DNA Replication and Protein Synthesis

Front

What percent of a DNA strand is Cytosine if it is 20% Thymine?

Back

30% Cytosine

Front

What is the first step of DNA replication?

Back

An enzyme (Helicase) separates the double helix.

Front

How does tRNA read a codon?

Back

It contains an anticodon that bonds with the mRNA.

Front

Which nitrogenous base is present in RNA but not DNA?

Back

Uracil.

Front

What are the bonds that join the two nitrogenous bases in the middle of the DNA structure?

Back

Hydrogen bonds.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding complementary nucleotides.

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the function of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides that codes for an amino acid.
