Nucleic Acids Flashcards
What are the types of Nucleic acids?
Deoxyribonucleic acid and Ribonucleic acid
What is used by the nucleic acid?
Contains instructions for protein synthesises and other gene products
Nucleic acids are the polymers, then what are the monomers?
Nucleotides
The carbons in nucleotide goes clockwise, correct?
True
How are nucleic acids formed?
When the nucleotides are bonded via condensation reaction
What is stronger phosphodiester bond or hydrogen bond?
phosphodiester bond
How are the two polynucleotide strands in DNA kept together?
Hydrogen bonds
How can knowing complementary base pairs be useful?
-Can predict the nucleotide sequence for the other strand
-Can determine the percentage of allll the other bases as long as you have one bases percentage
Differences between DNA and RNA the only correct ones
-Thymine is replaces with Uracil in RNA
-RNA has ribose sugar not Deoxyribose sugar
How is ribose sugar diffrent to deoxyribose sugar?
It has more oxygen
Is DNA always found in the nucleus? If not then where else
No, mitchondria and chloroplast have it aswell.
What is RNA?
Ribonucleic acid (RNA) is a single stranded
nucleic acid chain made up of nucleotides.
What are the three types of RNA
Transfer RNA
rRNA
mRNA
What direction does RNA/DNA polymerase run down the strand ALWAYS
5’-3’ Direction
What direction is nucleotides being added to the growing strand by RNA polymerase?
3’-5’ Direction
