Rather than what came first, the chicken of the egg; what came first, DNA or Protein?

Answer 1

DNA

Answer 2

Both. DNA needs protien and Protein Needs DNA if there is to be a synthesis to take place.

DNA-RNA-Protein
Introduction

DNA carries the genetic information of a cell and consists of thousands of genes. Each gene serves as a recipe on how to build a protein molecule. Proteins perform important tasks for the cell functions or serve as building blocks. The flow of information from the genes determines the protein composition and thereby the functions of the cell.

The DNA is situated in the nucleus, organized into chromosomes. Every cell must contain the genetic information and the DNA is therefore duplicated before a cell divides (replication). When proteins are needed, the corresponding genes are transcribed into RNA (transcription). The RNA is first processed so that non-coding parts are removed (processing) and is then transported out of the nucleus (transport). Outside the nucleus, the proteins are built based upon the code in the RNA (translation).

The document has two levels, basic and advanced. This page is an introduction to both levels. You start at the basic level, then you can advance if you want more and deeper information.

Answer 3

First to design a chicken a plan is required. The plan would require to set a program how the chicken is to function and reproduce.
However ,in order for a chicken to reproduce two mechanisms must be set. The first is to Create a Rooster and out of the rooster a Hen must be created. The Rooster must have a sperm with an apropriate Dna. The Hen must produce an egg with the apropriate Dna. The rooster must fertilize the egg. Out of the firtilized egg after incubation by the mother a new chick would come to life.

Its a very simple mechanism. I dont quite Understancd what is so difficult to figure out how Eggs are born.

Answer 4

The first self-replicating molecule was probably RNA. RNA carries genetic information and it can replicate itself without any proteins. Then, RNA started assembling amino acids into proteins. Then DNA developed as a more stable form of RNA which could hold lots more information.

As for the chicken and egg - the egg came first. Although the first egg was not a chicken egg.

Answer 5

When your in your mom tummy you get the protein from the food you eat. Enzymes then turn that protein into amino acid to turn it back to protein (but in the way the cell need it to be ). Scientifically, there is no chicken and egg matter. Because it's just not too much to explain

Answer 6

Dna of course,cause it's the first order from the kernel,after it ARN messenger transmit it to another place translate the first information but the DNA at first is a protein

Answer 7

Not real sure but I think that DNA is made up of Protein, so I would say Protein came first.

Answer 8

it puzzles me why people who have so little knowledge of biology that they would say DNA is made up of protein would even answer a question like this

why confuse this question answerer??? seriously. its annoying and not only that its misleading they may be genuinly confused and needing an answer

Protein is made up amino acids
amino acids are made up of nucleotides (3 per amino acid)
nucleotides are part of DNA

therefore...DNA came first
you cannot have protein without DNA
you can have DNA without protein
protein is made up of DNA
etc etc

Answer 9

I'd argue that protein came first... a specific combination of amino acids. Can't have life without amino acids ... but yeah, it's a bit of a chicken and egg question. Don't quote me on this though. I'm not 100% sure.

Answer 10

I would have said DNA but thats just my opinion. Its quite possible that proteins existing before DNA but they would have been very simple and there would have been very little of it

Answer 11

Protein sine it is the component of DNA
