(b) What is a DNA fragment made of? DNA: Deoxyribonucleic acid (DNA) is a vital molecule because it stores and encodes all of the information necessary for life. It is essentially the genetic blueprint of life and carries in its sequences all of the instructions a...
What are the monomer 'building blocks' that make up the protein? (a) Monosaccharides (b) Glycerol molecules (c) Amino acid (d) Fatty acid (e) Cholesterol molecules What type of molecules have subunits called monosaccharides? What type of molecule is shown below: lipid, nucleic a...
a DNA molecule is cut into smaller pieces and then used as a template for a particular strand of RNA that has been copied from the DNA’s matching complementary strand. This RNA is then
cycle to generate energy. Each cycle of beta-oxidation removes two carbon atoms from the fatty acid chain and produces one molecule each of NADH and FADH2, which can be used for oxidative phosphorylation to produce ATP. Since fatty acid oxidation can occur multiple times, the energy yield is ...
DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytos...
The double-stranded DNA “melts” apart into single-stranded DNA, and this process is called DNA denaturation.Now, what is DNA renaturation? It’s the opposite process! DNA renaturation occurs when the two single strands of a once double-stranded DNA molecule reassociate with one another — ...
The analysis of cellular ultrastructure is paramount for gaining a comprehensive understanding of cell functionality. By examining the intricate details within a cell, researchers can uncover the mechanisms that drive various cellular processes and functions. ...
What is the basic unit of DNA called? Which molecule is not found in DNA? a. uracil b. guanine c. adenine d. deoxyribose e. phosphate Which base is used in RNA but not in DNA? Which base is used in RNA but not DNA? How many different kinds of bases can be found in the DNA?
(b) Describe the structure of bacteria.Virus:A virus is the smallest infectious agent which only replicates in a living host as plant, animal, and bacteria. Without a host cell, it cannot do its metabolic activities. They are made up of DNA and a protein coat ca...
