Comparing DNA and RNA
The difference in the number of strands of DNA to RNA...
What is:
RNA is one stranded and DNA is two stranded.
The three types of RNA are...
What is:
mRNA (messenger)
tRNA (transport)
rRNA (ribosomal)
The process of transcription is...
What is:
How mRNA is made from a DNA strand template.
On a strand of prokaryotic DNA, the _____________ binds to the operator. When this is bound to the operator is does not allow transcription to occur.
What is:
A repressor.
A point mutation affects...
What is:
Nitrogenous bases in DNA.
(alternate answer could be codons)
While DNA has the base Thymine, RNA contains...
What is:
Uracil
In a strand of DNA the sequence of nitrogenous bases are as follows
ATG CCG ACT
After transcription, the corresponding strand would be...
What is:
UAC GGC UGA
After transcription, mRNA is shortened by keeping pieces called __________ and discarding pieces called ___________.
What is:
Exons and introns.
On a strand of DNA, this location indicates where RNA polymerase must bind in order to begin transcription.
What is:
The promoter.
A chromosomal mutation affects...
What is:
Whole sections of chromosomes (big sections of DNA)
RNA nucleotides are composed of a phosphate, a Nitrogenous base and a 5 carbon sugar. The five carbon sugar is...
What is:
Ribose
Ribosomes are composed of...
What is rRNA and Protein
During translation, mRNA and tRNA join at a Ribosome to make____________ which are made from______________ carried by the tRNA.
What is:
polypeptides/proteins and amino acids.
The TATA box on eukaryotic DNA indicates...
What is:
When a gene is about to begin.
A point mutation called deletion occurs when...
What is:
A nitrogenous base is taken out of a DNA or RNA sequence.
The process where a new strand of DNA is made is known as...
What is:
Replication
The purpose of tRNA is to...
What is...
Match codons on mRNA to the anticodons and transport amino acids to the ribosomes.
In mRNA, sections of three nitrogenous bases are known as...
What is:
codons
Transcription factors (which attract or block RNA polymerase) bind to this location on eukaryotic DNA.
What is:
an enhancer
Duplication, a type of chromosomal mutation occurs when...
What is:
When a section of chromosome is repeated.
RNA and DNA are both located in a cell. RNA can be found in this/these part(s) of a cell...
What is:
The nucleus and the cytoplasm.
The enzyme used to make a strand of RNA from a DNA template is known as...
What is:
RNA Polymerase
The codon CCC aligns with the amino acid...

Proline
Hox genes are sections of chromosomes that determine cells specialized for...
What is:
Body segments of organisms.
Mutations can have positive and negative effects. Polyploidy, a type of mutation occurs when...
What is:
An organism has several set of chromosomes
(this can be good or bad. Good for plants, bad for humans)
