Answer:
1. Maurice Wilkins
2. Rosalind Franklin
3. Linus Pauling
4. Erwin Chargaff
5. James Watson
6. Francis Crick
7. Rosalind Franklin
8.
Explanation:
1. Maurice Hugh Frederick Wilkins was a British scientist, both a molecular biologist and physicist. He made an outstanding contribution to the scientific discovery of the DNA structure. He is well known for his work in the 1940s at King's College in London, where he used optical spectroscopy to understudy the structure of the DNA.
2. Rosalind Elsie Franklin was an expert x-ray crystallographer and chemist, she contributed immensely to the understanding and discovery of the DNA structures as well as the molecular structure of coal, RNA and viruses.
3. Linus Carl Pauling was an American scientist who made a huge impact in the field of molecular biology, he played an important role in the molecular modelling of proteins and this helped in further understanding the DNA code.
4. Erwin Chargaff was an American scientist who formulated the Chargaff's rules and his experimentations helped to show that the ratio of adenine in a DNA molecule was equivalent to the ratio of thymine, as well of the ratio of guanine in a DNA molecule was equivalent to the ratio of cytosine.
5. James Watson and Francis Crick both worked in the Cavendish Laboratory to elucidate the 3- dimensional structure of the DNA.
6. Maurice Hugh Frederick Wilkins along with James Watson and Francis Crick won the Nobel Prize for Physiology in 1962 for their discovery of the molecular structure of the DNA.
7. Rosalind Elsie Franklin was an English scientist and x-crystallographer was famous for "photo 51", this helped to first prove that the DNA was a double helix structure.
8. Rosalind Elsie Franklin worked out mathematically what a helical defraction should look like in an x-ray defraction photo.
Answer:
Option B, Transcription that originates at the core promoter and +1 site
Explanation:
In basal transcription process a special class of transcription factors which are nothing but the protein that binds to specific sites on DNA (which are also known as promoter sites) with an objective of activating transcription of genetic information from DNA to RNA , specifically messenger RNA. The transcription initiation requires association at promoter site(or regions of DNA that are found in the upstream of the coding region of a gene) along with a σ sub unit
Hence, option B is correct
D. Deforestation
Deforestation is a big cause of mass extinction because it destroys so many habitats leaving hundreds of species without a home or food and it forces them to live in an environment where the
y aren't capable of surviving.
The basic building block of a protein is called an amino acid. There are 20 amino acids in the proteins you eat and in the proteins within your body, and they link together to form large protein molecules. The variety of ways they mix and match allows for the great diversity of proteins in nature. Understanding the structure of amino acids and how they relate to the proteins they create can help you appreciate how critical these nutrients are in your diet.
On top of each kidney lies Adrenal gland. It's part of endocrine system. It's responsible for producing hormones like adrenalin, also steroids like aldosterone and cortisol. So in this case answer to your question is Adrenal gldans lie on top of kidneys
