if you took away all the DNA that codes for genes, you'd still have maybe 70 percent of the DNA left over…That's the so-called “junk DNA,” though the word “junk” is used sort of tongue in cheek. The assumption is that, even if this DNA doesn't make up any of the genes...
在“基因与基因病”一节所引用的“What exactly is a gene”这一科普动画中,描述不够准确的有( )。A.A. A gene is a special stretch of DNA that codes for something.B.A. Genes make proteins.C.A. Each one of our cells contains 46 strands of DNA.D.A. Some genes
b) gene. c) codon of mRNA. d) anticodon of tRNA. Fill in the blank: Any three base sequence found on the mRNA that codes for a specific amino acid is called a. Fill in the blank: is the structure that "reads" the codons of the mRNA strand during translation. A portion of a...

They tested the chemical on more people and discovered that about 70% of people can taste PTC, and for the rest it is completely tasteless. Genetic scientists discovered a genetic component for PTC taste receptors, and in 2003 they found the exact gene that codes for the taste receptor on ...
It is believed that each cell in our body contains over 25,000 genes, all working together. These genes carry specific biological codes or information that determine what we inherit from our parents. Genesare also a small section of Deoxyribonucleic Acid (DNA), a chemical that has a genetic ...
A major breakthrough regarding the pathogenesis of the autosomal recessive condition came with the identification of the HFE gene located on the short arm of chromosome 6 which codes for a membrane protein which plays an important role in the regulation of iron absorption in the small intestine (...
However, a plasmid that codes for an sites, selection to reduce costs to the host is likely to addiction complex exerts a cost on the cell, which means provide additional benefits to the parasite through such a plasmid will have a lower fitness with respect to enhanced vertical transmission. ...
What is a sequence of mRNA that codes for an amino acid called? mRNA: mRNA, which stands for messenger RNA, is an important molecule in the process of protein synthesis. mRNA carries a copy of a gene from DNA and is used as a template for translation into a sequence of amino acid...
