, Aantekeningen en Examens

RNA polymerase - ANSWER pries the two strands of DNA apart and joins the RNA nucleotides as they base-pair along the DNA templates promoter - ANSWER DNA sequence where RNA polymerase attaches and initiates transcription Synthesis of RNA transcript - ANSWER initiation; elongation; termination synthesis of RNA transcript initiation - ANSWER after RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point of the template stra...

karyotyping - number and type of chromosome present Barr body - -condensed inactive X chromosome near nucleus of cell -all females have 1 Barr body nondisjunction - failure of chromosomes to separate during meiosis autosomal nondisjunction - -failure of chromosomes (other than sex chromosomes) to separate during meiosis -exs: trisomy 21, trisomy 18 translocation - portion of one chromosome is transferred to another (usually nonhomologous) abnormal egg (XX) x normal sperm (X) - -...

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...
