Answer:
The correct answer will be-
1. Chromosomes are made up of protein and nucleic acid.
2. Genes are located on chromosomes.
3. Chromosomes are found in the nucleus.
Explanation:
Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".
The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.
The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.
But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.
Thus, the selected options are the correct answer.
Answer:
The correct answer is: E) both B and C.
Explanation:
- Bacteria and Archaea forms two distinct and different Domains in the Taxonomic classification system.
- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.
A drosophila mutant that has legs instead of antennae in its head is caused by a mutation in the phenotype is most likely found in the homeotic genes. The homeotic genes are the one responsible in regulating or formation of the structures in animals. This is likely where the mutation is found, causing the drosophila have legs on its head.
