Answer:DNA is shown to be the genetic material in bacteria and some phages.
DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed
Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.
DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence
Explanation:
1. Lipds is another macro molecule with different subnits of fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.
2 The correlation of action and absorption spectra varies with different organisms DNA. e..g in viral cells there is a wide difference between the absorption and action spectra, that is no correlation, while some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.
Babies are made when the male and female go into sexual intercourse and when the male finally reaches its “peak” the sperm goes into the egg and fertilizes it. I hope this helps!!
Answer:
The correct answer is the last statement.
Explanation:
Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.
Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.
Answer: the brain scans showed that there were areas of damage in the brains of all but one of the Mexico City kids. The damage was caused by air pollution.
Both DNA and RNA are made up of threee basic parts: phosphate groups, sugars, and nitrogenous bases. The main difference between DNA and RNA is that the nitrogenous base thymine (in DNA) is replaced with uracil (in RNA). The other three bases remain the same, adenine, guanine and cytosine. In DNA, adenine always pairs with thymine, but in RNA, adenine pairs with uracil.
