Question 1
A) What is the term for a section of a DNA molecule that codes for proteins?(1 point)
chromosome
cytosine
gene
deoxyribose
Question 2
A) Eukaryotic chromosomes tend to be much larger than prokaryotic chromosomes. In order to package these large chromosomes into the nucleus, which family of proteins are used by the cell?(1 point)
DNA polymerases
transcription factors
RNA polymerases
histones
Question 3
A) Which of the following choices correctly compares prokaryotic and eukaryotic chromosomes?(1 point)
Prokaryotic chromosomes are typically much larger than eukaryotic ones.
Prokaryotes tend to only have one chromosome while eukaryotes have many.
Prokaryotic chromosomes are wrapped into structures called nucleosomes.
.
Prokaryotic chromosomes are linear while eukaryotic chromosomes are circular.
Question 4
A) Which answer choice below correctly describes the structure of DNA?(1 point)
A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
Nitrogen bases on the outside with sugar-phosphate in the middle of a double helix.
Sugar-phosphate backbone with nitrogen bases coming off a single helix.
Sugar-nitrogen base backbone with phosphates in the middle forming a double helix.
Question 5
A) Chromosomes in eukaryotes are made of DNA wrapped around proteins. What is the combination of DNA and protein called?(1 point)
genes
histones
chromatin
nucleosomes
Question 1: Gene
Question 2: Histones
Question 3: Prokaryotes tend to only have one chromosome while eukaryotes have many.
Question 4: A sugar-phosphate backbone with nitrogen bases in the middle forming a double helix.
Question 5: Chromatin
I apologize for the confusion. The correct answer is nucleosomes.
Chromosomes in eukaryotes are made of DNA wrapped around proteins. What is the
combination of DNA and protein called? (1 point)
alleles
histones
nucleosomes
genes
that is not a answer
Question 1
The term for a section of a DNA molecule that codes for proteins is called a gene. To find this answer, you could refer to a biology textbook or search for the definition of "gene" in an online scientific database or website.
Question 2
In order to package large chromosomes into the nucleus, eukaryotic cells use a family of proteins called histones. To find this answer, you could search for information on how eukaryotic chromosomes are organized and packaged.
Question 3
The correct comparison between prokaryotic and eukaryotic chromosomes is that prokaryotes tend to have only one chromosome while eukaryotes have many. To find this answer, you could refer to a biology textbook or search for information comparing prokaryotic and eukaryotic chromosomes.
Question 4
The correct structure of DNA is described as a sugar-phosphate backbone with nitrogen bases in the middle forming a double helix. To find this answer, you could refer to a biology textbook or search for information on the structure of DNA.
Question 5
The combination of DNA and protein in chromosomes is called chromatin. To find this answer, you could refer to a biology textbook or search for information on the structure of chromosomes in eukaryotes.
