Sequence of amino acids in a polypeptide chain of protein molecule coresponds to the sequence of nucleotides on mRNA for that pr
tamaranim1 [39]

Answer:

330

Explanation:

A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.

Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.

                                     993-stop codon =990

                                     990/3=330

So that's why 330 amino acid will be incorporated in the polypeptide chain.

Answer:

Type of liquid

Explanation:

Daniela wanted to figure out what type of liquid worked best for growing beans. She watered one with coca-cola, one with lemonade, and one with just water. After one week, she measured how high they had grown. What is the independent variable?

Answer: An independent variable is a variable that does not depend on any other variable (it is the input variable) while a dependent variable is a variable that depends on other variable (it is the output variable).

In this question the two variables are the height of the plant after a week and the type of liquid used. Since the height of the beans depend on the type of liquid, therefore the height of the beans is the dependent variable while the type of liquid is the independent variable.
