Answer:  The answer is the D. "Observation" is not a variable in an experiment.

Explanation: Research variables are factors that can be manipulated, measured or those that we try to explain through other variables. "Observation" is not a variable in an experiment, but it is the first step and fundamental part in the scientific method, in which the experiments are contained (experimentation stage). Observation is the information recorded during an experiment, obtained through the senses or through the registration of information on scientific instruments.

suter [353]

Answer: c. are spliced out of the message.

Explanation: Intron are non-coding portion of the DNA sequence. They do not code for any specific amino acid and are spliced or removed before splicing.

Exons are DNA sequence that code for specific amino acid they are usually left after introns are removed and are joined together before translation into amino acid sequence. Intron splicing can lead to splicing some exons which can lead to formation of an entirely new amino acid or protein.

Spliceosome are enzymes for splicing introns.

Describe the genetic code and its relationship to polypeptides and proteins
konstantin123 [22]

The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.

What is the genetic code?

Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.

The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.

The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).
