The process of protein formation directed by mRNA is called What process produces mRNA? How are DNA and RNA involved in protein synthesis? What converts DNA into mRNA? What is the process of copying DNA called? What form of RNA carries instructions from the nucleus to the ribosome?
RNA (which is covered in other modules) is composed of ribonucleotides . Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note the 5′-carbon (at the top) and the ...
DNA Structure The DNA structure can be thought of as a twisted ladder. This structure is described as a double-helix, as illustrated in the figure above. It is a nucleic acid, and all nucleic acids are made up of nucleotides.The DNA molecule is composed of units callednucleotides,and each...
If you lined up all of the DNA containing all of your genes, it would measure six feet long, but it’s coiled, so tightly that it fits in just one cell nucleus. DNA is a double-stranded molecule composed of sugar, phosphate, and four different bases: adenine, thymine, cytosine, and ...
Transcribe a sequence of DNA to the complementary RNA sequence. What would the sequence of bases of the anticodons on the tRNA be? Fill in the blank: Any three base sequence found on the mRNA that codes for a specific amino acid...
Thus, a DNA molecule is like a ladder that twists like a corkscrew, with the sugar and phosphate acting as the side rails and the base pairs acting as the rungs. Where Do We Find DNA? DNA is an extremely long molecule, so long that if all the DNA in a human was uncoiled and plac...

the blood cells spin to the bottom to make a sediment, and the clear liquid on top is called plasma. The laboratory technicians will put the sediment under a microscope and will examine it and count how many red blood cells, white blood cells, and platelets are in the sediment per square...
In the double-strand form of DNA, the base groups are paired. What base is found paired (hydrogen bonded) with thymine? Nucleic Acids: The primary information-carrying molecule in a cell is a nucleic acid. It is a biomolecule that is composed of...
