GAUUACA

GATTACA

Transcription

2. The process by which the genetic code of DNA is copied into a strand of mRNA is:

  

translation

   

transformation

   

transcription

   

replication

Transcription

3. Both DNA and RNA:

contain uracil

DNA structure

4. Each combination of three nitrogen bases on a mRNA strand is called a/an:

Anticodon

   

Nucleic acid

Transcription

5. Unlike DNA, RNA contains:

a double strand

   

phosphates

   

uracil

Nucleic acid structure

6. In transcription, uracil will bond with:

9. Most of the time in a cell's life, it's DNA is in the form of:

  

Chromatin

   

Chromatids

   

Replicated chromosomes

   

Spindle fibers

10. Uracil is a nitrogen base that pairs with adenine. Using this information, one could conclude that uracil is a:

  

Purine

   

Pyrimidine

   

Neither a purine or pyrimidine

   

Not enough information

11. a nucleotide does not consist of a:

  

polymerase

   

5-carbon sugar

   

phosphate group

   

nitrogen base

12. The genetic code in DNA of an individual depends on the sequence (order) of:

  

nucleotides

   

purines only

   

phosphates

   

sugars

13. Before a cell divides, it must duplicate its DNA in a process known as:

  

translation

   

transformation

   

transcription

   

replication

14. The basic unit (building block) of a protein is a (an):

  

carbohydrate

   

amino acid

   

lipid

   

hydrogen bond

15. Unlike DNA, RNA contains:

  

deoxyribose

   

a double strand

   

phosphates

   

uracil

16. The structure of DNA was first documented in:

  

1945

   

1953

   

1956

   

1962

17. In DNA replication, the new molecules produced are:

  

of unequal length

   

both assembled in the same direction

   

built with purines as the backbone

   

assembled in opposite directions

DNA replication

18. The "backbone" of DNA is composed of:

  

ribose and phosphates

   

deoxyribose and phosphates

   

ribose and uracil

   

deoxyribose and thymine

DNA structure

19. RNA differs from DNA in which of the following ways?

  

RNA is single-stranded

   

RNA contains ribose

   

RNA does not contain thymine

   

All of the above

DNA structure

20. Which of the following is NOT required for the transcription process itself?

  

RNA polymerase

   

DNA

   

uracil-containing nucleotides

   

ribosomes

Explanation / Answer

1) GAUUACA is the complementary strand of CTAATGT.

2) transcription is the process by which DNA stand is copied into mRNA strand.

3) Both dna and rna contains adeneiyand Guanine Purines.

4) Combination of three nitrogenous base is called a codon.
