How did you know which bases to use when you transcribed the DNA sequence to mRNA codons?

In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and Uracil, while those in DNA are Adenine, Guanine, Cytosine and Thymine.
So the mRNA strand would be formed by matching the A in DNA with U in mRNA, T in DNA with A in mRNA, C in DNA with G in mRNA and G in DNA with C in mRNA.
I hope that helps!

Suppose the DNA sequence for the first message in part B began with TGT CGA instead of TGA CGA. Would the message change ?

What would the HIV viral sequence of AUCUU be converted to and by what enzyme?
The HIV virus is an RNA virus, so you know the sequence AUCUU is the RNA sequence. (You also know it is RNA because it contains uracil.) HIV is a retrovirus, so its RNA will be transcribed to DNA by the enzyme reverse transcriptase and then inserted into the host's genome. The RNA sequence of AUCUU would be transcribed to TAGTT.
How do you know if you are looking at a DNA or RNA sequence?
DNA sequences contain the nitrogen bases adenine, thymine, cytosine, and guanine. RNA sequences contain the nitrogen bases adenine, uracil, cytosine, and guanine. If the sequence contains thymine it is a DNA sequence if it contains uracil it is an RNA sequence.
How does the cell know which proteins to make from the DNA code?
Firstly, DNA is transcripted to mRNA, which is then translated by ribosomes into your polypeptide. Each set of 3 bases on the mRNA (codon) codes for a particular amino acid. However, there can be up to four codons, coding for a single amino acid. ie GCU, GCC, GCA and GCG all code for Alanine. Therefore, if you know the amino acid sequence, you can work backwards to mRNA and then to DNA, but you wouldn't be very accurate as you'd need to guess the codons.
Should you unlock your codons?
I have just done it. I would like to know what will happen from now on...
What type of bond holds one nitrogen base to its complementary base?
I Believe the answer is sequence of nitrogen bases. 70 Year old woman in 5th Grade , i think i know this.

One complete turn of the double helix of DNA contains 10 pairs of bases and is 3.4 nm long What is the approximate length of the DNA coding sequence of lysozyme a protein of 129 amino acids?
Well, we would have to know how many % of the coding sequence would be exons and introns, but let's ignore this and assume 100% of the sequence are exons;129 aminoacids = 129 codons = 129*3 nucleotides = 387 nucleotides.10 pairs of bases = 3,4 nm;387/10 = 38,738,7 * 3,4 = 131,58 nm.

Suppose you knew the makeup of specific proteins in a Cell - how would you determine the particular Dna sequences that coded for them?
This is done by and through the use of The Genetic Code.This is actually only partially possible because of the Situation that demands the creation of the term 'Wobble Base'.The implementation of The Genetic Code involves - simply - the [sequential][and consequential] string of Triplet Codons, as represented by the Dna sequence of Bases, being transcribed into messenger Rna which then is presented to the [endoplasmically embedded] Ribosomes; where each triplet codon is exactly represented by ONE amino acid.Whereas there are 64 triplet codons that exist, we need to represent only 20 animo acids - hence the wobble bases.
What tRNA know what amino acid is coded on the m RNA?
Every three bases on an mRNA molecule is known as a codon. The tRNA molecules have corresponding base pairs called an anticodon that will only pair up with the codons on mRNA. In this way mRNA specifies the amino acid that tRNA brings next in the sequence on the growing peptide chain.
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?
131*3=393 bases might be there on mRNA strand 3 codons of mRNA strand deduce an aminoacid of a protein, so here, mRNA strand bases are being asked.
What feature of DNA ensures that amino acids are linked in the correct order to synthesise pepsin?
The bases present, meaning the codons. They also have a start and stop codon to know what order the code starts and stops at.
What do codons code for in addition to amino acids?
"STOP"

The Human Genome Project can help genetic engineers produce human proteins because?
to produce a protein, geneticists must know the sequence of DNA bases that codes for the protein.
