The vascular cambium produces secondary phloem and xylem tissue.
Vascular cambium, a plant tissue located between the xylem and the phloem in the stem of a vascular plant. It is also the source of both secondary xylem growth and the secondary phloem growth. Vascular cambium is usually found on dicots and gymnosperms not on monocots which usually lack secondary growth. It does not transport water, dissolved food or minerals by plants.Vascular cambia are cylinders of unspecialized meristem cells which divide to make new cells which specialize to form secondary vascular tissues.<span> </span>
<u>Answer:</u>
<em>B) it requires only transfer RNA (tRNA) and ribosomes.</em>
<u>Explanation:</u>
After the <em>transcription of DNA to RNA</em> in nucleus of cell, the ribosomes synthesis protein and this process is known as the Translation. <em>For the translation process to occur, it requires transfer RNA (tRNA) and ribosomes.</em>
The translation process is also known as cell expression. The ribosomes help in translation by inducing <em>transfer of tRNA sequence of anticodon to codon of mRNA.</em>
There are many forms of VIF and each forms are made for different purposes. basically, you just extract a female egg and a sample of the male sperm, bad sperm can be separated via by adding specific chemicals. The sperm will then be transferred into the egg and the egg is transferred into the women. (This is ICSI) There are other forms under the category of IVF but this is one of the example. (ICSI only deals with male infertility)
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
- Transcription
- Translation
During transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.
