RNA
100
prophase, metaphase, anaphase, telaphase
What are the four phases of mitosis
100
What is semiconservative DNA replication
One parental double helix is replicated into two daughter helixes where one strand of the parent is in both
100
Synthesis of RNA in the nucleus
What is transcription?????????
100
type of RNA that carries the code for a protein coding gene from DNA to ribosomes
What is mRNA (messenger RNA)?
200
anaphase
In what stage of mitosis do the sister chromatids seperate
200
adenine guanine cytosine and thymine
Name the nitrogenous bases
200
the function of the DNA helicase
What is unzipping the parental helix by breaking H-bonds
200
What are the steps in transcription and translation?
Initiation Elongation Termination
200
What is ribose
a sugar
300
growth 1
In what stage of interphase does cell check for DNA damage
300
a phosphate group, a sugar deoxyribose, one of the four bases
What are the three parts of the Dna nucleotide
300
the machines of DNA replication
What are enzymes?
300
The nitrogenous base that takes place of thymine in RNA
What is uracil?
300
What are 3 ways that RNA differs from DNA?
RNA contains ribose instead of deoxyribose, uracil instead of thymine, and RNA is single stranded
400
spindle fibers
What are the fibers that extend from centriole to to centromere
400
A space in between helices that is broken by a helicase which allows RNA to transcript the DNA.
What is a replication bubble?
400
What happens during termination in transcription?
RNA is released, RNA polymerase is released, DNA remains constant
400
What is the nucleotide sequence of RNA transcribed from DNA with a nucleotide sequence of GCTAATCCG
What is CGAUUAGGC
500
telaphase
What is the reverse of prophase
500
the 5' (5 prime) side ends on what part of the DNA's sugar phosphate backbone?
What is phosphate?
500
Why does one strand of the parental helix loop around itself when in the process of replication?
The strand needs to be looped in order to be pulled through the polymerase the correct way.
500
How is gene expression regulated during transcription?
By transcription factors, and ribozymes cut mRNA to exactly the right code.
500
Where do amino acids link to peptide bonds?
What are catalytic sites?
