Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
Explanation:
Segmentation in biology is the division of some animal and plant body plans into a series of repetitive segments. This article focuses on the segmentation of animal body plans, specifically using the examples of the taxa Arthropoda, Chordata.
Answer:
conifers: Cones
Explanation:
Conifers have cones (hence their name). Cones are the reproductive structures ofthe conifers: Cones are diploid tissue produced by the dominant sporophyte stage. The haploid gametophyte stage develops and produces gametes inside the cone.
The answer is Ser-Arg-Ala-Val-Gly-STOP
It is known that three nucleotide bases on mRNA are called
codon and that each codon codes for the specific amino acid. According to the
genetic code chart, the following mRNA sequence will code for the following
amino acid sequence:
mRNA sequence: <span>UCU CGA GCC GUU GGG UGA</span>
Amino acid sequence: Ser Arg Ala Val Gly STOP
