What else can I help you with?
The genetic code is universal but what does this mean?
this means that the same genetic code that is used in humans is used in all other types of organisms as well. anything from animals to plants to bacteria uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide. remember that the genetic code is also degenerate- each codon only codes for one amino acid, but there can be several different codons that call for the same amino acid.
What about the degenracy of genetic code?
Type your answer here... the degenracy of code means there are more than one codons for one amino acid.The opposite of it ie.non-degeneracy of codon means ther is only one codon for one amino acid.
The genetic code is said to be universal because a codon represents the same?
The genetic code is said to be universal because a codon representsthe same amino acid in almost all organisms.
What are the Feature of genetic code?
it is made of a sequence of nucleotides:in DNA or RNA, these nucleotides are adenine, guanine, cytosine, and uracil where it determines the specific amino acid sequence in the proteins,but is the biochemical of heredity and nearly universal in all organisms... DNA transfers and forms a code.
If two references are having same hashcodes is that mean those two are refering to same object?
Possibly. It could also mean that the two references are referring to two different Objects, which contain the same data.
How do birds and dogs both use DNA as instruction for building their bodies even though they are very different organisms?
Their DNA has the same nucleotide bases, but in different patterns. DNA forms the building blocks of all living things, regardless of species.
What are the best nucleotide triplets that best represent a codon?
The best nucleotide triplets that represent a codon are Adenosine, Cytosine, Guanine, and Uracil (A, C, G, and U). These nucleotides form RNA molecules, which are used during protein synthesis to encode the sequence of amino acids in a protein. Each triplet of nucleotides, or codon, corresponds to a specific amino acid or a signal to start or stop protein synthesis.
Could a mutation affect phenotype?
Yes, a mutation can occur without affecting the phenotype at all. For example, a point mutation may change a nucleotide in a codon, but sometimes, the codon can still code the same amino acid, so the mRNA strand can still make the same protein.
How many MRNA nucleotides make up a codon?
An mRNA codon is 3 bases long and can contain 4 different bases (A, U, C and G).Therefore there are 64 (4 X 4 X 4) different combinations.Many of these will code for the same amino acid. For example; UCA, UCU, UCC and UCG all code for the amino acid Serine.
Are five different types of nucleotide bases found in living things. Which is an accurate comparison of the bases found in bears as opposed to the bases found in raccoons?
They have the same bases in different orders
What do 3 nitrogenous bases make up?
A nucleotide is the basic building block of DNA and RNA.It consists of a sugar(deoxyribose in the case of DNA and ribose in the case of RNA), a phosphate group and a base (either adenine, guanine, cytosine or thymine)A nucleotide is the basic building block of DNA and RNA.It consists of a sugar(deoxyribose in the case of DNA and ribose in the case of RNA), a phosphate group and a base (either adenine, guanine, cytosine or thymine)A nucleotide is the basic building block of DNA and RNA.It consists of a sugar(deoxyribose in the case of DNA and ribose in the case of RNA), a phosphate group and a base (either adenine, guanine, cytosine or thymine)
How do birds and dogs have the same DNA?
Their DNA has the same nucleotide bases, but in different patterns. DNA forms the building blocks of all living things, regardless of species.
How might one missing nucleotide or the insertion of one additional nucleotide in a DNA strand alter the formation of the translated protein?
Deletion of just one nucleotide in a protein-coding part of a gene will cause a "frameshift mutation." Since the nucleotides are read in groups of three (codons) along the gene, the groupings will change and the protein that results is likely to be completely different.
How do birds and dogs both use DNA an instructions for building their bodies even though they are very different organism?
Their DNA has the same nucleotide bases, but in different patterns. DNA forms the building blocks of all living things, regardless of species.
Which mutation would not change the remainder of the reading frame of a gene sequence that follows the mutation?
A silent mutation, where a nucleotide substitution results in a codon that codes for the same amino acid, would not change the remainder of the reading frame of a gene sequence. This is because the amino acid sequence produced by the altered codon remains the same.
What determines how many amino acids is in a polypeptide?
When a gene is transcribed there is a sequence of RNA bases that was copied from the DNA sequence. The RNA sequence can be exactly the same as the DNA or can be modified more in higher organisms by removing the introns if any. Three RNA bases is a codon. Each codon signifies an amino acid. There is an initiation codon and a terminal codon. So the amino acid sequence is determined by the sequence (multiple of 3 RNA bases) of codons between the initiation codon and termination codon.
How many bases code for a triplet?
There are four DNA nucleotides, each with one of the four nitrogen bases (adenine, thymine, cytosine, and guanine). The first letter of each of these four bases is often used to symbolize the respective nucleotide (A for adenine nucleotide, for example). In RNA the bases are the same except that when pairing of bases occurs in RNA, uracil (instead of thymine) pairs with adenine.
