Transport Across Cell Membranes Notes

Here we’ll look at a single gene on one DNA sequence. In reality this could be thousands of base pairs long, but I will be simplifying the size of all these products throughout this video.

Each strand of DNA contains many genes. Transcription is making a copy of one of these genes that can then be used as the directions for the amino acid order in a protein.

Mitosis is the part of the cell cycle during which the cell divides, forming two genetically identical cells.

Meiosis is cell division in the gonads (the ovaries or testes) that results in genetically unique gametes (eggs or sperm) containing only ONE copy of each gene.

Carbon, hydrogen, oxygen, and nitrogen (CHON) are the most common elements in life forms. Carbon in particular is amazing in that it loves to form four bonds with other atoms. It and hydrogen are found

Nucleic acids are one of the four kinds of “biomolecules”. The other three are lipids, proteins, and carbohydrates. Each DNA strand contains the genetic information of one chromosome. Each chromosome contains 50 - 250 million nucleotide pairs.

Nucleic acids are one of the four kinds of “biomolecules” (because they are found in living things). The other three are lipids, proteins, and carbohydrates. You may also see them referred to as “organic molecules” (because they are based on carbon structures), or “macromolecules” (because they are so huge)

DNA replication produces two identical molecules of DNA from the original. This process occurs during S phase of interphase.
