Rna primer constructed during dna replication needs to be replaced because rna differs from dna. it instead . 1. adenine, cytosine, uracil 2. adenine, guanine, thime

Correct 1. adenine, cytosine, uracil

RNA is a polymer that consists of ribose sugar and phosphate backbone. The four different types of nitrogenous bases found in the RNA are adenine, guanine, cytosine, and uracil.

Structurally DNA and RNA are similar, One major difference between DNA and RNA is that RNA consists of ribose sugar instead of deoxyribose sugar in DNA. Another difference is that RNA possess Uracil instead of thymine in DNA.

Hence, the correct answer would be adenine, cytosine, uracil .

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

the answer to this predicament is false, by friend, i had this on a quiz, and i got it wrong, so i learned it, cos i was gonna have it on a test, and i got it right
