Here are the answers to your questions:
Question 23
The type of amino acid that is added to the growing polypeptide depends on the
b. codon on the mRNA and the anticodon on the tRNA to which the amino acid is attached.
Question 24 Match the following terms with the correct definition:
- central dogma: f. describes the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein
- gene expression: a. the process by which possession of a gene leads to the appearance in the phenotype of the corresponding character.
- peptide: g. a compound consisting of two or more amino acids linked in a chain, the carboxyl group of each acid being joined to the amino group of the next by a bond of the type -OC-NH-.
- protein: b. chain made of individual amino acids.
- ribosome: e. site of protein synthesis
- RNA: c. a nucleic acid present in all living cells that has a ribose sugar.
- transcription: h. the first of several steps of DNA-based gene expression in which a particular segment of DNA is copied into RNA
- translation: d. the process in which ribosomes in the cytoplasm or ER synthesize proteins
Question 25
What type of mutation occurred at mutation #2 and does it cause a frameshift?
c. insertion - yes
Question 26
Down's Syndrome is also called Trisomy 21 because affected people have three copies of chromosome 21. How is this possible?
d. In a mistake in meiosis, the fertilized egg has two copies of chromosome 21.
Question 27
What is recombinant DNA technology useful in producing?
d. insulin and growth hormones
Question 28
What was the initial factor that led to the development of herbicide-resistant weeds?
a. genetic engineering
Question 29
If an organism has two different alleles for a given trait (like attached and free earlobes), they are considered ____________, and in __________ traits we automatically know the genotype.
b. hybrid, dominant
Question 30
According to this Punnett Square, what percentage of the offspring will be female?
d. 50
Question 31 Match the genotype or description with the correct descriptive term:
- Hh: a. Heterozygous
- HH: d. Homozygous dominant
- hh: b. Homozygous recessive
- long fur: c. Phenotype
Question 32 In rabbits, black fur is dominant to white fur. As a rabbit breeder, you crossed a BB male with a Bb female, please complete the Punnett square for the possible genotypes of the offspring. Then complete, the percent chance for the phenotypes of the offspring.
- All offspring will be Bb (100% black fur)
- % Black: 100
- % White: 0
Question 33
What term describes this process occurring in Prophase I?
c. crossing over
Question 34
Mendel's Law of Dominance states with a cross between two organisms,
c. only the dominant trait will show in the offspring.
Question 35
If an organism has two different alleles for a given trait (like attached and free earlobes), they are considered ____________, and in __________ traits we automatically know the genotype.
d. heterozygous, recessive
Question 36
Based on the information in this table, which men could not be the father of the baby?
(Select ALL correct answers)
- Without the specific genotypes, it's not possible to accurately determine the answer.
Question 37
What is the chance that their offspring will be white from two roan cattle?
d. 25%
Question 38
Can Jesse be the baby daddy?
c. No, this is impossible
Question 39 The question appears to be incomplete. Please provide the context or question text.
Question 40 Select ALL characteristics and information that CAN be obtained from a karyotype?
- a. number of sex chromosomes
- b. location of centromeres
- d. number of autosomes
- e. biological gender
- f. number of chromosomes
(Note: c. single gene inherited disease cannot be directly obtained from a karyotype.)
