False, that is one thing many people were always doing, back then.

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.
a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere
b) all organisms are descended from one or a few common ancestors
c) the genetic code readily evolves by natural selection
d) there's only one possible way to encode information in a macromolecule
Answer:
b) all organisms are descended from one or a few common ancestors
Explanation:
Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.
Answer:
the answer should be ( 50% pink and 50% orange )
for better understanding u can make a cross yourself
if you want me to show that then I can put an attachment.
Four times as much genetic material is present in a cell during prophase I compared to a cell that has competed meiosis II. Prophase I is a phase in the first stage of meiosis (meiosis I). During this phase, chromosomes become visible. cross-over occurs, the nucleolus disappears, the meiotic spindle forms and the nuclear envelope disappears. The genetic materials in prophase I divides into two at the end of meiosis I forming tow daughter cells, which then divides again into two at the end of meiosis II forming four daughter cells.
