Two cells use the same segment of DNA to produce two different proteins. The MRNA transcribed by cell A contains more introns than does the MRNA produced by cell B. Which of the following is true about the proteins of these cells? O A The protein for cell A is longer. O B. The protein for cell A is shorter. O C. Cell A produces more of this protein. O D. Cell A produces less of this protein.

You are studying pancreatic cancer have matched samples of tumor and healthy pancreatic tissue. You use a microarray to determine gene expression differences between these two sample. You label the healthy tissue cDNA with red fluorescnce and the tumor cDNA with green. You apply these cDNAs to your chip. Beta-actin is a housekeeping gene required for cell structure. What color would you expect the spot for this gene to be?    a. Red   b. Green   c. Yellow   d. No color   e. None of the above

You have 2 genes side by side on a chromosome, gene A and gene B. In your cell your RNASE enzyme that degrade MRNAS starting at their poly A tail is no longer functional. Choose the description that best describes the end result of this mutation. O a No MRNA can be degraded and resulting proteins will forever be made in the cell O b. There is no etfect on the cell O c. Gene A MRNA cannot be degraded and resulting Protein A will forever be made in the cell Od. Gene B MRNA cannot be degraded and resulting Protein B will forever be made in the cll

36. In the cell depicted in the picture, the ribosome is labeled b. c. d. 37. A gene mutation is none of these b. may orise spontaneously. a change in the nucleotide sequence of DNA. is is all of these. e. moy be caused by environmental agents. c. d. 1P BDACE

Section 2: Protein Synthesis Protein synthesis is the process whereby a gene of interest is transcribed into a strand of mRNA, which is subsequently translated into an amino acid sequence that will ultimately fold into a functional and highly specific protein.

In a fly egg, the nurse cells are killed before they can produce bicoid mRNA.  What will happen? Group of answer choices A. The larva will develop normally B. The resulting larva will have no head and two tail ends C. The resulting larva will have two heads D. The resulting fly will have legs growing out of its head

In the cancer gene detection lab, a restriction enzyme is added to the p53 genes taken from different locations in the person's body; this restriction enzyme cuts at the location of the mutation (if there is one present). When the enzyme is added to the p53 genes from the tumor, this will result in ____ fragments, and _____ bands on an electrophoresis gel when the DNA fragments separate out.

Chromatin is composed of: a. MRNA and ribosomes b. DNA and RNA c. rRNA and protein d. rRNA and tRNA е. DNA and protein

A gene whose expression helps to identify transformed cell is known as what?

What would happen if a chemical interfered with the ability of RNA polymerase to bind to the DNA molecule? Multiple proteins would be created O The RNA Polymerase would bind to a different place on the DNA O Transcription could not take place O The process of making proteins would start with translation
