Two sister chromatids are held together by the centromere

<h3>The Chromosome</h3>

The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.

Each of the sister chromatids carries an allele of the same gene.

The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Which best describes a gene
motikmotik

Answer;

a segment of chromosomal DNA

Explanation;

A gene is a  hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.

It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.  However, many genes do not code for proteins.

Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Hello, if any one knows how to fill in a punnet square please help meeeeee
omeli [17]
You can fill the sides with any allele.
After that the first box will be the dominant allele than the recessive allele, the box below that will be the dominant allele and the recessive allele. Dom being capitol and recessive being lowercase, the box on the top right will be dominant allele and recessive and bottom dominant and recessive. It’s all based on the allele of that row and column.
