Which regulatory proteins binds to specific DNA sequences with high affinity and plays a pre-dominant role in determining whether a genome segment is transcribed

Which of the following is a method through which cells can control their gene expression?     Increase a gene's stability using post-translational modifications     Epigenetic modifications of the DNA or histones to regulate DNA avilability     phosphorylation of thymidines     formation of crosslinks between the DNA strands and the histones

MRNA build to match the DNA message letter by letter

Correct regarding transcript processing: (A) Influences the amount and kinds of MRNA assembled from structural genes B Nuclear envelope selectively regulates passage of transcripts Phosphorylation of translated protein D Snipping out of transcript regions; chemical modification of transcript before it arrives at ribosome control

Explanation of the transcription and translation processes.

At which stage of the Central Dogma does MOST of the regulation of gene expression occur? O Post-transcriptional processing of the pre-MRNA O Post-translational processing of the polypeptide chain Transcription of pre-mRN O Translation of protein

Question: Define transcription and

How flexible protein domain helps to connect DNA binding domains to activation domains

How the genetic code relates mRNA codonsto protein structure

True or false: For each protein-coding gene, there is one promoter and one enchancer that act as regulatory elements for that gene.
