Each position of a codon can be occupied by one of four nucleotides. What is the minimum number of nucleotides per codon necessary to specify all 20 of the amino acids that are found in proteins
Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.

What is the correct pathway of anaerobic respiration in yeast?
Choose 1 answer:
A.) Glycolysis -> Krebs cycle —> oxidative phosphorylation
B.) Glycolysis -> alcohol fermentation
C.) Glycolysis -> Krebs cycle -> fermentation
D.) Glycolysis -> lactic acid
fermentation
Answer:
B.) Glycolysis -> alcohol fermentation
Explanation:
The correct pathway of anaerobic respiration in yeast is Glycolysis -> alcohol fermentation. Thus option B is correct.
what is alcohol fermentation ?Alcohol fermentation is a complex process where sugars like glucose, sucrose, and fructose are converted into ethanol, carbon dioxide, and other metabolic by-products, these products are mainly contribute to the sensorial properties and chemical composition of the fermented food.
It is also called as ethanol fermentation is processed by yeast or some other microorganisms, used to make ATP. Yeast functions in the presence of oxygen called as aerobic fermentation but it can also perform in absence of oxygen or under anaerobic conditions.
This process show has a profound importance for the manufacturing of alcoholic beverages like beer and wine.

Chromatids are distributed to the 2 daughter nuclei Group of answer choices
M
G2
S
G1
Answer:
M
Explanation:
Mitosis is a type of cell division that involves the production of two daughter cells that are genetically identical to one another. Mitosis encompasses two stages namely: Interphase and Mitotic phase. The interphase which further consists of G1, S, and G2 phases, is a preparatory phase for the cell to grow and replicate its DNA.
However, the separation of the sister chromatids (replicated chromosomes) into two daughter nuclei occurs in the Mitotic or M phase. Note that the M phase comprises of stages that includes: prophase, metaphase, anaphase and telophase.
Answer:
M phase
Explanation:
Starch contains two polymers of glucose, they are amylose and amylopectin. Amylose differs from amylopectin in that
Answer:
Amylose is a straight chain whereas amylopectin is a branched chain polymer.
Explanation:
Amylose differs from amylopectin because amylose is a straight chain while on the other hand, amylopectin is a branched chain polymer. Branched chain polymers refers to main chain with smaller chains as branches of main chain while straight chain polymer has only main chain and no branches of main chain. Starch comprise of about 10-20% amylose and 80-90% amylopectin. Starch is considered as the main storage of energy for green plants.

The sputum (fluid coughed up from the lungs) of many smokers contain cells with mutations in the genes for p53. The smoking-induced mutations appear to be an early signal showing that cancer of the lungs will follow. What is the likely relationship between early p53 mutation and the development of lung cancer
Answer:
The correct answer would be - mutations in the p53 would prevent abnormal cells from dying by apoptosis.
Explanation:
P53 or tumor protein 53 gene is the gene that produces a protein that controls DNA repair and apoptosis in the cell cycle if there is an error in the DNA or cells growing abnormally therefore known as tumor suppressor gene.
If there is a mutation in this gene will prevent it from performing its function of DNA repair or stimulating apoptosis and then p53 would prevent abnormal cells from dying by apoptosis.
Thus, the mutation in P53 would lead to the growth or development of lung cancer.

GOTCHU
Answer: Diagnosing cystic fibrosis is a multistep process, and should include a newborn screening, a sweat test, a genetic or carrier test, and a clinical evaluation at a CF Foundation-accredited care center. Although most people are diagnosed with CF by the age of 2, some are diagnosed as adults. Also cystic fibrosis carriers do not have CF and are generally asymptomatic, there is emerging research which is finding that some carriers may have very mild symptoms associated with the genetic mutation. These symptoms may be a very pale shadow of the more severe symptoms someone with CF has.

Which population is most likely to be in Hardy-Weinberg equilibrium?
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
a large population of prairie grasses that lives in an ecosystem that is frequently burned by wild fires
a medium-sized population of birds that lives on a chain of islands that have different food sources
a medium-sized population of bacteria that lives on crop plants that are frequently sprayed with pesticides
Answer:
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
Explanation:
This is because the Hardy-Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. So if the large population of ocean fish isn't being disturbed by the pollution (unpolluted) and they have an abundant source of food they should in Hardy-Weinberg equilibrium since no major changes are happening.
