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.
In RNA a string of 3 bases codes for each amino acid. What is the string of bases called?
a condon
What is a sequence of 3 n-bases in a row of trna called?
The sequence of three nitrogen bases on tRNA is called an anticodon. Refer to the related link below for an illustration.
What is a set of 3 nitrogenous bases in rna called?
A set of three bases in an RNA molecule is called a codon. And one codon codes for one amino acid.
Many RNA molecules from eukaryotic genes have sections called?
if i understand your question right, polymerase is my guess

Convert the following DNA sequence into its RNA equivalent and then using the genetic code convert that RNA sequence into the amino acid sequence 5tacttcttcaagact-3?
DNA Sequence = 5tacttcttcaagact-3 RNA Sequence = 3'-AUGAAGAAGUUCUGA-5'You just switch 5' and 3'T becomes AA becomes UC becomes GG becomes CThere should be no Ts in an RNA sequence.
In RNA a string of 3 bases codes for each amino acid. What is the string of bases called?
a condon
The direction of synthesis of an RNA transcript is?
transcription:"the first step in protein synthesis, a sequence of nucleotide bases becomes exposed in an unwound region of a DNA strand. That sequence acts as a template upon which a single strand of RNA - a transcript - is synthesized from free nucleotides."The synthesis of an RNA molecule from the DNA template strand is called transcription.

The sequence of three nitrogen bases on tRNA is called an anticodon. Refer to the related link below for an illustration.
What are the bases on the mRNA strands are called?
A 3-base sequence of nitrogen bases on a molecule of mRNA is called a codon.
What is a set of 3 nitrogenous bases in rna called?
A set of three bases in an RNA molecule is called a codon. And one codon codes for one amino acid.
How does transcription end?
Transcription ends once the a termination sequence is reached. The sequence depends on which polymerase is being used and if the organism is a eukaryote or prokaryote. In Eukaryotes when RNA polymerase 1 is used the termination sequence is an 18 nucleotide long sequence. For RNA polymerase 3 the termination sequence is a short sequence of Uricils but the hairpin loop is not formed as it is in prokaryotes. For RNA polymerase 2 transcription is terminated and cleavage takes place 10-35 nucleotides downstream of the AAUAA sequence. For prokaryotes, termination can occur 2 ways. Termination can occur once the termination sequence is reached or using a protein called Rho factor. For termination without Rho factor, the termination sequence is short and rich in Guanines and Cytosines followed by many Uricils in a row. A-U bonds are weaker than G-C bonds, the string of U-A bonds are easily broken and release the RNA strand Using a Rho factor, once the Terminal sequence is reached, the Rho factor binds to a sequence 50-90 bases long and unwinds the DNA from the RNA , moving towards the 3' end, releasing the RNA
What are the 3 nitrogen bases in transfer rna that pair with bases a-g-u in messenger RNA?
adenine guanine and thymine
Many RNA molecules from eukaryotic genes have sections called?

If the base sequence of the DNA is gtcaggatc what would be the corresponding base sequence of the messenger rna?
Wrong. UAC is the complimentary base sequence on the mRNA strand. RNA does not use the T nucleotide don u think if it should be written like CAU coz rna polymerase reads 3 to 5 and gives 5 to 3
How does DNA template dictate the sequence of the RNA produced?
During transcription the DNA double helix is separated into two individual strands. Each strand may serve as a template for RNA polymerase, which travels along the DNA structure in a 3' to 5' direction. As it progresses down the strand, RNA polymerase synthesizes a pre-messenger RNA strand that is complementary to the sequence on the DNA template. For example if the DNA sequence on the template was 5' ATACA 3', then the pre mRNA sequence synthesized would be 3' UAUGU 5'. (Remember, RNA synthesis utilizes the nucleotide uracil instead of thyamine).
