Is it possible for 2 different DNA sequences to code for the same amino acid?

So there are 4 DNA molecules--thynine, guanine, cytosine and adenine (usually people just say T, G, C and A). These molecules can be arranged into different chains, all forming different combinations of letters. The molecules actually code for these things called amino acids, and there are 22 essential amino acids in humans. And then, these amino acids are arranged in different orders and combinations to make proteins.
It takes 3 DNA molecules to give instructions to make one amino acid. So first you have 4 different molecules that can make different combinations of 3, these will then give you different combinations of the 22 different amino acids, and random numbers and combinations of the amino acids can be arranged in different shapes, which results in different proteins.
So basically, it's just a lot levels of organization, and different DNA sequences will end up making the protein combinations all different.

∙ 13y agoPotentially, yes.
A single amino acid can have multiple codons. For example, both the codons UAU and UAC code for tyrosine. Francis Crick first described this as "wobble."
So you can see that two genes with slightly different bases can code for the same sequence of amino acids. If both genes are identical except for one changed base pair, the chances that the resulting polypeptide will be the same for both isn't particularly high, but there is still a chance. The chances decrease with every base pair substitution.
This has implications in mutations, as a point mutation may or may not change the protein in translation. If it doesn't due to wobble, the mutation is said to be "silent."

∙ 10y agoyes. there is 64 possible codons and 20 amino acids. up to 4 codons can code for the same amino acid

How can amino acid sequences be used to identify the source of a virus?
Amino acid sequences can identify the source of a virus by determining which class the virus belongs to. It can also tell the type of nucleic acid.
What techniques uses the amino acid sequences of polypeptides to predict a protein's three-dimensional structure?
Bioinformatics
Is DNA an amino acid that encodes protein sequences?
No, DNA is not an amino acid. DNA is a nucleic acid composed of two chains of nucleotides. The sequence of nucleotides encodes for amino acids (almost every triplet of nucleotides encodes for some amino acid). The amino acids in turn build proteins. Please see the related link for more information.
What is DNA condon?
Condon has 3 bases sequences which three consecutive nucleotide specify a single amino acid that is to be added to the polypptide.
The 20 different amino acids found in polypeptides exhibit different chemical and physical properties because of different?
Amino acids exhibit different chemical and physical properties because of their R groups. An amino acid is asymmetric, meaning that it is a carbon bound to 4 different elements. Three out of the four are the same in every amino acid. These three are: an amino group, a Hydrogen, and a carboxyl group (otherwise known as an acid). Hence the name Amino Acid. The 4th grouping is called the R group, and it is different for every amino acid. This R group determines the shape of the amino acids and the shape determines function.

Which tells you more about a protein its amino acid sequences or composition?
i'd go with the amino acid sequences... they are, after all, the second genetic code, meaning they are the blueprint for the function of the amino acid.

What property of different sigma factors allows them to bind to different promoters?
different amino acid sequences resulting in different spatial arrangements of chemical groups
What does an amino acid table show?
Amino acid tables are used to translate mRNA codons into amino acid sequences. They also tell whem mRNA codons produce stops.
What is the effect of acid on protein?
There are twenty different Amino Acids that comprise proteins. The varying combinations and sequences of the Amino Acids produces different proteins.
Two proteins in the same cell perform different functions. this is because the two proteins are composed of?
Different sequences of amino acids and possibly different numbers.

What monomer makes up protein?
Amino acid monomers make up a polypeptide chain which folds into it's particular shape, based on amino acid sequences, to make a protein
Instructions for assembling amino acids into proteins?
Proteins are made from amino acids, there are different types of proteins in our body ane the order of the amino acids determines the type of amino acid cus it sure helped me :)
