RNA Structure and Function

The RNA nucleotide is composed of which among the following

• Phospholipids + nitrogen base + ribose sugar

• Sphingosine + nitrogen base + ribose sugar

• Phosphate + ribose sugar + nitrogen base

• None of the above

The following nitrogen pair in RNA is correct except

• Adenine = Thymine

• Adenine = Uracil

• Guanine = Cytosine

• None of the above

The following statement is true to RNA molecule except:

• RNA molecule are single stranded

• They are made by "copying" a segments of a single stranded DNA

• It uses uracil instead of thymine to bond with adenine

• None of the above

Check the statement and determine if its true or false:

An RNA molecule leaves the nucleus to go to the ribosomes in the cytoplasm

• TRUE

• FALSE

• NOT SURE

• None of the above

It is a copy of gene sequence from one DNA strand of a DNA molecule, when complete it leaves the nucleus and goes to the ribosome in the cytoplasm

• RNA

• DNA

• mRNA

• tRNA

Structural molecule that is a part of a ribosome structure. It assists in the production of proteins during the translation process

• RNA

• rRNA

• mRNA

• tRNA

It assists in the production of proteins by transferring amino acids to the ribosomes when needed.

• RNA

• rRNA

• mRNA

• tRNA

The RNA nucleotide is very similar with the DNA nucleotide

• TRUE

• FALSE

• Neither

• Either

The sugar in RNA and DNA are different, the RNA contains deoxyribose and the DNA contains ribose sugar

• TRUE

• FALSE

• Neither

• Either

The sugar joins the phosphate group and the base group, thus the sugar has an adhesive portion.

• TRUE

• FALSE

• Neither

• Either
