gene
The complete set of genetic make-up is called a ___________.
DNA
genome
protein
nucleotide
All these describe DNA EXCEPT for:
it has an anti-parallel structure
it is a double-helix
it carries genetic information
it is found in the ribosomes
What is the basic unit of DNA?
nucleotide
protein
RNA
nucleus
Which ones show the complementary base pairing of DNA? Check all that applies

Which pair of scientists produced the image of DNA via x-ray?
James Watson and Francis Crick
Matthew Meselson and Franklin Stahl
Rosalind Franklin and Maurice Wilkins
Thomas Schwann and Robert Hooke
Which pair of scientists is credited for discovering the DNA's double helix, anti parallel structure?
Rosalind Franklin and Maurice Wilkins
James Watson and Francis Crick
Thomas Schwann and Robert Hooke
Matthew Meselson and Franklin Stahl
Which statement explains the SEMI-CONSERVATIVE model of DNA that Meselson and Stahl found when they were working with E. Coli bacteria?
old or parental strands separate and act as templates to synthesize new DNA
DNA is double stranded, and the strands are antiparallel because they run in opposite directions
DNA has a sugar-phosphate backbone
DNA contains genetic information
DNA Replication is the process of copying DNA.
Which is NOT PART of DNA REPLICATION?
Initiation
Elongation
Transcription
Termination
Check all the statements that are correct about DNA Replication.
It is the process of copying RNA.
process of producing two IDENTICAL replicas of DNA (daughter cells) from one original DNA molecule
It happens during the S stage of Interphase.
the steps involve Initiation, Elongation and Termination
This is the step of DNA REPLICATION where unwinding of complimentary DNA happens with the help of the Helicase enzyme that breaks the hydrogen bonds between base pairs that are complementary,
Elongation
Initiation
Translation
Termination
This is the process of DNA Replication where each strand of unwound DNA gets a new complementary strand with the help of primase and DNA polymerase enzyme
Initiation
Termination
Elongation
Transcription
Which enzyme is responsible for adding nucleotide to template strands forming a new complementary strand? It makes sure to add a complementary strand in the 5’ to 3’ direction
helicase
ligase
primase
DNA polymerase

3' to 3'
5' to 3'
5' to 5'

Which is the complementary strand of the given strand?
None of the above
Which is the complementary strand of the given strand?
Which ones are stages in PROTEIN SYNTHESIS -the process where cells construct proteins? Check all that applies
Translation
Transformation
Transcription
Termination
In the TRANSCRIPTION stage of Protein Synthesis,
DNA template is used to make a strand of mRNA (single strand) where the
RNA Polymerase unwinds and unzips the DNA.
WHERE DOES TRANSCRIPTION OCCUR?
cytoplasm
