BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...

which of the following components of an amino acid differs from one amino acid to another - Answerthe R group Sometimes atoms gain or lose particles. The loss of which of the following would result in a change of overall electrical charge? - Answer-protons or electrons what is the cell theory - Answer-1. theof cells A pair of shared valence electrons is referred to as a(n) - Answer-covalent bond scientists wanted to track the movement of specific organic molecules in a cell by using radioac...

Describe the structure of a nucleotide. What is the difference in the structure between RNA and DNA? How are nucleotides connected in DNA? - pentose sugar phosphate group connected at the fifth carbon nitrogenous base connected at the first carbon OH at carbon 3 DNA has H at carbon 2 RNA has OH at carbon 2 Nucleotides are connected by a 3',5' phosphodiester linkage. This means that the 3 carbon of one nucleotide is connected to the phosphate on the 5 carbon of another nucleotide. Wh...

What is a nucleotide? - Nitrogen base + sugar (ribose or deoxyribose) and phosphate group HOW ARE THE NUCLIOTIDE CONNECTED VERTICALLY? - THROUGH PHOSPHODIESTER BONDS WHAT ARE THE COMPLEMENTARY BASE PAIRS - A-T G-C WHAT TYPE OF BOND DOES THE COMPLEMENTARY BASE PAIRS HAVE? - DOUBLE HYDROGEN BONDS What is the backbone of DNA? - sugar and phosphate What is the 3 prime end - where the phosphate group doesn't stick out (shorter) What is the 5 prime end? - when the phosphate group stick out Wh...

BIOLOGY AQA AS 74011 PAPER 1 [WELL VERIFIED] • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a new complementary strand is made during semi-conservative replication of human DNA. Describe how the complementary strand of HIV DNA is made. - ANS---- there are complementary nucleotides/bases pair - DNA polymerase used - Nucleotides join together (to form new strand)/phosphodiester bonds form; Contrast the structures of ...

DNA is negatively charged because a. the ribose sugars of DNA are positively charged b. the ribose sugars of DNA are negatively charged c. the nitrogenous bases are negatively charged d. the phosphate backbone of DNA is negatively charged e. DNA is not acidic : d. the phosphate backbone of DNA is negatively charged DNA replication is a. semi-conservative b. dispersive c. conservative d. error prone : a. semi-conservative Define DNA helicase : unwinds DNA; that is, breaks the hydrog...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...
