No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
Humans have 23 chromosomes in each cell
Each human chromosome is typically replicated in multiple sections called replication origins. These origins are sites along the chromosome where the DNA double helix unwinds and new DNA strands are synthesized during DNA replication.
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
23 - 22 autosomes + either an X or Y chromosome.
46.
A normal human being has 23 chromosomes from each parent, giving them 23 pairs or 46 in total.
The number of genes varies. Most of any chromosome consists of non-coding DNA, which does not contain any genes. Each chromosome has many chromatins. One gene consists of many chromatins. Therefore, one chromosome could have many genes.
Human cells typically have 46 chromosomes, which are organized into 23 pairs. Each chromosome in a pair contains identical components called sister chromatids, which are joined together at a region called the centromere.
