Which amino acids have side chains that fit into the specificity pocket of chymotrypsin?
Answer:
The aromatic amino acids; Phenylalanine, Tryptophan, Tyrosine
Amino acids with bulky side chains; Leucine and Methionine
Explanation:
Chymotrypsin is a member of the serine proteases, which is family of enzymes that hydrolyze peptide bonds through the action of an active site serine.
Chymotrypsin cleaves peptide bonds on the C-terminal of aromatic amino acids or amino acids with bulky hydrophobic sides chains such as phenylalanine, tyrosine and tryptophan, leucine and methionine. This specificity for aromatic amino acids is due to its large hydrophobic pocket and due to the complementary nature of these amino acids when they bind to the pocket.

On topographic maps, how do you represent a steep slope?
A. Contour lines that are closely spaced
B. Contour lines that are dashed or dotted
C. A lack of contour lines
D. Contour lines that are far apart
Answer:
Contour lines that are closely spaced(Apex Approve)
Explanation:
On a topographic map the amount of elevation change is related to the number of contour lines. Using the same contour interval, the more contour lines over the same distance indicates a steeper slope. As a result, areas of a map where the contour lines are close together indicate steeper slopes

Crossing over shuffles alleles on:_____.a. sister chromatids.b. different non-homologous chromosomes.c. chromosomes within different cells.d. different homologous chromosomes.d. none of the answers are correct.
Answer:
d
Explanation:
Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.

Anytime you speculate about a problem and think of an answer based on what you
see on TV or read on the Internet, you are forming a scientific theory.
a. True
b. False
Answer:
b. False
Explanation:
A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.

Explanation:
From the test cross and X² test, I assume the individual is dihybrid and genes are in separate chromosomes. 1)25 aB. 2)X²=2. 3)P₀.₀₅=7.81. 4)Accept the model.
What is a test cross?A test cross is a cross we use to determine the genotype of individuals whose phenotype we already recognize.
The cross occurs between the individual of an unknown genotype and a recessive h0m0zygous individual. We want to know if the unknown genotype is heter0zyg0us or h0m0zyg0us dominant for a single gene.
Considering only one gene involved in the cross,
if the individual is heter0zyg0us, the progeny will be 50% heter0zyg0te and 50% h0m0zyg0te expressing the recessive trait.The phenotypic and genotypic ratio is 1:1
if the individual is h0m0zyg0us dominant, the whole progeny will be heter0zyg0us.Considering two genes that assort independently are test crossed,
If the individual is a dihybrid -heter0zyg0us for both genes-, the progeny will express equal phenotypic and genotypic ratio, 1:1:1:1.If more than one gene are involved, we can also determine if these genes assort independently, or if they are linked.
If genes are located in different chromosomes or are far from each other in the same chromosome, they assort independently, and their phenotypic and genotypic ratios are 1:1:1:1If these genes are linked, after the test cross, the distribution of phenotypes among the progeny differs from 1:1:1:1.When phenotypes appear in different proportions than the expected ones, we can assume that these genes are linked.
However, the difference between the observed and the expected data can be by random chance. This means that genes could assort independently, but by chance, the observed ratios vary from the expected ones.
To analyze these situations and determine is the difference is by chance or because genes are linked, we need to perform a chi-square test.
---------------------
Now, let us answer the question.
Available data:
Test cross
F1 = 100 individuals
AB 22 Ab 28 aB 29 ab 211) What expected number would you use for the aB class?
To answer this question, we assume genes assort independently, so if this is the case, genotypic ratio should be 1:1:1:1, or 25% AB : 25% aB : 25% Ab : 25% ab
100% ------------- 100 individuals
25% -------------X = (25% x 100) / 100% = 25 individuals AB
25% -------------X = (25% x 100) / 100% = 25 individuals aB
25% -------------X = (25% x 100) / 100% = 25 individuals Ab
25% -------------X = (25% x 100) / 100% = 25 individuals ab
So, accordig to our calculations, the expected number for the aB class is 25 individuals.
----------------------------
2) Calculate the chi-square value.
Model: dihybrid test cross of two genes on separate chromosomes -assort independently-.
AB Ab aB ab
Observed, O 22 28 29 21
Expected, E 25 25 25 25
(O-E)² / E 0.36 0.36 0.64 0.64
X² = Σ(Obs-Exp)²/Exp = 0.36 + 0.36 + 0.64 + 0.64 = 2
X² = 2
The chi-square value is X² = 2
-------------------------
3) Determine the probability that the model would give the observed data.
Freedom degrees = n - 1 Where n is the number of classes ⇒ 4.
Freedom degrees = 4 - 1 = 3
Significance level = 0.05
Conventionally, we use 0.05 = 5% as the significance level.
Critical value (table value) = 7.81
Considering a significance level of 0.05 and 3 freedom degrees, the critical value equals 7.81.
--------------------------
4) would you accept or reject your model?
X² = 2P₀.₀₅ = 7.81X² < P₀.₀₅ ⇒ 2 < 7.81
p value is greater than X², so there is not enough evidence to reject the null hypothesis. The ungenotype might be a dihybrid, and there might be independent assortment.
I would accept the model.
