dominant trait would be expressed, but they'd be carriers for the
recessive trait.

Answer:
23 Chromsomes
Explanation
Thus, if a skin cell or somatic cell contains 46 chromosomes then the egg or sperm (gametes) would contain only 23 chromosomes
Answer:
<h2>1. toward</h2><h2>2. DNA ligase</h2>
Explanation:
- DNA replication is a process in which the synthesis of the new strand takes place from parental DNA or strand.
- DNA polymerase is an important enzyme that is responsible for the adding of the nucleotide and thus forms a new strand.
- During the process of synthesis one strand is synthesized in continuous forms that goes toward the replication fork and called as a leading strand that moves in 3' to 5' direction.
- The other strand that is synthesized in pieces form that is known as lagging strand and the pieces of the DNA is joined by an important enzyme known as DNA ligase.
D - the theory of natural selection states that the population will be narrowed as "less fit" organisms die and "more fit" organisms survive, passing on their beneficial genes to offspring. Therefore, more organisms are born than can survive.
When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
