Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
Explanation:
The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I, but not in meiosis the II. After pairing up of in the prophase I, homologous chromosomes are able to exchange some corresponding segments and a cross-over occurs. Thanks to the cross-over event, each chromosome will have a new combination of genes. Without this, parents will produce gametes with only two different gene combinations.
Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
The ribosome plays a significant part in protein amalgamation inside a cell. Its fundamental reason is to encourage the interpretation of hereditary data from courier RNA (mRNA) into proteins.

Proteins are imperative particles that perform different capacities within the cell, counting enzymatic responses, auxiliary back, cell signaling, and transportation of particles. The ribosome acts as a atomic machine that collects amino acids, the building pieces of proteins, into particular groupings managed by the mRNA format.
The ribosome comprises of two subunits, a huge subunit and a little subunit, each composed of proteins and ribosomal RNA (rRNA). The little subunit ties to the mRNA particle, whereas the huge subunit joins amino acids together to create a polypeptide chain.

Answer:
To make Protein of course!
Explanation:
Function of Ribosomes. Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum. ... Proteins are an essential part of all cells.

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
