What does the determination of sex (in humans) have to do with meiosis?
Allisa [31]

Answer:

In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY).

Coniferous forests evolved due to Earth’s continents assuming their modern configuration. true or false
Schach [20]

Answer:

True.

Explanation:

Coniferous forest may be defined as the the forest that are generally found in the area with cool winters and warm summers. The forest is the home of the broad leaves tress and needle like leaves.

The evolution of the coniferous forest occur due to the Earth’s continents. By assuming the modern configuration of the continent, the coniferous forest has evolved in the area that has the cool environment in the winter seasons and later leaves evolves according to the external environment.

Thus, the answer is true.

Answer/ Explanation:

The original DNA sequence has a point mutation changing a G to a T. The resulting mRNA produced is always complementary to the DNA from which it is synthesised, so the original mRNA sequence has a T, whereas the mutated mRNA has a U. The tRNA is complementary to the mRNA, so the original has a G, and the mutated has a T.

This is a point mutation called a substitution. This does not affect the entire sequence of the protein, because the mutation is "in frame" meaning the mRNA sequence is still read in the same way by the protein producing machinery. However, it does change the 5th codon from UGC to UGU. If we look up the genetic code, we can see that both of these codons code for cysteine, so there will be no change in the amino acid sequence of the protein
