Chapter 7, Problem 2PIT
Summary Introduction
To determine:
Where do promoters, terminators, stop codons, transcription factors, RNA polymerase and enhancers fit into this concept map.
Concept introduction:
The process of central dogma in biology helps to explain the flow of genetic information. DNA carries genetic information and its transfer to 
by the process of transcription and it is converted into protein by the process of translation. It involves a process of replication, transcription, and translation.

If a gene sequence is more tightly coiled around histones, then which of the following is the most likely consequence?
A) This gene is more likely to undergo mutation as it is being expressed
B) This gene is unlikely to be transcribed while in this conformation
C) This gene will be transcribed often while in this conformation
D) This gene will be translated more efficiently
.
Which of the following is true of phase variation?
A) OIt is triggered by stalled ribosomes.
1S
B) OIt is part of transformation.
o ORecombination leads to an inverted DNA sequence.
D) OIt targets mRNAs for degradation or can block ribosome binding to mRNA molecules
E) Olt prevents CRP interaction with RNA polymerase, thereby blocking its access to the promoter
Which statement is false:
A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide
B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down
C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon
D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome
E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien
