What are the three types of RNA?
mRNA, tRNA, rRNA. Bonus: Do you want the bonus?

What is the central dogma of molecular biology?
DNA is transferred to RNA and then RNA is transferred into proteins.

A mutation that involves a one or a few nucleotides is a...
point mutation
200
The order of nitrogenous bases in DNA determines the order of what in proteins?
Amino Acids

What does RNA polymerase do?
Binds to DNA during transcription and separates the two DNA strands.
200
What are the three main parts of a RNA nucleotide?
mRNA, tRNA, and a ribosome organelle

What binds to DNA and assembles nucleotides into a strand that is complementary to the DNA template?
RNA polymerase
300
Which type of RNA brings information in the genetic code from the nucleus to other parts of the cell?
mRNA
300
Why are Hox genes that are found in different animals so similar to each other?
They all come from a common ancestor
300
From which which molecules are mRNA molecules transcribed?
DNA

the tRNA bases called the _______________ are complementary to three consecutive nucleotides on an mRNA molecule
Anticodon
400
What happens during translation? A. Messenger RNA is made from a DNA code. B. The cell uses mRNA code to make proteins. C. tRNA is made from a messenger RNA code. D. Copies of DNA molecules are made.
Choice B
400
What must happen to a DNA strand before nucleotides can begin to be assembled into a new RNA strand?
The DNA has to be separated into two strands. Bonus Question?
400
What is a special type of RNA that is not mRNA, rRNA, or tRNA. Include the abbreviation as well
Micro RNA and the abbreviation is miRNA.
500
Compare/Contrast RNA & DNA with regards to composition
Both contain a phosphate group with a nitrogen base. They differ in the fact that RNA contains a single sugar ribose as opposed to deoxyribose.
