Question

9. A sample of blood is put in a tube of water. Describe what happens using scientific terms

10. Draw a sequence of double-stranded DNA that would result in the transcription of the codons AUGCCCCCAUAG: How many amino acids would result from the sequence above?

12. What is the central dogma of molecular biology? Where does it occur (be specific)

Answer 1

Answer:

10).

a).

mRNA = 5’- AUGCCCCCAUAG – 3’

Double stranded DNA is as follows:

DNA template = 3’-TACGGGGGTATC-5’

DNA coding strand = 5’-ATGCCCCCATAG – 3’

b).

mRNA = 5’- AUGCCCCCAUAG – 3’

Amino acids = Met-Pro-Pro-STOP

Total of three amino acid length of peptide was produced from the mRNA.

12).

Central dogma:

DNA produces mRNA by transcription process. It occurs in nucleus

mRNA produces proteins by translation process. It occurs in ribosomes present in the cytoplasm.
