What's the difference between mitosis and meiosis

Biology
1 answer:
SashulF [63]3 years ago

Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other.

Use the principle of original horizontality to identify the two rocks that are nearly the same age.
Digiron [165]

The correct answer is - C and D.

The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.

In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.

By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?​
Mama L [17]

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
