DNA REPLICATION, TRANSCRIPTION AND TRANSLATION

What do you call a segment of the DNA that codes for a specific trait?

• chromatin

• genome

• RNA

• 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

Answer explanation

it is located in the NUCLEUS of most cells

What is the basic unit of DNA?

• nucleotide

• protein

• RNA

• nucleus

Answer explanation

Which ones show the complementary base pairing of DNA? Check all that applies

• Adenine with Thymine

• Thymine with Cytosine

• Adenine with Uracil

• Cytosine with Guanine

Answer explanation

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

Answer explanation

This photo by Franklin and Wilkins was an important evidence in identifying the structure of the DNA

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

Answer explanation

All the statements about DNA are correct but the one that describes the SEMI CONSERVATIVE MODEL is the one that states that
old or parental strands separate and act as templates to synthesize new DNA (2 DNA strands are used as template strands during replication)

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

Answer explanation

It is the process of copying DNA, not RNA
