What is the difference between a body-cell and a sex-cell mutation in terms of inheritance?

Answers

Answer 1

Answer:

Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)

Which best describes genetic mutations? Some inherited genetic mutations can be good for the offspring. Different genetic mutations cause few forms of cancer. Somatic mutations can be inherited from parents or acquired during life. Genetic mutations that cause diseases are always passed on to offspring.

Answers

Genetic mutations are the changes in the genetic code and composition of organisms.

Genetic mutation can occur due to many factors like insertion, deletion, inversion of chromosomes.

The correct answer is:

Option A. Some inherited genetic mutations can be good for the offspring.

Mutations can be advantageous, inert or dangerous based upon the location of the genes.

Some mutations like in the case of sicklecell anemia in some communities conferred them resistance towards malaria disease.

The mutation can be beneficial as it can raise the chance of survival of the offspring.

Therefore, some inherited geneticmutations can be good for the offspring.

It is a polysacharide

Answer:

Explanation:

Polysaccharides are sugars that contain more than one basic sugar unit. Monosaccharide, on the other hand, contain only one sugar molecule.

How is most DNA duplication is the body accomplished?

Answers

most DNA duplicate through a process called mitosis

DNA carries the information for making all of the cell's proteins.These proteins implement all of the functions of a living organism anddetermine the organism's characteristics. When the cell reproduces, ithas to pass all of this information on to the daughter cells.Before a cell can reproduce, it must first replicate,or make a copy of, its DNA. Where DNA replication occurs depends uponwhether the cells is a prokaryote or a eukaryote (see the RNA sidebar onthe previous page for more about the types of cells). DNA replicationoccurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.Regardless of where DNA replication occurs, the basic process is thesame.The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel)directions. The beauty of this structure is that it can unzip down themiddle and each side can serve as a pattern or template for the otherside (called semi-conservative replication). However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule.Let's look at the details:An enzyme called DNA gyrase makes a nick in the double helix and each side separatesAn enzyme called helicase unwinds the double-stranded DNASeveral small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separatedAn enzyme complex called DNA polymerase"walks" down the DNA strands and adds new nucleotides to each strand.The nucleotides pair with the complementary nucleotides on the existingstand (A with T, G with C).A subunit of the DNA polymerase proofreads the new DNAAn enzyme called DNA ligase seals up the fragments into one long continuous strandThe new copies automatically wind up again

Which group of chordates has a notochord and includes separate males and females? jawless fish cartilaginous fish bony fish lancelets

Answers

Lancelets is the group of chordates that has a notochord and includes separate males and females.

Lancelet exhibits the four basic characteristics of phylum Chordata. It has a dorsal nerve, a notochord, a post annul tail, and pharyngiall gill slit.

Jawless fish, cartilaginous fish, and bony fish have notochord when they were still young but it was replaced by a vertebral column as they mature.

Lancelets are included in the subphylum cephalochordata. Cephalochordates are gonochoristics. It means that the sexes are separate. Both sperm and eggs cells are released in the water where fertilization occurs.

B.
genetic variation causes antibiotic resistance

Antibiotics, in one way or another, come from bacteria and fungi themselves. These antibiotics are produced naturally by the bacteria and fungi to eliminate competition with other bacteria present. With such great discovery in this endeavor, many lives were saved. It was not long that bacteria found ways to be resistant to antibiotics. Bacteria that was found on frozen dead bodies are resistant to modern antibiotics. There are two currently known ways as to how bacteria builds resistance against antibiotics. One would be mutation. Due to continued exposed to the antibiotic, the bacteria would adapt to it and cause themselves to mutate to combat antibiotic. The second one would be the swapping of DNA or as what scientists call the horizontal gene transfer. This only applies though to some or few bacteria that already has this feature built-in to them.
