Which molecule determines the sequence of amino acids in a protein?
Information on a coding sequence of DNA is transferred into what molecules?
How does the sequence of DNA affect the function of a protein?
The sequence of nucleotides in DNA molecule is equivalent and is closely related to an amino acid sequence in the protein molecule. If for any reason the sequence of DNA nucleotides changes it will be reflected in amino acid sequence in the protein. Moreover, the correct sequence of amino acid in the protein will form the correct three-dimensional structure, or tertiary structure, that will confer the biological activity to protein. If a wrong amino acid is translated from a mutated gene in the DNA could change the spatial structure of the protein and therefore modify or erase its biological function.
The sequence of amino acids that makes up a protein molecule in the body are determined by?

Why is transcription and translation important?
Transcription and translation are part of the whole process called "The Protein Synthesis". Transcription is the process where the "genetic information" from DNA is copied to a single-strand molecule called RNA. The sequence of nucleotides carried by RNA molecule will be "read" during Translation process in order to translate it from nucleotide sequence into an amino acid sequence. In other words, from a nucleic acid molecule into a protein molecule.

How does DNA direct the making of proteins?
First of all, we should think in the making of proteins, or protein synthesis, as a process divided into very defined steps or stages. The first stage starts with the DNA. This outstanding molecule keeps the "biological information" within it, as we know, the genes. In general terms, a gene can be defined as a particular sequence of nucleotides with a defined length. This gene or sequence has to be "copied" into a molecule called messenger RNA. or mRNA, in a process known as transcription. mRNA molecule will serve as "template" for the new protein molecule that is going to be built. The sequence of nucleotides, every three of them, called "codons", will guide the formation of the new protein molecule in a process called "translation". In resume, DNA starts the making of a protein molecule from its nucleotide sequence that will be translated into an amino acid sequence, the monomers of a protein molecule.
The molecule that stores the information about the order of amino acids in a protein is?
How would the amino acid sequence produced by the mutant strand compare to the amino acid sequence produced by series 1?
How can DNA be synthesized to proteins when it is contained in the nucleus?
DNA, or deoxyribonucleic acid, is a molecule of heredity that stores information in the sequence of its subunit molecules called nucleotides. The sequence of these bases, like binary code for a computer, store information that codes for proteins on our bodies. Segments of DNA are called genes, and code for one protein. These segments of DNA are copied into another nucleic acid molecule called mRNA in a process known as transcription. mRNA is a single stranded molecules that is able to leave the nucleus and travel into the cytoplasm. In the cytoplasm, a ribosome is formed around the mRNA molecule. During translation, the mRNA molecule is read every three letters, which are called codons and stand for one amino acid. tRNA molecules carry amino acids and attach to specific three-base codons. The chain of amino acids is formed by peptide bonds between amino acids on subsequent codons. Eventually, a protein chain is created based on the information that was stored in the sequence of nucleotides in the original DNA. SHORT ANSWER: DNA does not leave the nucleus, but the mRNA molecule makes a copy of the DNA sequence and is able to take that out of the nucleus to a ribosome to make a protein.
