Why do a human and monkey look different?
the type of cells
the location of the DNA in a cell
the DNA sequence
the organization of cell structures
Answer (2)
The DNA sequence contains the genetic code that provides the instructions for building and operating an organism. Even though humans and monkeys share a significant portion of their DNA (around 93-98% depending on the monkey species), the small percentage of difference in the DNA sequence accounts for the vast array of physical and behavioral distinctions between the two species.These differences in DNA sequence lead to:Different protein structures and functions.Variations in gene expression (when and where genes are turned on or off).Differences in developmental pathways, leading to different body plans, limb proportions, brain size, hair distribution, facial features, and many other characteristics.
The DNA sequence refers to the specific order of nucleotides (A, T, C, and G) in a DNA molecule. This sequence is the genetic blueprint that determines an organism's traits. DNA sequencing is the process of determining this precise order.
