Dna replication assignment
instructions: for this assignment, you will replicate dna to make a complimentary strand of dna. then transcribe the complimentary dna sequence into mrna. next, translate the mrna molecule into the codes for specific amino acids using the amino acid chart on the last page. lastly, address the reflection questions.
dna replication:
replicate the following strand of dna:
original dna a t g a a c c a t t c a g t a t g g
complimentary dna
transcription:
transcribe the dna to make an mrna molecule
complimentary dna
mrna molecule
translation:
translate the mrna into the corresponding amino acids.
mrna molecule
amino acid
can anyone with this? i don't understand it.
using the dna sequence provided, determine the amino acids.
original dna a t g g g t c t a g c g a a a g a t
complimentary dna
mrna molecule
amino acid

The correct answer will be:

Case I:

Original DNA:                                 ATG AAC CAT TCA GTA TGG

Complimentary DNA:                     TAC TTG GCA AGT CAT ACC

Transcript mRNA molecule:          AUG AAC CGU UCA GUA UGG

Translated sequence:                    Met- Asn - Arg - Ser - Val-  Trp

Case II:

Original DNA:                                   ATG  GGT   CTA  GCG  AAA  GAT

Complimentary DNA:                     TAC  CCA  GAT  CGC  TTT   CTA

Transcript mRNA molecule:           AUG  GGU CUA  GCG  AAA  GAU

Translated sequence:                     Met  -Gly-    Leu-   Ala-  Lys -   Asp

Explanation:

DNA replication is a process which produces a replica or exact copy of the DNA molecule by using one strand of the existing DNA as a template. The new strand is formed using Chargaff rule which states that purine binds pyrimidine that is adenine(A) will bind to thymine (T) and guanine (G) will bind to cytosine (C).

Transcription is a process which produces an mRNA molecule from one strand of DNA molecule. The mRNA acts as a messenger molecule which is formed with the same Chargaff rule except for a different nitrogenous base  "uracil". In mRNA uracil (U) will bind complementarily to adenine (A) instead of thymine.

The translation is a process which synthesizes the protein by reading the bases of mRNA in the triplets called 'codons". These codons code for a specific amino acid which bond to each other via peptide bond and form protein.
