Answer: The Parietal lobe
:
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:
Chitinous exoskeleton and segmented bodies.
Explanation:
Phylum Arthropoda are known as jointed legs species which include crabs, spiders, ants, etc. The important characteristic of Arthropoda is they have a hard chitinous exoskeleton that provides them protection and gives flexibility. These phylum species can survive in both terrestrial and marine habitats. Some characteristics of phylum Arthropoda are given below:
1) They have Chitinous exoskeleton which is hardened.
2) Their digestive tract is present at opposite ends of the body and complete with the mouth and anus.
3) They contain jointed limbs.
4) The body structure of these species is showing bilateral symmetry.
A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a <u>dimeric</u> protein.
- Isozyme is a multimeric forms of enzyme having similar specificity of the substrate but differences in kinetics and molecular weights of the enzymes.
- The banding patterns of isozyme observed from electrophoresis is related to the genetic conditions in which different combination of polypeptide chains exhibited under the mendelian principles.
- Hence with the intensity of 1:2:1 ratio, three banded phenotypes are formed having two homomeric and one heteromeric form from the dimeric protein in both multiple alleles at single loci and multiple /single allele at multiple loci.
