The polymerase continues transcribing for hundreds of nucleotides. At a point about 10 to 35 nucleotides past this sequence, the pre-mRNA is cut from the enzyme.

Genetics - Genetics - DNA and the genetic code: A major landmark was attained in 1953 when American geneticist and biophysicist James D. Watson and British biophysicists Francis Crick and Maurice Wilkins devised a double helix model for DNA structure. A triplet of DNA bases codes for one amino acid. A protein is a chain of amino acids, folded into the correct shape. Proteins are strands of amino acids. Every protein is encoded somewhere in the DNA of some organism’s genome. The segment of DNA that codes for a protein is called a gene or more appropriately an Open Reading Frame (ORF). 30 seconds . It’s called the “coding sequence” of the gene that encodes that particular protein. DNA is a long polymer made from repeating units called nucleotides, each of which is usually symbolized by a single letter: either A, T, C, or G. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. Ribosomal RNA (rRNA)-Type of RNA that makes up the major part of ribosomes. base that has a single ring. This is the direct connection between your genes … The protein formed corresponds to a specific trait (such as hair color, eye color). The sequence of DNA that codes for a protein and thus determines a trait is a. answer choices . Teachers. The code is read in triplet sets of nucleotide bases, called codons, that designate specific amino acids. The codons are three digits that are composed of any combination of the four RNA bases. sequence of DNA that codes for a protein and thus determines a trait. Messenger RNA (mRNA)-RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell. gene. nucleotide. SURVEY . Students. Community Guidelines.

Amino acids are linked together to form proteins. Login/Register CHAT WITH US Call us on: +1 (646) 357-4530. phosphate group. base that has a double ring. We take the first 3 bases from the figure above as example, which are AUG.

The DNA codon is the same except there is T instead of U. nitrogenous base.

Looking at the table, there are 64 total codons and they each represent a particular amino acid or function for the purposes of protein synthesis. gene.

Thus, gene depicts a particular trait of an organism. Q. Sequence of DNA that codes for a protein and thus determines a trait. 0. The sequence of nucleotides in DNA genes determines the order of amino acids in a protein. Specifically, the polymerase transcribes a DNA sequence called the polyadenylation signal sequence that codes for a polyadenylation sequence (AAUAAA) in the pre-mRNA. About. A certain combination of 3 bases always gives the same amino acids, so we can put the translation into a table (see below). Gene - a segment of DNA that codes for a protein, which in turn codes for a trait (skin tone, eye color..etc), a gene is a stretch of DNA.Nucleotide - consists of a sugar, phosphate and a base. 9. The standard genetic code is traditionally represented as an RNA codon table because, when proteins are made in a cell by ribosomes, it is mRNA that directs protein synthesis.The mRNA sequence is determined by the sequence of genomic DNA.With the rise of computational biology and genomics, most genes are now discovered at the DNA level, so a DNA codon table is becoming increasingly useful.
