Answer:
A gene is a section of a double-stranded molecule known as DNA. This molecule is found within the nucleus of the cell, contained in threadlike structures called chromatin. The two strands form a double helix linked by a series of paired bases. The base adenine is always linked to thymine and the base cytosine is always linked to guanine.
Answer:
Answer is C. By changing the shape of protein.
Explanation:
The site where the substrate binds and the chemical reaction take place is known as the active site.
Note that , if there is changes in the pH, it can affect the active site of the amino acid residue which usually have acidic or basic properties that is important for catalysis, thereby making it hard for substrate to bind.
Biosphere is one of the layers surrounding the earths surface where life exists. It represents the ecological system intergrating living things and their interactions with the environment relating to the other layers (hydrosphere, atmospheres, geosphere and the lithosphere). Photoautotrophs are organisms that make their own food using sunlight in a process called photosynthesis. They are responsible for the food supply in the biosphere.
Answer: nucleus
Explanation: In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). An mRNA travels to the ribosome, which uses the information it contains to build a protein with a specific amino acid sequence.
