During meiosis I, ____________ chromosomes line up side by side and may shuffle genetic material between themselves.
lozanna [386]

During meiosis I, homologous chromosomes line up side by side and may shuffle genetic material between themselves.

<h3>What is Meiosis?</h3>
  • In sexually reproducing organisms, meiosis is a unique type of cell division of germ cells that results in the production of gametes, such as sperm or egg cells.
  • Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome.
  • Prophase I, Metaphase I, Anaphase I, and Telophase I are the four phases that make up Meiosis I.
  • It deactivates the sporophytic information while activating the genetic information for the production of sex cells.
  • By halving the same, it keeps the chromosomal count constant.
<h3>What is chromosome?</h3>
  • A chromosome is a lengthy DNA molecule that contains all or a portion of an organism's genetic code.
  • Histones, which serve as packing proteins for the majority of eukaryotic chromosomes, work with chaperone proteins to attach to and condense the DNA molecule in order to preserve the integrity of the molecule.

Describe the structures of proteins and nucleic acids, and then explain the relationship between these two molecules within a ce
barxatty [35]
<span>Proteins are large biological molecules consisting of one or more chains of amino acids.  Proteins differ from one another primarily in their sequence of amino acids, which is decided by the nucleotide sequence of their make-up, and which usually results in folding of the protein into a three-dimensional structure that determines its job. 
    </span><span>Nucleic acids are linear polymers (chains) of nucleotides. Each nucleotide consists of three things: a purine , nitrogenous base a pentose sugar, and a phosphate group.  
    </span><span>
 Basically Proteins are chains of amino acids, nucleic acids are chains of nucleosides (base+sugar+phosphate), and the sequence of nucleic acid results in the specific sequence of amino acids in the protein, finnally determining its shape and function. </span>

A woman with an x-linked dominant disorder mates with a phenotypically normal male. on average, what percentage of this couple's
alex41 [277]
E. 0%

X-linked dominant disorders are not very common in females because it has to be on BOTH of their alleles in order to occur phenotypically.

Because you get one chromosome from your mom and another one from your dad, it would be impossible for the daughter to get the disorder because the dad doesn’t have it on his X chromosome to pass on to her.

In the case of the daughter, the focus is whether or not the dad has the disorder, the mom isn’t as relevant. However, if you were talking about a son, it would be a different story.

Hope this helps :)

What's a major assumption when drawing evolutionary relationships between organisms?
Xelga [282]

Based on DNA sequences, it is believed that changes in nucleotide sequence between two species are equivalent to the time that has elapsed since the two species diverged from their common ancestor. Gene sequencing is being used in addition to morphology to determine evolutionary relationships between organism. Homologous sequences show greater evolutionary relationship
