In RNA A is always bonded to?
In RNA, despite the DNA, the two couples of bases matching are G-C (as the DNA) and A-U (A-T in DNA). G-C is a strong 3-H bond match, while both A-T and A-U are weak 2-H bond matchs A = adenine C = cytosine T = tymine G = guanine U = uracyl
When are 2 amino acids linked by a peptide bond?
two tRNAs pair with neighboring codons on an mRNA transcript
What is specific base pairing?
a pair of nitrogenous bases,consisting of a purine linked by hydrozen bonds to a pyrimidine that connects the complementary strands . the base pair are adenine,thymine,cytosine & guanine in DNA & uracil in place of thymine in RNA.
What make up the rugs of the DNA molecule?
two nitrogenous bases linked together in the middle
How would you tell which one was DNA and which was RNA if you were looking at two polymer chains?
There are some significant differences between DNA and RNA which may help you to identify which one is which. For example, DNA does not have an oxygen on it's 2' carbon in the deoxyribose sugar whereas RNA does. Furthermore, if you are able to see the organic bases, this may help you also. DNA has the bases ATCG. In RNA however, the T (thymine) is replaced with U (uracil) and so the bases in an RNA strand are AUCG. In simple words, if there is an oxygen on the 2nd carbon of the sugar ---> RNA If there is a U base ---> RNA.
Two of the four nitrogen bases linked together in each double strand of DNA?
RNA
Is uracil a nitrogenous base?
Yes, the two nitrogen atoms in urcil function as hydrogen bond acceptors, so the molecule is basic.
How many strands of nitrogenous bases does an RNA molecule have?
two
What are the two major groups of nitrogenous bases in RNA and DNA?
Purines and Pyrimidines

Which type of Rna can only bond to one specific type of amino acid?
transfer RNA. (tRNA) it "picks up" an amino acid at the top and the two are connected by a hydrogen bond.
How are the four bases of DNA linked?
Bases in DNA are linked through hydrogen bonds. There are two hydrogen bonds between Adenine and Thymine There are three hydrogen bonds between Guanine and Cytosine
When two amino acids are linked together to form a peptide bond what is removed?
A water molecule
What is specific base pairing?
a pair of nitrogenous bases,consisting of a purine linked by hydrozen bonds to a pyrimidine that connects the complementary strands . the base pair are adenine,thymine,cytosine & guanine in DNA & uracil in place of thymine in RNA.
Bases of DNA are linked together by intermolecular forces are called?
The two strands of DNA are linked together by hydrogen bonds which occur between the nitrogen bases opposite one another along the molecule.
What make up the rugs of the DNA molecule?
two nitrogenous bases linked together in the middle
