Homologues separate to opposite ends of the cell. Sister chromatids stay together. Telophase I: Newly forming cells are haploid, n = 2.
Xylem is a very useful tissue in plants used for transportation of water from roots of a plant to its upper part for its proper growth
Answer:
A. Cartilage
Explanation:
The flexible tissue found in the nasal septum and in the ears is called cartilage .
Cartilage is one of the human body's many connective tissues, and is found between vertebrae, in joints between bones, in the rib cage, in the nose and ear, and in the bronchial tubes.
Cartilage is dense and non-vascular.
Answer:
Produce multiple polypeptide sequences from a single primary transcript.
Explanation:
Some genes produce more than one type of protein since the primary transcript encoded by these genes undergoes alternative splicing. These genes mostly have one segment that can serve either as intron or exon. Also called differential splicing, alternative splicing removes the segment as intron but retains it as an exon.
Splicing of the single primary transcript in different ways produces more than one version of mRNA from a single primary transcript encoded by a single gene. The alternative splicing allows the cells to produce multiple types of troponin proteins from single genes. These different troponin regulation muscle contraction in different muscles
