Module 1 Exam Questions
with 100% Correct Answers
DNA -> RNA -> Protein
a portion of the DNA, a gene, is transcribed to produce a complementary
strand of RNA; then the RNA is translated into protein .
✅✅
-The understanding that DNA is used to make RNA and RNA is used to
make protein - -Central dogma of molecular biology
A long molecule consisting of many similar or identical monomers linked
together.
ex nucleic acids (dna rna) - ✅✅-Polymer
-Nucleic acids are polymers of nucleotides.
A nucleotide consists of a nitrogenous base, a pentose sugar, and one or
more phosphate groups.
-DNA contains adenine, guanine, cytosine, and thymine
deoxyribonucleotides, whereas RNA contains adenine, guanine, cytosine,
and uracil ribonucleotides.
-DNA is double-stranded and forms a double helix structure that allows for
information storage.
Prior to dividing , a cell copies all of its DNA using -DNA replication to
ensure all new cells have the DNA they need.
-DNA Replication involves the formation of a replication fork, addition of
RNA primers to create a "handle" for DNA polymerase, synthesis of the
new DNA strand by DNA polymerase, and sealing the DNA backbone by
DNA ligase.
-RNA is single-stranded and is grouped into three types of RNA:
messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA
✅✅
(tRNA). All three types of RNA play an important role in the central dogm -
-Nucleotides
KEY CONCEPTS
deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) - ✅✅-two types
of nucleic acids
nucleic acids and polymers, which means they are made up of many
smaller units (monomers) connected together, much like a string of pearls.
, The monomers of nucleic acids are known as nucleotides. Each nucleotide
✅✅
includes a nitrogen-containing base, a five-carbon sugar or pentose (pente
means "five" in Greek), and one or more phosphates. - -DNA and
RNA are
nucleotides =
cytosine, guanine, thymine, adenine (DNA)
✅✅-The monomers of nucleic
(RNA)
cytosine, guanine, adenine, uracil -
acids(DNA and RNA) are known as
-nucleic acid
-polymer
✅✅-DNA
-made up of phosphate, deoxyribose sugar and purine base
-purine base of DNA= adenine,guanine, cytosine, thymine -
-nucleic acid
-polymer
-made up of phosphate, ribose sugar and purine base
-purine base of RNA= adenine,guanine, cytosine, uracil
single stranded - ✅✅-RNA
a two strand which isantiparallel, which means they have opposite 5' and 3'
✅✅
orientations, similar to a two-way street in which traffic is oriented in
opposite directions. - -The DNA the double helix is made up of
is semi conservated - ✅✅-DNA replication
-First, the DNA must be separated. This creates a replication "fork" where
the two original strands separate.
-Next, the new DNA is synthesized by a protein known as DNA polymerase
(its name comes from its function - it makes a polymer of DNA nucleotides).
-DNA polymerase takes individual nucleotides and matches them up to the
parental sequence to ensure they are a correct pair. If the pairing is correct,
DNA polymerase bonds the nucleotide to the growing strand of DNA.
-uses RNA primers. The addition of a primer to the single-stranded DNA
creates a double-stranded nucleic acid "handle" to which DNA polymerase
can attach and start making DNA
