BIO 340 - Mastering Genetics Exam WithComplete Solutions 2025-2026
What do the genome, the proteome, and the transcriptome of an organism share?
All are global descriptions of a different aspect of how molecular information is stored
Genome
-all the information in DNA
Transcriptome
-all the RNA that is synthesized by RNA pol from DNA
Proteome
-all the protein that is synthesized by ribosomes translating mRNA
Modern genetics is divided into three main branches. Of the following, which branch is
sometimes called "transmission genetics" and is specifically concerned with the
passing of traits from one generation to the next?
Mendelian
Watson and Crick relied on evidence from a number of different sources to piece
together the structure of DNA. From Rosalind Franklin's X-ray diffraction data, what can
be said that they learned?
DNA is a duplex, meaning it takes the form of two strands twisted together in a helix.
We have an expert-written solution to this problem!
, In double-stranded DNA, the percentages of adenine and thymine are approximately
equal to each other, as are the percentages of cytosine and guanine. This relationship is
better known as what (named for the person who made this discovery)?
Chargaff's rule
What type of bond is formed between the 5 phosphate group of one nucleotide and the 3
hydroxyl (OH) group of the next nucleotide?
phosphodiester bond
What type of bond is formed between complementary base pairs to unite the two DNA
strands into a double helix?
Hydrogen bond
The polarities of the complementary nucleic acid strands go in opposite
directions-5-to-3 and 3-to-5. The 5 designation refers to the attachment of what
chemical group on the 5 carbon of the deoxyribose sugar?
phosphate group
Watson and Crick didn't accomplish their DNA structure model by conducting any sort
of experiment in a laboratory. They worked off from other researchers' contributions:
Erwin Chargaff, Rosalind Franklin, and Maurice Wilkins. Which of the following is
evidence that DNA nucleotides are packaged as complementary base pairs?
Percentages of adenine and thymine are roughly equal to each other, and the
percentages of cytosine and guanine are roughly equal to each other.
Which kind(s) of RNA is/are translated into proteins?
mRNA
What is the process of synthesizing proteins from mRNA sequences?
translation
