A DNA
B TRANSCRIPTION
C mRNA
D TRANSLATION
E PROTEIN
F TRANSCRIPTION is a process of making mRNA from a gene present in DNA with the help of transcription factors and RNA polymerase. This process is occur in nucleus of the cell.
G TRANSLATION is a process of making PROTEIN from the mRNA with the help of associated tRNA and rRNA (present in ribosome),This process is occur in the cytoplasm of cell.

How does gene flow differ from genetic drift? A. Gene flow is the random change in the frequency of alleles. B. Gene flow is the random change in a gene or chromosome. C. Gene flow is the guiding force of evolution. D. Gene flow is the spread of new genetic material from one gene pool to another.
Q1)Which of the following is not involved in control of gene expression in eukaryotes? A. Change to DNA sequence. B. Alternative splicing. C. Export of mRNA from the nucleus. D. Transcriptional repression. E. Destruction of mRNA Q2) Trans-acting regulators of gene expression include? A. promoters. B. histone deacetylases C. introns D. silencers E. the TATA box. Q3) Gene regulation in eukaryotes often involves which of the following, which are not also used by prokaryotes? A.RNA polymerase B.Transcription factors C.Histone modification...
Which of the following is NOT true of the Rb protein? a. It inhibits gene expression by binding to a gene regulatory protein. b. In the absence of mitogen it promotes cell proliferation. c. Its activity is controlled by phosphorylation. d. It is a tumor suppressor protein. e. None of the above (= all of the above are true).
Two genes (B and C) are transcription factors that affect the expression of gene A. The protein product of gene B allows gene A to be transcribed while the protein product of gene C doubles the rate of transcription of gene A. How does the expression of gene A differ between two individuals with the following genotypes? Assume lower case alleles produce non-functional proteins and each gene shows complete dominance. Individual 1: AA : BB : Cc Individual 2: AA...
In the context of E. coli fepCDG operon gene expression, Fe is A. an inducer. B. a corepressor. C. an effector. D. Two of the above.
For a hypothetical gene, how do the terms dominance and recessive relate to gene expression and how genes work? Question 22 options: a) A dominant phenotype results in the expression of the most beneficial genes resulting in increased chances of survival of the organism b) The allele with the dominant phenotype inhibits transcription of the allele for the recessive phenotype c) Both alleles get expressed, but the product of the allele with the dominant phenotype masks the phenotype of the...

Your grade will depend on how well you show cosmology the behavior of space through time is given by a function called the scale factor r(t). The variable,t, i behaviors of the scale factor depending upon estimates of the amount of matter in the universe. The amount of rogrom will start by asking the user for the epsilon value only...
In its active form it turns of gene expression. a.) Transcriptional repressor b.) Transcriptional activator c.) miRNA d.) tRNA e.) terminator
Describe a hypothetical scenario of gene flow for a trait. Be sure to describe each of the following key elements: a) frequency of the trait in the two populations prior to gene flow b) why gene flow occurs c) the consequences of the gene flow event in future generations
