Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
Because it takes LOADS of feathers to make up 1kg and lead would be such a small amount, it could fit in a purse.
We suppose the black fur is A and the white fur is a. The capital letter represents the dominant. Then the heterozygous black male is Aa and homozygous white female is aa. Then the offspring has two types, Aa and aa. The possibility of these two is equal and both are 50%.
Frogs have only one opening, called the cloaca, through which both feces and urine pass. Humans, however, possess two separate orifices for urine and feces to exit through.
Answer: fat
Explanation:
Carbohydrates, fats and proteins are among the major nutrients in the food component.
- Where proteins helps in growth of the body where as carbohydrates and fat provide energy. Protein has 4 calories per gram.
- Carbohydrates are instant form of energy. All carbohydrates turn into glucose and raise our blood sugar. Carbohydrate has 4 calories per gram.
- While fats are the slowest source of energy but provides most energy. Each gram of fat provides about 9 calories [ approximately more than twice that in proteins or carbohydrates].
Hence, fat gives you the most energy .
