What"s the difference in between synonymous and nonsynonymous mutations? Nonsynonymous mutations execute not an outcome in a readjust in the amino acid sequence that the coded protein. Identified mutations execute not an outcome in a adjust in the amino acid sequence of the coded protein. synonymous mutations take place much less frequently than nonsynonymous mutations.

Which the the complying with proteins is possibly the biggest in the person genome and mutations of it have been implicated in autism, dyslexia, schizophrenia, pundit disability, Tourette syndrome and language impairment? CNTNAP2 FOXP2 TATAAA binding protein (TBP) SRGAP2

Under what circumstances can the replication fork be bidirectional? once the origin of replication moves in one direction, and the replication eye in the opposite. as soon as the beginning of replication creates 2 replication forks that relocate in opposite directions. as soon as the beginning of replication creates two replication forks that relocate in the same direction at different speeds once a separate beginning is supplied for every strand

Why go it take it so lengthy for the beginning oriC to it is in able initiate a 2nd round that replication? because Dam methylase needs to interact with DnaA to be set off because SeqA binds to hemimethylated DNA and sequesters it to the membrane due to the fact that SeqA needs to it is in methylated by Dam methylase due to the fact that the initiator protein DnaA cannot be discovered

Which enzyme methylates bacterial oriC? EcoKI methylase Dcm methylase Mec methylase Dam methylase

What is the replication fork? point in the genome which is composed of the ter sites allude in i m sorry RNA genome forms a hairpin point in the genome whereby to replication eyes meet suggest at i beg your pardon replication is occurring

Which explain is TRUE concerning replication control? chloroplast DNA display screens single-copy control. Mitochondrial DNA screens single-copy control. The bacter chromosome have the right to replicate number of times prior to cell division. The eukaryotic bio chromosome need to activate replication only once per cabinet cycle.

What is the role of Tus protein? It permits the replication forks to be quit by the ter website in both orientations. Although the replication fork moves 10x faster than RNA polymerase, the Tus protein acts to do it move even faster. The acts as a contrahelicase by unwinding DNA in opposing direction from the replication helicase, DnaB. It stops transcription when the replication machine is approaching.
It acts together a contrahelicase by unwinding DNA in the contrary direction from the replication helicase, DnaB.
Bacterial beginning of replication oriC is composed of ________________________? Eleven GATC/CTAG repeats methylated on guanines in both strands Eleven GATC/CTAG repeats methylated on adenines in both strands Eleven GATC/CTAG repeats methylated top top thymines in both strands Eleven GATC/CTAG repeats methylated on adenin in height strands only
