Regulatory genes - Study guides, Class notes & Summaries

What does it mean to say that regulatory sequences are in cis? Correct Answer-they are one the same chromosome as the genes that they control Describe the distance between transcription regulator binding sites and the TATA box. Correct Answer-the transcriptional regulator binding sites are often really far away from the start of genes (10's of thousands of bp's long) If you see the TATA box on a strand of DNA, you know that this is the ________ of a gene. Correct Answer-promoter How w...

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...

Typical definition of GeneticsThe study of genes, heredity, and genetic variation What is a gene?•Basic unit of heredity •Sequence of DNA that codes for a product (RNA or protein) and it's regulatory regions •Located on chromosomes What is an allele?One of two or more versions of a gene What is a genome?•The complete set of genetic material in a cell (including mitochondrial, chloroplast, plasmid DNA) •Includes genes as well as non-coding DNA regions Genes vs Traits/phenotypes•G...

A species may coevolve with a number of species. It may interact with one species for generations. When the intensity of the conflict becomes impractical, it shifts to another species as a coevolutionary partner until their conflict forces it to switch partners again. What term is used to describe this pattern? A. coevolutionary arms race B. coevolutionary alternation C. reciprocal coevolution D. alternation of generations E. diversifying coevolution - ️️ANS B coevolutionary alter...

MCB4304 Exam Questions & Answers 2024/2025 Why does the estimated number of protein coding genes in prokaryotes correlate well with genome size? - ANSWERSBecause most genes are coding regions and prokaryotic DNA do not have introns Why does the estimated number of protein coding genes in eukaryotes correlate poorly with genome size? What is the estimated number of genes in humans? - ANSWERSBecause Euks have introns and some of our genes are regulatory sequences and non-coding DNA. many g...
