Multiple Choice
In eukaryotic cells, how are DNA and chromosomes related?
A
Chromosomes are made of RNA and are translated into DNA during S phase.
B
DNA and chromosomes are unrelated structures; chromosomes consist only of proteins that regulate gene expression.
C
DNA is produced by chromosomes and stored in the cytoplasm until it is needed for transcription.
D
A chromosome is a single long DNA molecule packaged with histone and other proteins into chromatin.
Verified step by step guidance1
Step 1: Understand the basic components of chromosomes in eukaryotic cells. Chromosomes are structures found in the nucleus that carry genetic information.
Step 2: Recognize that chromosomes are primarily composed of DNA, which is a long molecule that contains the genetic code, and proteins, mainly histones, which help package and organize the DNA.
Step 3: Learn that the DNA in chromosomes is wrapped around histone proteins forming a complex called chromatin, which allows the long DNA molecules to be compacted to fit inside the nucleus.
Step 4: Clarify that chromosomes are not made of RNA, nor are they translated into DNA; rather, DNA is the fundamental molecule of chromosomes and serves as the template for RNA synthesis during transcription.
Step 5: Summarize that a chromosome is essentially a single, continuous DNA molecule tightly packaged with proteins, enabling efficient storage, regulation, and transmission of genetic information during cell division.
