Yes, each human chromosome has a repetitive sequence at its ends called telomeres. These telomeres protect the chromosome from degradation and prevent it from fusing with neighboring chromosomes. As cells divide, telomeres shorten, which is associated with aging and limits the number of times a cell can divide. When telomeres become critically short, the cell may enter a state of senescence or undergo apoptosis.
What else can I help you with?
What is the name of the string of repetitive DNA at the tip of each chromosome in the body?
The repetitive DNA at the tip of each chromosome is called a telomere. Telomeres protect the chromosome from deterioration or fusion with neighboring chromosomes, and they shorten with each cell division. This shortening is linked to aging and disease.
What main goal of the human genome project is to?
It was meant toidentify all the approximately 20,000-25,000 genes in human DNA,determine the sequences of the 3 billion chemical base pairs that make up human DNA
Do human cells have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
How many chromosome 7 s are there in the human nucleus?
Two, one from each parent. Over 90,000 genes are found on each chromosome and are mostly responsible for protein productions.
Do humans have 46 genes?
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.

What is a complete list of nucleotide sequence in a individuals chromosome?
It is not possible to provide a complete list of nucleotide sequences on an individual's chromosome in a single answer, as each chromosome contains millions of nucleotides. The human genome has over 3 billion base pairs, which make up the DNA on 23 pairs of chromosomes. The sequence can vary between individuals due to genetic variations.
What is each one?
Each chromosome has genes on it in the form of coded base nucleotide sequence which is part of DNA.

How many of each chromosome does a human have?
1 billion
Do human cells have 46 genes?
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.
How many sections is each human chromosome replicated?
23
Each human chromosome is replicated in about how many sections?
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.
A cell with one of each kind of chromosome is what?
If you mean haploid, as in half of each chromosome, or containing only one chromatid from each full chromosome, thenthe cell is called haploid.
Each protein in an organism's DNA is coded for an individual?
Yes, each protein in an organism is coded by a specific sequence of nucleotides in its DNA. The genetic code determines how these sequences are translated into amino acids, which are the building blocks of proteins. Each protein has a unique sequence of amino acids that gives it specific functions within the organism.
Mapping all the genes on the human chromosome is called what?
This is the Human Genome Project. It was started in 1990 with the main goal being to determine the sequence of the base pairs which make up DNA, and to identify and map the thousands of genes of the human genome. It was completed in 2003. About 8% of the total genome remains unsequenced, because they did not study the entire DNA found in human cells.
