I have attached the picture to help answer the next two question. Thanks

Using the DNA sequence TCAGGA, the dipeptide formed is
a) serine, glycine
b) threonine, glycine
c) serine, proline
d) threonine, proline

Some Amino Acids
1) Aspartate
2) Cysteine
3) Glutamate
4) Histidine
5) Leucine
6) Phenylalanine
7) Proline
8) Tryptophan
 
Numerical Response
Provive the correct sequence of numbers that represent the amino acids coded by the DNA nitrogen-base sequence shown below. Read the code beginning at the left.

-G-G-T-G-G-G-C-T-A-A-C-A-

First Question:
To do this, you simply have to transcribe from DNA to mRNA. And then you translate the mRNA tiplet code to the corresponding amino acid from the chart:

TCA GGA is transcribed to AGU CCU
AGU CCU is translated to: Serine, Proline

So the answer is C.

Second Question:
Just like the first question, we first do a transcription from the DNA template, and then do a translation from the mRNA triplets.

GGT GGG CTA ACA is transcribed to CCA CCC GAU UGU
CCA CCC GAU UGU is translated to:  Proline, Proline, Aspartate, Cysteine

So the answer is 7,7,1,2
