Key processes facilitated by chromosomal sequences in their role at the molecular level include: Chromosome replication, chromosome compaction, proper segregation of chromosomes, RNA and cellular protein synthesis.
What is DNA sequence on the chromosome and can you sequence chromosomes?
- DNA sequencing means determining the order of the four chemical building blocks (called "bases") responsible for composition of the DNA molecule. This sequence tells scientists what genetic information is contained in a particular segment of DNA.
- The human chromosome has been completely sequenced for the first time, so why is this breakthrough important for the future of the reference genome? The two-end array was announced for the first time.
How many chromosomal sequences are there?
In animals (including humans) and plants, chromosomes are located inside the cell nucleus. Humans have 22 pairs of numbered chromosomes (autosomes) and 1 pair of sex chromosomes (XX or XY) for a total of 46.
