What else can I help you with?
A protein contains 131 amino acids How many bases will there be on the mRNA strand corresponding to these amino acids and how do you know?
There would be 393 bases on the mRNA strand corresponding to 131 amino acids, as each amino acid is coded for by a sequence of three bases (1 codon). By multiplying the number of amino acids by 3, you can determine the total number of bases required to encode the protein sequence on mRNA.
How many codons are present on the mRNA strand?
There are 6 codon here. Look at the letters and put them into threes. Those three are called codons. Each codes for one amino acid and all of these is a string of threes which will make a small protein.
How many adenine bases would there be in a DNA molecule of 40 base pairs with 15 cytosine bases?
Since there are 15 cytosine bases, we can conclude that there are 15 guanine bases. That gives us a total of 30 bases, subtract that from 40 and you have 10 bases left. So then there are 5 adenine bases because there are also 5 more thymine bases.
How many bases are found in anticodon?
There are three bases in the anticodon region of a transfer RNA (tRNA) molecule. These bases are complementary to the codon sequence on messenger RNA (mRNA) during protein synthesis to ensure the correct amino acid is incorporated into the growing polypeptide chain.
How many bases on a strand of mRNA code for one amino acid?
3 nucleotides
Each tRNA molecule contains three bases called?
Each tRNA molecule contains three bases called an anticodon. The tRNA anticodons are complementary to specific mRNA codons. This is how the amino acids are placed in the proper order on the ribosome.

There would be 393 bases on the mRNA strand corresponding to 131 amino acids, as each amino acid is coded for by a sequence of three bases (1 codon). By multiplying the number of amino acids by 3, you can determine the total number of bases required to encode the protein sequence on mRNA.
How many nucleotides would it take to construct the mRNA coding strand of the β-subunit of the hemoglobin A molecule?
441 nucleotides
How many bases are needed to specify an mRNA codon?
3 bases are needed to specify an mRNA codon.
If there are three amino acids how many bases would there be on the M RNA to make these three?
Each amino acid is encoded by a set of three nucleotide bases in mRNA, known as a codon. Therefore, to encode three amino acids, there would need to be a total of nine nucleotide bases in the mRNA (3 amino acids x 3 bases per amino acid = 9 bases).
If an mRNA is made up of 60 bases how many codons does it contain and how many amino acid does it code for?
A codon is exactly three bases long, so an mRNA strand with 60 bases would contain 20 codons. The first codon will encode for methionine (this is called the "start" codon) and the last codon will be a "stop" codon, which does not encode for an amino acid. Thus, an mRNA strand of 60 bases will code for 19 amino acids. Keep in mind, it is possible for a stop codon to be anywhere on the mRNA strand, and when a stop codon reaches the ribosome, translation must stop. For example, if an mRNA strand contained 30 codons, and the 15th were a stop codon, the mRNA would only code for 14 amino acids and then be done. The other 15 codons would go untranslated.
How many codons are present on the mRNA strand?
There are 6 codon here. Look at the letters and put them into threes. Those three are called codons. Each codes for one amino acid and all of these is a string of threes which will make a small protein.
How many bases are in an anticondon?
An anticodon is a sequence of three nucleotide bases on a transfer RNA (tRNA) molecule that pairs with a complementary codon on mRNA during protein synthesis. Therefore, an anticodon consists of three bases.
How many adenine bases would there be in a DNA molecule of 40 base pairs with 15 cytosine bases?
Since there are 15 cytosine bases, we can conclude that there are 15 guanine bases. That gives us a total of 30 bases, subtract that from 40 and you have 10 bases left. So then there are 5 adenine bases because there are also 5 more thymine bases.
What type of RNA is formed during transcription?
In Translation, rRNA, tRNA, and mRNA are used. The mRNA strand of codons (3 nucleotide bases) enters the ribosome where the rRNA will "read it" (it is made up of rRNA). tRNAs are floating in the cell carrying the anticodon's specified amino acid. When the rRNA "sees" which codon is on the mRNA strand, the tRNA's anticodon (complementary nucleotide bases) binds to the A site in the ribosome to start creating the polypeptide chain.
How many bases are found in anticodon?
There are three bases in the anticodon region of a transfer RNA (tRNA) molecule. These bases are complementary to the codon sequence on messenger RNA (mRNA) during protein synthesis to ensure the correct amino acid is incorporated into the growing polypeptide chain.
How many bases on a strand of mRNA code for one amino acid?
