Document Summary
Dna opens, it is transcribed into mrna, mrna leaves the nucleus and attaches to ribosome, mrna is translated into its. Transcription factors amino acid sequence and a protein is made. Determine how and at what rate a cell will develop. Portions of dna that are not involved in synthesis of proteins are involved in control of structural genes. We cut out introns and put back together exons to synthesize proteins. We can also put the exons together in various ways so 1 gene can produce multiple proteins. Small sections of rna that bind to mrnas and affect translation into proteins. 60% of genes can be regulated by mirnas. When one of 2 alleles is inactive and the other allele is expressed often due to epigenetic mechanisms. Must have place to bind to dna and dna must have place to bind to transcription factor. Often work with co-regulators which regulate the transcription factors.
