What is the minimum number of DNA nucleotides?
Three
Three is the minimum number of nucleotides per codon needed to encode 20 amino acids.
How many nucleotides on a DNA strand are required to code for a protein of 300 amino acids?
Each codon stands for a specific amino acid, so if the message in mRNA is 900 nucleotides long, which corresponds to 300 codons, it will be translated into a chain of 300 amino acids.
How long is a DNA strand in nucleotides?
There are about 3 billion nucleotides in human DNA. The average length of a human nucleotide is 0.6 nanometers, or 0.0000000006 meters, so human DNA is about 1.8 meters (5 feet) long.
What is the minimum number of DNA bases required to code for the amino acids in this polypeptide?
It needs to be 50 or below to be a peptide.] 3 nucleotides determine 1 amino acid, so we get 153 nucleotides from that. However, we also need a start and a stop codon, which can but doesn’t have to produce the first and last amino acid, respectively.
How many nucleotides would be expected for a gene coding for a protein?
evolution: Gene mutations three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein.
What is the length of a DNA molecule?
Length of human DNA

| The World Book Encyclopedia . Chicago, World Book, 1999. | On the average, a single human chromosome consists of DNA molecule that is about 2 inches long. | 2 , 3 m |
How many amino acids would a DNA 12 nucleotides long encode?
Individual tRNAs carry each amino acid, each tRNA is specific for one amino acid only. This 12 nucleotide sequence encodes for 4 amino acids if it is an mRNA.
How many nucleotides does it take to encode 20 amino acids?
1. Three is the minimum number of nucleotides per codon needed to encode 20 amino acids. b. If a codon were two nucleotides, the set of all combinations could encode only 4×4 = 16 amino acids. c. With three nucleotides, the set of all combinations can encode (i.e. 64 different combinations of four nucleotides taken three at a time). 2.
How many nucleotides are there in a genetic code?
Overview for Genetic Code and Translation: Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases). The adaptor molecule for translation is tRNA.
How many base pairs of DNA are in the human genome?
The nuclear genome of a single human cell (i.e., the entire diploid complement) contains about 6.6 billion (6.6 × 10 9) base pairs of DNA. If synthesis at each replication fork occurs at an average rate of 50 nucleotides per second, all the DNA is replicated in 5 minutes.
What is the nucleotide triplet that encodes an amino acid?
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
