How are genes present in a chromosome.?

Answer 1

Genes are linearly arranged on chromosome.

A chromosome is a very long DNA molecule, tightly packed with histone proteins. The entire stretch of DNA is a double helix: there are two strands and each strand is written in four genetic letters A, T, G, and C.

These four letters form 64 three-letter words, each word is termed a codon. 61 codons depict 20 amino acids (i.e. more than one codon could be present for one amino acid) while three are nonsense. We know that genes code for proteins: a gene is a recipe of a particular protein.

On the chromosomal DNA, some segments contain protein recipes and such segments are called genes. One chromosome may contain many genes.

Genes are segments of DNA molecules found within chromosomes. Chromosomes are long, thread-like structures made of DNA and associated proteins. Genes are organized along the length of chromosomes, with each gene occupying a specific location called a locus. The arrangement of genes on a chromosome determines the genetic information passed from parents to offspring.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
