Single stranded and contains Uracil in place of Thymine.
What is RNA
100
each three-letter "word" in mRNA is known as
What is codons.
100
RNA-polymerase can bind to begin transcription
what is an operator.
100
The effects of mutations on genes vary wide , some have little effect or no effect and some produce beneficial variations some are negatively disrupt gene function
How do mutations effect genes?
200
Gene mutations that involve changes in one or a few nucleotides.
What are Point Mutations.
200
This type of RNA carries information from DNA to other parts of the cell.
What is messenger RNA
200
The decoding of an mRNA message into a protein is known as
What is translation.
200
A set of master control genes that regulate organs that develop in specific parts of the body.
What are Homeotic genes.
200
Dramatically change protein structure or gene activity
What do Harmful Effects do.
300
one base is changed to a different base.
What is substitutions.
300
This type of RNA assembles proteins on ribosomes composed of 2 subunits.
What is ribosomal RNA
300
Segments of DNA serve as templates to produce complementary RNA molecules
What is Transcription?
300
This code for for transcription factors that activate other genes that are important in cell development and differentiation.
What are Homeobox Genes.
300
mutations often produce proteins with new or altered functions that can be useful to organisms in different or changing enviroments
What do Beneficial Effects do.
400
a base is added to the DNA sequence and causes dramatic changes.
What is insertions.
400
This type of RNA transfers each amino acid to the ribosome.
What is transfer RNA
400
In introns portions that are cut out and discarded and exons spliced back together to form the final mRNA.
What is the difference between introns and exons?
400
These are located side by side in a single cluster and are arranged in the exact order in which they are expressed.
What are hoxgenes
400
This mutation causes your skin to lose pigmentation and for the eyes to be a red color.
What is Albinism.
500
a base is removed from the DNA sequence.
What is deletions.
500
Transcription requires an enzyme similar to DNA polymerse
What is RNA polymerse
500
Each tRNA molecule has three unpaired bases
What is Anticodon.
500
DNA binding proteins in prokaryotes regulate genes by controlling transcription.
How are prokaryotic genes regulated?
500
This mutation causes the eye to look like a kittys c:
