Since the sequence of bases carries the instructions for making proteins and also regulates gene functions, the ability to read genetic sequences is enormously valuable to biological research. Because differences in DNA and RNA sequences can distinguish organisms down to species ...
What biological macromolecule provides the initial instructions for the primary sequence of proteins? A. mRNA B. tRNA C. rRNA D. DNA Proteins and Protein Synthesis Proteins are biologically important polymeric macromolecules that are formed from amino ac...
Deoxyribonucleic acid (DNA) is an organic molecule found in the nucleus of cells. It contains the genetic instructions for all living organisms. DNA is the molecule that encodes genetic information in cells and is made up of adenine, cytosine, thymine, and guanine. DNA molecules are highly stab...
What is the role of tRNA in the cell? a. transfers code from the DNA to proteins. b. forms part of the structure of the large ribosomal subunit. c. provides the instructions for protein synthesis based on DNA sequence. d. works with mRNA to positi...
Cells are the fundamental building blocks of every living system, and all the instructions required to control cellular activities are encoded within the DNA molecules, the total amount of DNA in a single cell being called the genome. Thehuman genomeincludes approximately 3 billion nucleotide pairs ...
DNA is thus in some sense the ‘blueprint’ for morphogenesis. However, it takes more to build a car than just an engineer’s blueprint; similarly, it takes more to build a tiger than just a list of instructions for what proteins to make and where to put them. They have to be made...
parents. Physically speaking, DNA is a long string of paired chemical units (nucleotides) that come in four different types, and it carries information organized into units called genes. Genes typically provide instructions for making proteins, which give cells and organisms their functional ...

Each string of DNA carries a set of instructions called genes. The gene tells the cell how to make a specific protein. Proteins are used by the cell to perform certain functions, to grow, and to survive. These genes are also passed down to offspring. Hydrogen Bonds in DNA Hydrogen bonds...
Set up the Elutrap Electroelution System (Whatman) with 0.5 × TBE buffer, according to manufacturer instructions. Place the gel pieces in the elution chamber and elute DNA by running at 200–300 V for 2–3 h into the trap. 11. Stop the run, quickly switch the cathode and anode, run ...
