How many nitrogen bases make-up a codon?
Three nitrogenous bases make up a single codon.
How do the nitrogen bases along a gene serve as a genetic code?
Nitrogen bases along a gene form codons, which are three-base sequences that code for specific amino acids during protein synthesis. This sequence of codons provides the genetic instructions that determine the sequence of amino acids in a protein. The genetic code is universal, meaning that the same codons code for the same amino acids in nearly all organisms.
Why is the sequence of nitrogenous bases in DNA important for genetic information and protein synthesis?
The sequence of nitrogenous bases in DNA is important for genetic information and protein synthesis because it determines the specific instructions for making proteins. Each sequence of bases codes for a specific amino acid, which are the building blocks of proteins. The order of these bases in DNA determines the order of amino acids in a protein, ultimately influencing the structure and function of the protein.
What is a codon made of?
A codon is made up of a sequence of three nucleotides. In DNA, a nucleotide contains the sugar deoxyribose, a phosphate group, and one of four nitrogen bases; adenine, thymine, guanine, and cytosine. In RNA, a nucleotide contains the sugar ribose, a phosphate group, and one of four nitrogen bases; adenine, uracil, guanine, and cytosine. Each codon represents an amino acid, or a start or stop signal.
How many DNA bases are read at a time?
In protein synthesis, three DNA bases, known as a codon, are read at a time by the ribosome. Each codon corresponds to a specific amino acid in the process of translating the genetic information into a protein.
Absence of which nitrogen bases would prevent protein synthesis?
The absence of adenine, guanine, cytosine, and uracil would prevent protein synthesis. These nitrogenous bases are essential for the proper functioning of DNA and mRNA in the process of transcription and translation. Without them, the genetic code cannot be properly read and protein synthesis would be halted.
A region of tRNA that consists of three bases complimentary to the codon of RNA?
Anticodon. This is the region of transfer RNA (tRNA) that pairs with the complementary codon on messenger RNA (mRNA) during protein synthesis.
What 4 bases are used in protein synthesis?
In DNA, the 4 bases are guanine, cytesine, thymine and adenine. In RNA, also used in protein synthesis, instead of adenine, there is urasil
The weak chemical bonds importat in holding the DNA double helix together is the?
The two strands of DNA nucleotides are held together by hydrogen bonds between complimentary nitrogen bases. Adenine pairs with guanine and cytosine pairs with thymine. When it is time for a cell to reproduce, and during protein synthesis, an enzyme called helicase breaks the hydrogen bonds between the two strands. This way DNA can be replicated in preparation for cell reproduction or it can be used as a template for protein synthesis.

Does protein synthesis have three continuous bases?
During protein synthesis, three continuous bases on a messenger RNA (mRNA) molecule, known as a codon, encode different amino acids. Codons on the mRNA are translated into the amino acid sequence of a protein by the ribosome.
How is the nitrogen base sequence of a gene related to the structure of a protein?
The sequence of nitrogenous bases (A, T, G and C) forms a code for the sequence of amino acids in a protein. The code is a triplet code. This means that three bases code for one amino acid. So, the order of the bases in a gene determines the order of the amino acids in a protein.
What are the 4 bases used in protein synthesis?
The four bases used in protein synthesis are adenine (A), guanine (G), cytosine (C), and uracil (U). In DNA, uracil is replaced by thymine (T). These bases pair up in specific combinations during transcription and translation to form the genetic code that determines the sequence of amino acids in a protein.
What does trna uses to match to the mrna?
tRNA contains an anticodon which is a sequence of three nitrogen bases that is complimentary to a particular mRNA codon.
