BSC 101 Exam 2 Questions and Answers 100% Pass Graded A+
DNA is all over our body and can be retrieved through anything with cells - Answers True
Complete the hydrogen bond: Adenine - Answers Thymine
Complete the hydrogen bond: Ctyosine - Answers Guanine
How many bonds does AT form? - Answers 2
How many bonds does CG form? - Answers 3
each hydrogen bond is weak until formed together on helix - Answers True
Copying of DNA code to RNA. Happens one nucleotide at a time so it is complementary to DNA -
Answers Transcription
When does the DNA code get trasnalted into a protein? - Answers After it is copied to a molecule of RNA
When RNA gets translated into a protein - Answers Translation
What does the universal genetic code mean? - Answers All ogranisms are related and use teh same
genetic code
Is it possible to take a gene from one organism to another in a different individual or species? - Answers
Yes
A 3 letter word that acts in the coding of amino acids - Answers Codons
Is there more than one codon for each amino acid? How many in total? - Answers Yes, there is more
than one. There are 64 total for 20 total amino acids.
Does every cell with a specific gene get transcribed into RNA the translated into a protein? - Answers No
Process of turning on a gene in order to produce RNA and protein - Answers Gene expression
What must happen for a cell to function properly? - Answers The correct proteins must be synthesized
at the correct time
Do all cells have the same complete genome? - Answers Yes
Does every cell express all the genes? - Answers No, only the ones that make it function how it is meant
to
Modification of genetic material from living organisms so they can produce new compounds and
perform new functions. - Answers Biotechnology
, What is biotechnology used for in agriculture? - Answers Selective breeding
How is DNA extraction perfromed? - Answers By extracting nucleic acid by breaking open the cell by
using enzymic reactions to get rid of all the undesired macromolecules which then physically separates
the DNA.
Which biotech tool forms a gelatinous mass? - Answers DNA extraction
When DNA strands are separated based on length and molecules by their charge - Answers Gel
electrophoresis
Is DNA negatively or positively charged? - Answers Negatively
Which biotech tool takes a few copies of DNA and makes millions of copies - Answers Polymerase chain
reaction
Where can copies be made for a polymerase chain reaction? - Answers In the specific region of the
genome
What biotech tool is the creation of genetically identical copy (basic cloning) - Answers Molecular
cloning
What is commonly used in molecular cloning? - Answers Bacteria
What is a plasmid and how is it used for molecular cloning? - Answers Small circular DNA molecule that
replicated independently of the chromosomal DNA in the bacteria. The DNA fragment tis placed here to
get it into the bacteria cell.
When are plasmids reintroduced? - Answers When they are put into the bacteria host for replication
What biotech tool makes a copy of an entire multicellular organism? - Answers Reproductive cloning
How does reproductive cloning happen? - Answers Remove the haploid nucleus of one egg cell, take the
diploid nucleus from one body cell. Then human DNA is introduced and stimulated to divide.
What biotech tool involves the introduction of nonmutated gene at a random location in a genome in
order to cure a disease by replacing a possible absent protein. - Answers Gene therapy
What do traditional vaccines do? - Answers Use weakened or inactive forms of a virus to stimulate a
primary response in the adaptive immune system.
Animals that have been modified to express recombinant DNA - Answers Transgenic animals
What do genomics study? - Answers Set of genes, nucleotide sequence and organization, and
interactions between other species.
How are advances in genomics been made possible? - Answers By the DNA sequencing technology
