Answer:
In asexual reproduction there is no mating or mixing of genetics. Asexual reproduction results in a clone of the parent, meaning the offspring have identical DNA as the parent.
One way for an asexually reproducing species to get diversity is through mutations at the DNA level. If there is a mistake in mitosis, the copying of the DNA, then that mistake will be passed down to the offspring, possibly changing its traits. Some mutations do not change the phenotype—or observable characteristics—however, so not all mutations in asexual reproduction result in variations in the offspring.
Explanation:
Answer:
A. FALSE
B. TRUE
C. FALSE
D. FALSE
Explanation:
A. DNA molecules consist of two strands of a helical chain of nucleotides, which are the monomer subunits of DNA.
B. Nucleotide subunits that make up a DNA strand are polar due to the presence of the phosphate group per subunit.
C. There are only four different nucleotides in a DNA strand. The nucleotides are different from each other based on the four nitrogen bases. These are adenine, thymine, cytosine, and guanine.
D. Hydrogen bonds are present between the nitrogen bases of nucleotides from anti-parallel DNA strands. Phosphodiester bonds, on the other hand are present between nucleotides of an individual DNA strand thus holding one DNA molecule together.
Answer:
Recombinant DNA
Explanation:
Recombinant DNA (or rDNA) is made by combining DNA from two or more sources. In practice, the process often involves combining the DNA of different organisms.
