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 .

Molar Mass of hemoglobin is g/mol

Explanation:

As we know that

Where "P" signifies pressure, "V" signifies volume, "R" signifies gas constant, "T" signifies temperature and "n" signifies number of moles.

atm

K

Substituting the given values in above equation, we get -

moles of oxygen

Number of moles of hemoglobin is of moles of oxygen

moles

Molar mass of hemoglobin is equal to weight of hemoglobin divided by number of moles of hemoglobin

g/mol
