Regulatory genes Study guides, Class notes & Summaries

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...

Question 1 1 out of 1 points A noncompliant patient states, “Why do you want me to put this poison in my body?” Identify the best response made by the psychiatric-mental health nurse practitioner (PMHNP). Answer: C. “Most medications that work in the brain will result in restoring an imbalance of one or more neurotransmitters that your body already produces helping to alleviate your symptoms .” Question 2 1 out of 1 points Ms. Hill is currently being treated for schizophrenia...

MCDB 3135 Final Exam Questions & Answers 2023/2024 What is the most common step where regulation occurs, and what advantage does a cell have in regulating this step? - ANSWER-transcription initiation is most common regulatory step in bacteria and eukaryotes • eliminates wasteful investment of cellular energy in mRNA and protein synthesis • regulation downstream of transcription initiation can respond more rapidly regulatory proteins - ANSWER-that bind "regulatory sites" in DNA ...

All cells that make up an organism contain the exact same DNA sequence (genome) however individual cell-types look and function very differently. Why? Correct Answer-each cell-type expresses a unique set of genes of the genomic DNA. Speaking of genotype and phenotype how are these terms defined? Correct Answer-the genotype defines the genetic information (gene) and the phenotype the outcome of gene expression. Which of the following describes a functional gene? Correct Answer-a gene is def...
