What is the linear sequence of amino acids as in DNA?
genetic code
| DNA triplet | RNA triplet | amino acid |
|---|---|---|
| AAG | UUC | phenylalanine |
| AAT | UUA | leucine |
| AAC | UUG | |
| GAA | CUU |
What is a stretch of DNA that codes for a specific protein called?
A linear stretch of DNA that codes for a specific protein is called a gene. This message is carried by messenger RNA (mRNA; ribonucleic acid) molecules, small single-stranded nucleic acids that contain the coding information of individual genes.
What do we call a segment of DNA that specifies the sequence of amino acids in a particular protein?
Gene. A segment of DNA that specifies the sequence amino acids in a polypeptide. Beadle and Tatum. Proposed that each gene specifies the synthesis of one enzyme.
What is a specific stretch of DNA that programs the amino acid sequence of a polypeptide?
A gene is a specific stretch of DNA that programs the amino acid sequence of a polypeptide.
What has a linear sequence of codons?
codons are arranged in a linear sequence along the DNA gene (and the mRNA transcript) with no gaps and no overlapping between words. the sequence of codons specifies the order and sequence of amino acids on the final polypeptide chain.
Why is genetic code linear?
The genetic code is written in linear form, using the ribonucleotides that compose mRNA molecules as letters. The ribonucleotide sequence is derived from the complementary nucleotide bases in the DNA template strand. Therefore, the nucleotide sequence is exactly the same as the DNA coding strand.
What are the stretches of DNA which carry information for protein synthesis known as?
To Gene. A gene is a stretch of DNA that contains the instructions for making or regulating a specific protein. Genes that make proteins are called protein-coding genes. In order to make a protein, a molecule closely related to DNA called ribonucleic acid (RNA) first copies the code within DNA.
What is the definition of exons?
Listen to pronunciation. (EK-son) The sequence of DNA present in mature messenger RNA, some of which encodes the amino acids of a protein. Most genes have multiple exons with introns between them.
What is a segment of DNA that specifies a sequence of amino acids?
cell: RNA: replicated from DNA each nucleotide triplet (called a codon) specifies a particular amino acid. Thus, a nucleotide sequence……
What is the term for a section of a DNA molecule that codes for proteins quizlet?
A gene is a section of a DNA molecule that contains the information to code for one specific protein. The gene contains the code that determines the structure of a protein.
How are fats phospholipids and steroids alike?
How are fats, phospholipids, and steroids alike? They are all solid at room temperature. They each contain a polar phosphate group. They each contain only 1 fatty acid.
