Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
Answer:
As this is DNA replication, this is the unwinding process
Explanation:
In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-annealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwinding. An example is the gyrase.
The correct complementary RNA strand would be answer B!
Answer:
Classification change over time based on newly gathered information on species in order to accommodate them, such as molecular information about a species.
I don't know if this question is missing some multiple choice options that go along with it, but...
One plate will subduct (go under the other plate), creating a trench or subduction zone. The other plate goes over the subducted plate, creating raised ground. This is how mountains and volcanoes are made.
