# What methods are available today to sequence the genome of a living organism? ### What methods are available today to sequence the genome of a living organism?

The method de Sanger has enabled scientists to sequence the DNA of many organisms, ranging from bacteria to humans. Using fluorochromes and a computer, it is possible to sequence a person’s DNA (which comprises three billion bases) in the space of a few days.

### What is the definition of the square function?

1. Definition of the square function. We call function square the function f which associates its square x² to any number x. For any real x, we denote f(x) = x². Examples: The image of 4 by the square function is 16. The image of – 7 by the square function is 49. The image of by the square function is 7 . 2.

### What is Residual Error Sum of Squares?

The sum of the squares of the residual error is the variation attributed to the error. Comparing the sum of squares of the regression to the total sum of squares indicates the proportion of the total variation explained by the regression model (R 2 , coefficient of determination).

### What is the difference between a square and a sequence?

Each line of the square offers a new comparison with the sequence to be found. The information is precise and complete: “1 digit in the right place” means that there is only one and only one digit in the right place and that there are none in the wrong.

### What is the sum of squares?

The sum of squares is a measure of variation or deviation from the mean. It represents the sum of the squares of the differences from the mean. The calculation of the total sum of squares takes into account the differences due to the factors and those due to chance or error. Sums of squares in an ANOVA
