<span>A
typical human karyotype has 23 types of chromosomes arranged from largest to
smallest. In males and females 22 of these chromosomes look exactly the same
and they are called autosomes. The 23rd pair of chromosomes is the sex
chromosome which differentiates males from females. Females have 2 copies of
the x chromosome. Males have a copy of both x and y chromosome to make the 23rd
pair. <span>
<span>Chromosomes can also have abnormalities that
result to different conditions and identifiable traits. A most common
chromosomal abnormality is the condition called Down Syndrome, where chromosome
21 has a third copy because of an abnormal cell division.</span></span></span>
A phospholipid is made of glycerol, two the fatty acid tails, and a phosphate-linked head group. More unsaturated fatty acids it means less tightly packed phospholipids its results to the greater membrane fluidity. Unsaturated fatty acids are naturally occurring, meaning that the remaining hydrogen is on the same side of the molecule and result in a bending of the hydrocarbon chain.
How does molecular genetics add to our understanding of genes is by simply studying
them.
Molecular genetics is scientific study of composition of genes.
This field is a subcategory of biology and heredity which is responsible for
unearthing and delving the anatomy and physiology of the genes. This field
helps us to understand and find evidence in the compounds, substances and
elements found and synthesized in our genes and what contains in our nucleic
acides –RNA and DNA –framework of our chromosomes. And also the origin and history of how genes came to be. These are codes and
like-signals that makes us who we are in a macro-perspective.
Solid. They're all stuck together and they cannot move anywhere, whereas liquids and gasses flow and bounce around as they please. Hope this helps!!
TCA ATG CGT IS THE ANSWER.
Hope it helps. please ask if want more info and if you liked, mark brainliest also it will give you points.
