You continue your analysis by crossing the forked and twist lines. Your results are as follows: A cross between pure lines of twisted and forked flowers. The F1 generation was twisted and forked at the same time. When these flowers were crossed with each other, twisted, forked, and both twisted and forked flowers were obtained. Which of the following statements best explains the outcome of this cross? A. The forked mutation and the twist mutation are codominant alleles of the same locus. B. The forked mutation is incompletely dominant to the twist mutation. C. The twist mutation is incompletely dominant to the forked mutation. D. The forked mutation is epistatic to the twist mutation. E. The twist mutation is epistatic to the forked mutation.

A. The forked mutation and the twist mutation are codominant alleles of the same locus.

Explanation:

The question involves a single gene that codes for shape of flowers. According to the question, the F1 offsprings, after crossing pure lines, were both twisted and forked at the same time. After self-crossing the F1 offsprings, a twisted, forked and both forked and twisted offsprings were produced.

This depicts a non-mendelian genetic inheritance called CODOMINANCE. This is a genetic scenario whereby the alleles are neither dominant nor recessive to one another, instead, they are both expressed simultaneously. Here, the alleles for fork shape and twisted shape were neither dominant nor recessive to one another, but were phenotypically expressed together in the heterozygous offspring. Hence, the forklined and twisted alleles are said to be CODOMINANT.

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
