DNA vs RNA
What nucleotides are different in DNA than RNA?
DNA had thymine while RNA has uracil.
What are the base pairings?
A and T, G and C
How many types of RNA are there?
Three
How many nitrogenous bases are there?
Five
What is a karyotype?
It is a map on an individual's chromosomes.
Where is DNA found vs where is RNA found?
DNA is found in the nucleus of the cell while RNA is found in the cytoplasm
What is the Law of Complementary Base Pairings?
One strand determines the base sequence of another.
What are the three different types of RNA?
tRNA, mRNA, rRNA
How many rings does a purine have?
Two
In a karyotype, how are the pairs arranged?
Size, banding pattern, and centromere position
How are the shapes of DNA and RNA different?
DNA is double stranded while RNA is single stranded.
True or False: The amount of guanine is always equal to the amount of cytosine
True
What is the function of tRNA?
Transferring amino acids to make proteins.
How many rings does a pyrimidine have?
One
What does a karyotype show?
A karyotype shows the homologous pairs of chromosomes of an individual cell.
How are the functions of DNA and RNA different?
DNA stores and transfers genetic information while RNA helps make proteins.
What is adenine paired with?
Adenine is paired with thymine.
What is the function of mRNA?
Carries the message of DNA out of the nucleus
What are nitrogenous bases held by?
Hydrogen bonds
At the end
What is the difference between the sugars of DNA and RNA?
DNA has deoxyribose sugar while RNA has ribose sugar.
What is Guanine paired with?
Guanine is paired with Cytosine.
What is the function of rRNA?
It is the structural component of the ribosome
True or False: Thymine is found in RNA
False
What is a karyotype used for?
They are used to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells.
