Question

Indirect evidence that DNA is the genetic material in eukaryotes: Genetic material should be in the nucleus ____ and ______ are present also in the cytoplasm and DNA is not. Only mitochondria, chloroplasts and maternal effect are genetic events that happen in the cytoplasm.

A) Ribosomes; Proteins
B) Ribosomes; RNA
C) Nucleolus; Ribosomes
D) Ribosomes; Mitochondria

Answer 1

The genetic material in eukaryotes is DNA, and there is indirect evidence to support this. Ribosomes in the cytoplasm use RNA to carry instructions from DNA for protein synthesis.

Step-by-step explanation:

The genetic material in eukaryotes, such as animals and plants, is DNA. However, there is indirect evidence that supports DNA as the genetic material. While DNA is found in the nucleus, other genetic events, such as protein synthesis, occur in the cytoplasm.

Ribosomes, which are responsible for protein synthesis, are present in both the nucleus and the cytoplasm. Proteins are made at ribosomes in the cytoplasm using the instructions carried by RNA, a type of nucleic acid. This suggests that RNA serves as an intermediary between DNA and protein synthesis outside the nucleus.
