Biology Flashcards
Are organic compounds that serve as
genetic information storage molecules.
Nucleic acid
What is the monomer of
NUCLEIC ACID?
Nucleic tides
Provides the information to make
proteins
Nucleic acid
is a naturally occurring
chemical compound that serve as the
primary information carrying molecule in
cell and make up genetic material.
Nucleic acid
A nitrogenous base with a six-membered ring, similar to benzene, that contains cytosine, thymine, and uracil as bases for DNA or RNA.
Pyrimidine
One of two chemical substances used by cells to construct the DNA and RNA building blocks.
Purine
Purine have?
Adenine
Guanine
Pyrimidine have?
Uracil
Thymine
Cytosine
3 TYPES OF RNA
mRNA – Messenger RNA
● rRNA – Ribosomal RNA
● tRNA – Transfer RNA
● Carries genetic codes from DNA to
Ribosomes
● Nucleus to Ribosomes
messenger RNA -mRNA
They transfer amino acids during
protein synthesis
Transfer RNA- tRNA
Consist of 80% of the total RNA in the
body found in the ribosomes.
Ribosomal RNA - rRNA
molecules that speed up
the rate of chemical
reaction.
Emzymes
are the ones the glues
together the nitrogenous
bases.
Hydrogen bonds
KEY PLAYERS in the process of DNA Replication
1.Helicase
- Primase
- DNA Polymerase
- Ligase
An enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis.
Primase
An enzyme which connects two strands for DNA together
Ligase
An enzyme that replicates DNA to build a new strand.
DNA polymerase
An enzyme that unzips / separates the double helix by breaking the hydrogen bonds between the complementary bases.
Helicase
The initializer
The builder
The unzipping enzyme
The gluer
Primase
DNA polymerase
Helicase
Ligase
A region of the DNA that was replicated will be converted into mRNA.
Transcription
Information in the nucleotide base
sequence of mRNA is used to dictate
the amino acid sequence of a protein.
Translation
is divided into groups of 3 which is
called CODON
mRNA
have a specific amino acid
attached to them which
corresponds to the mRNA
tRNA
● tRNA groups of 3 is called ?
Anticodon
are large category of mutations that
describe a change in single
nucleotide of DNA, that causes that
DNA to be different from the normal
type gene sequence.
Point mutation
It has no effect on the protein sequence
Silence mutation
