how would you dtermine the particular DNA code that coded them?

Question

Suppose you knew the makeup of specific proteins in a cell. how would you determine the particular DNA code that coded for them?

Answer 1

DNA has 4 nitrogenous bases:

Adenine which ALWAYS pairs with Thymine

Guanine which ALWAYS pairs with Cytosine

On a DNA strand, these bases form triplet codes, which are complementary.

Top: AAG-GGA-TCC-CCC-GTC
Bottom: TTC-CCT-AGG-GGG-CAG

These codes are essential for protein development. Messenger RNA (mRNA) comes into the nucleus to pick up these particular codes on a particular segment of the DNA strand to make a particular kind of protein, let's say to break down fat in your brain, which is crucial, or else you would die (Tay-Sachs Syndrome).

So when the mRNA comes into the nucleus for transcription, the DNA strand opens up, and the DNA is copied. However, with RNA, THYMINE isn't available, so URACIL pairs with ADENINE.

DNA: AAG-GGA-TCC-CCC-GTC
mRNA: UUC-CCU-AGG-GGG-CAG

The mRNA leaves the nucleus and goes to the ribosome in the cytoplasm, which produces amino acids based on that particular chain that the mRNA brought.

Thus, this is why DNA is like a coded message!!

PROTEINS:

First of all, let AAA-GGG-CCC-UUU be our amino-acid chain. Hypothetical, but easy to do.

REMEMBER, only DNA has the base THYMINE. RNA and proteins have URACIL instead of thymine, so therefore, Uracil pairs with Adenine outside the nucleus (ie. DNA).

So, if AAA-GGG-CCC-UUU, their complementary bases are the DNA codes.

Protein: AAA-GGG-CCC-UUU
DNA: TTT-CCC-GGG-AAA

Now, for the long way...

Let's start with DNA first:

DNA: TTT-CCC-GGG-AAA

messenger RNA comes into the nucleus to copy that code, but uses uracil to pair up with adenine.

DNA: TTT-CCC-GGG-AAA
mRNA: AAA-GGG-CCC-UUU

mRNA takes its codes to the ribosome, where transfer RNA (tRNA) makes anti-codons:

mRNA: AAA-GGG-CCC-UUU
tRNA: UUU-CCC-GGG-AAA

amino acids that are complementary to the codons of the tRNA get attached, thus forming a protein chain

tRNA: UUU-CCC-GGG-AAA
Protein: AAA-GGG-CCC-UUU

Answer 2

You wouldn't know the exact DNA sequence just from the protein because many of the protein's parts (the amino acids) have several codons (sets of three bases) that call for them.

So you can start with the DNA code and work forward to figure out the protein, but you can't reliably start with the protein and work backward.

Answer 3

The cosmological data proves a deistic God. it really is the same as declaring The Universe is God. this isn't a own God that is the God that the atheists do not believe in. for this reason it has no relating atheism. regardless of if the DNA code is in step with and helps theism it isn't data of theism by technique of itself. extraterrestrial beings would have built it. the reality should be available. we do not recognize. The step from deism to theism remains a step taken in good faith.

Answer 4

Amino acid sequence.

Answer 5

this stuff is not easy, you have to have realy good eduaction to understand this

Answer 6

A match. You have to have a sample to "MATCH" it from .Are you worried ?
