Predicting the genotype of offspring
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele. Both parents produce 25% each of AB, Ab, aB, and ab.
D. egg cell and sperm
basically gametes make babies and those are the two things you need to create one.
Answer: B. DNA polymerase checks for errors in base pairing as it helps new DNA strands form.
Explanation: DNA polymerase is an enzyme that catalyzes the synthesis of a new DNA strand from a DNA template. This process is known as replication. During replication, DNA polymerase rejects incorrect bases before the phosphodiester bond is formed because it has a 3' -> 5' exonuclease activity that double checks every nucleotide that is added to the growing strand. This check allows the enzyme to remove a newly added mismatched base pair.
1. Like living things, viruses have genetic material and 2. viruses can evolve.
- Viruses share many genes with their host cells. Viruses are dependent on living organisms, which lead to some living characteristics - they can reproduce/replicate in living host cells, mutate, appear in different strains, and have unique genetic material. However, viruses are classified as not living things because they can’t carry out the necessary processes that meet all requirements for the classification of a living thing. They do NOT undergo respiration and cannot generate energy needed to survive on its own, but viruses *do* share a few features with living things.
