In terms of communication, information is expressed either as the content of a message or through direct or indirect observation. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.
Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a signal). It can also be encrypted for safe storage and communication.
Answer
Scientists studied the genomes of more than 1200 indigenous African living in the southern part of the continent today , they pieced together a history of one of the oldest DNA's . Which is passed down maternally through the mitochondria and has survived remarkably unchanged in some populations for hundreds of thousands of years.
Explanation:
Answer:
DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine)
Explanation:
Answer:
The correct answer is - lactase enzyme.
Explanation:
Crohn's disease may develop lactose intolerance as this disease causes inflammation in the bowel which affects the lining of the digestive tract. Lactaid is a commercial product that is helpful in the prevention of digestive problems when consuming dairy products.
Lactaid is nothing but an enzyme that helps in digestion or breaking down lactose sugar into galactose and glucose. Lactose sugar is present in the dairy products, that is not digested in the case of lactose intolerance.
Thus, the correct answer is - lactase.
Answer:
1, 5, 2, 3, 4
Explanation:
There are several enzymes involved in DNA replication and the step by step process of replication along with enzymes involved is as follows
a) Helicase is the first enzyme to act and it has a very important role in replication. Helicase unwinds the double helix of DNA
b) Single strands binding proteins prevent reattachment of DNA helix
c) Topoisomerase is responsible for relieving or inducing supercoils
d) The primase then lay the starting blocks made from RNA
e) DNA polymerase enzyme III lay the DNA from 5 prime to 3 prime.
f) DNA polymerase enzyme I then do half ladder replication
g) DNA Ligase links all the fragments.
Hence, the correct sequence is 1, 5, 2, 3, 4
