How can I remember the definition of lysogenic cycle? Read below for the definition. I need help memorizing it.

A. Lipid bilayer: the phospholipid bilayer is the membrane of a cell. The bilayer contains lipids, membrane proteins, cholesterol, receptors for various molecules, pumps to transport ions and solutes against the concentration gradient, and many other items necessary for a cell to function and work together with other cells.

b. Osmotic pressure: Osmosis is the flow of water across a semipermeable barrier from an area of low solute concentration to high solute concentration. Osmotic pressure is the lowest possible pressure to prevent this water movement.

c. Endoplasmic Reticulum: the Rough ER synthesizes proteins for use outside the cell. The Smooth ER produces lipids and some steroidal hormones.

A. Lipid Bilayer is therefore the correct answer. Osmotic pressure does not involve the various components of the cell membrane, and the ER's produce proteins and hormones. Therefore A is right.

Hope this helps! :) Let me know if you need a clarification.

Do bananas contain radiation?

Ne4ueva [31]

<span>You are right in that bananas contain potassium and K-40 is a naturally occurring potassium isotope AND the K-40 in an average banana does decay at a rate of about 31 ATOMS per second (half-life is > 1 billion years). This is an extremely low level of radiation and nothing to worry about. Bananas will definitely NOT cause a "nuclear winter."</span>

How does a mutation in the DNA affect the way proteins are made?

Vikentia [17]

Explanation:

B.) A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

somatic: these only occur within certain cells, and arise from environmental factors such as UV light
hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They exist solely to encode and carry out protein synthesis.

The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand in transcription. These are then translated into proteins in ribosomes. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

They are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.

<em>e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.</em>
