Answer:
With respect to genetic information, it is true that a gene is a section of DNA and is found on a chromosome in the cell's nucleus.
Explanation:
DNA contains all the genetic information that determines the morphological and functional characteristics of living beings.
The structure of DNA contains specific sequences of 4 nitrogenous bases, whose extension constitutes the coded genetic information. A chromosome is formed by a DNA molecule, and the<u> </u><u>genes</u><u> contained in the chromosome locus are sequences of nucleotides coming from fragments of that same DNA</u>.
All the genetic information —DNA, chromosomes and genes— is located in the cell nucleus.
this is correct answer oky
Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Both were powerful nations and they served as trading hubs in their respective regions during that time.
Answer:
4
Explanation:
If we have the expression, 3/3/4.
Then this is the same as 3 × 4/3
Which is the same as 12/3
Which is the same as 4
Hence the value of the expression 3/3/4 is 4
