Chapter 1: Principles of Biochemistry
A genome is a fixed of - ANS-genes
A hydrogen bond can first-class be defined as a - ANS-susceptible noncovalent interplay.
A nucleotide consists of - ANS-nitrogenous base, five-membered sugar and phosphate
corporations
A requirement for a covalent bond to form among two atoms is that - ANS-there are unpaired
electrons on every atom.
A section of DNA containing 20 base pairs consists of 8 adenine residues. How many uracil
residues are gift? - ANS-zero
A unmarried nucleotide base substitution in a wild-type DNA is an example of - ANS-random
mutation
Amino acids are the building blocks for which biomolecule(s)? - ANS-proteins
Amino acids are the building blocks of proteins. There are 20 amino acids; how do those amino
acids differ from one another? - ANS-Section 1.2
Amino acids range from one another in the aspect chain attached to the central carbon.
An instance of experimental biochemistry is making an attempt an experiment and -
ANS-optimizing experimental design
An inherited disorder comes from the mutation of DNA in a __________ mobile. -
ANS-germ-line
ATP is an abbreviation for which energy foreign money molecule? - ANS-adenosine
triphosphate
Bioinformatics indicates that 98% of human DNA is equal to that of chimpanzees. If human
DNA contains three.2 billion nucleotides, how many nucleotides are special between the 2
species? - ANS-64 million
By convention, nucleic acid chains are written starting on the __________ stop. - ANS-five'
Cell signaling and cell membranes are examples of functions completed via which biomolecule?
- ANS-fatty acid
, Compare and comparison a transcriptome and a proteome. - ANS-Section 1.Three
Although both transcriptomes and proteomes are collections of genetic material, a collection
of DNA transcripts (RNA products) generated by way of DNA transcription is called a
transcriptome,
while a proteome is the gathering of proteins produced with the aid of mRNA translation.
Compare and evaluation as a minimum three distinctive characteristics of prokaryotic and
eukaryotic cells. - ANS-Section 1.2
Prokaryotes are often 1 μm in diameter, their cytoplasm consists of all the enzymes and
chromosomes, and that they have flagella and pili. Eukaryotic cells are 10 to one hundred μm in
diameter,
chromatin is contained inside the nucleus, and they have a cytoskeleton.
Compare and assessment the bases found in DNA and RNA. - ANS-Section 1.Three
DNA is composed of the deoxyribonucleotides (missing an hydroxyl institution on the 2′ function
of ribose) guanine, cytosine, adenine, and thymine. RNA consists of ribonucleotides
(containing an hydroxyl group on the two′ position of ribose) guanine, cytosine, adenine,
and uracil.
Cyclic pathways contain several metabolites that regenerate at some point of every flip of the
cycle.
Another way to describe a metabolite is that it capabilities as a - ANS-reactant or product.
Define the critical dogma of molecular biology. - ANS-Section 1.3
The central dogma of molecular biology describes how genetic records saved in DNA is
used to direct the organic techniques in cells.
Describe the difference between a deoxyribonucleotide and a ribonucleotide - ANS-Section 1.2
Deoxyribonucleotides are monomeric units of DNA and shortage a hydroxyl institution at the
carbon
on the two′ function, while a ribonucleotide does have a hydroxyl organization on the carbon on
the
on the 2′ role.
Describe the differences between the systems of pyrimidine and a purine. - ANS-Section 1.3
A pyrimidine is an fragrant molecule with nitrogen at positions 1 and 3 at the ring, along
with a carbonyl at role 4. Examples of pyrimidines are cytosine, thymine, and uracil. A
