Flashcards in DNA and RNA Deck (18)
How many codons do you need for one amino acid
A sequence of three on an RNA strand
Copying of nucleic acid (DNA)
mRNA codons are interpreted by ribosomes. Amino acid codons compliment mRNA codons
What is the enzyme called that unzips DNA?
What is the codon? What is the anti-codon
Anti-codon: Amino acid
example: AAA (mRNA) UUU (Amino acids)
What is the job of RNA
To create proteins
What are the differences between DNA and RNA
DNA: Sugar is deoxyribose, double stranded, and A w/ T; G w/ C
RNA: Sugar is ribose, single stranded, Thymine is replaced with uracil, A w/ U; G w/ C
What type of strands do RNA and DNA have
RNA: single stranded
DNA: Double stranded
Instead of the base pair "A and T", what replaces what in RNA
"U" replaces "T"
what does RNA stand for
DNA makes protein (True or false)
False. RNA creates proteins
-Created in nucleus
-RNA polymerase binds to DNA and opens DNA into separates strands
-RNA polymerase uses one DNA strand to assemble the RNA molecule
-Thymine is replaced with uracil
- RNA BEING BUILT
Since DNA can't make proteins, what happens instead?
The instructions from the DNA are copied to be changed into RNA
What are the three types of RNA and what is theyre purpose?
-Messenger RNA: Carries copies of the DNA's instructions to the rest of the cell.
-Ribosome RNA: Makes up ribosomes, along with protein
-Transfer RNA: Uses mRNA to transfer amino acids from the cytoplasm to the ribosomes
The coded instructions on a DNA strand, controls production of protein. (3 bases on each strand with six total)
The making of protein
