100
Each side of the helix is composed of a long strand of these that are the building blocks of nucleic acids
What are nucleotides?
100
The base of DNA abbreviated A
What is adenine?
100
RNA stands for this
What is ribonucleic acid?
100
The first step of protein synthesis is the manufacture of a specific kind of RNA called this
What is messenger RNA (mRNA)?
100
A polypeptide is made up of these
What are amino acids?
200
DNA stands for this
What is deoxyribonucleic acid?
200
The base of DNA abbreviated T
What is thymine?
200
RNA is a molecule used to translate the code from the DNA molecule into this
What is protein?
200
This begins when a region of the DNA double helix unwinds and separates
What is transcription?
200
This is the step in protein synthesis where mRNA is decoded and a corresponding polypeptide is formed
What is translation?
300
These are pieces of DNA molecules that code for specific proteins
What are genes?
300
The base of DNA abbreviated G
What is guanine?
300
This is the only base that is in RNA but not in DNA
What is uracil (U)?
300
An enzyme called this picks up these unattached nucleotide bases and matches them to their complementary bases on the DNA template strand
What is RNA polymerase?
300
This is a molecule of RNA that contains a three-part nucleotide segment
What is transfer RNA (tRNA)?
400
The process of making genes into proteins is called this
What is protein synthesis?
400
The base of DNA abbreviated C
What is cytosine?
400
Messenger, ribosomal, and transfer RNA are all involved in this
What is protein synthesis?
400
When the mRNA strand has a sequence that is complementary to the original gene segment, the mRNA separates and leaves the nucleus, moving out into the cytoplasm to settle on an organelle composed of another kind of RNA called
What is ribosomal RNA (rRNA)?
400
This corresponds exactly to one of the twenty kinds of amino acids
What is anticodon?
500
This molecule carries the code for all the genes of an organism
What is DNA?
500
The A-T and G-C parings of base in DNA are called this
What are complementary pairs?
500
Proteins are composed of these which are chemical messengers that regulate some body functions
What are hormones?
500
On the surface of this, the process of translation begins
What is ribosome?
500
The start and stop these are a three-nucleotide segment that tells the ribosome that the translation process is beginning or ending
What are codons?
