What is a DNA Molecule made of repeating units?
100
It is the two strands of DNA twisted around a central axis to form a double spiral similar to a spiral staircase.
What is a Double Helix?
100
Replication.
What is the process of copying a DNA molecule ?
100
RNA
What consist of a single strand of nucleotides?
100
RNA polymerase.
What enzyme binds to a DNA molecule and causes the separation of the strands of DNA?
200
Sugar, Phosphate, and Nitrogenous Base
What are the three distinct part of a nucleotide?
200
James Watson and Frances Crick.
Who were the first people to describe this in 1953?
200
Helicase.
What is the enzyme that helps Replication occur in the Nucleus?
200
Ribose is RNA/ DNA is deoxyribose.
What is RNA's sugar?Also what is DNA's sugar?
200
Promoter.
What marks the beginning of the DNA chain that will be transcribed?
300
Purines and Pyrimidines
What are the 2 classes of Adenine, Thymine, Guanine, and Cytosine?
300
They are formed by alternating sugars and phosphates.
What does the side of the ladder (DNA) formed by?
300
DNA Polymerase.
What is the enzyme that catalyzes the formation of sugar to a phosphate bond?
300
Uracil
What base does RNA have?
300
It moves to the cytoplasm.
What happens to the mRNA at this point in time?
400
Pyrimidines
What is the class of base that consist of a single ring that include C and T?
400
Hydrogen Bonds.
What are the two strands held together by?
400
G C T A G
What is the replication of DNA if this is what you had? C- G- A- T- C-
400
transmits information from the DNA to the ribosome for protein synthesis.
What does mRNA do?
400
Template.
What is the one separated chain that will be used for transcription?
500
Purines
What is the class that is composed of two rings of molecules and include A and G?
500
Complementary Base Pairs
What is the pairing of bases along one strand and is the exact copy of the adjacent strand?
500
Two DNA strands.
What breaks the bonds when helicase comes in?
500
transfers amino acids and puts them in the correct order.
What does tRNA do?
500
Nucleus.
Where do these events occur?
