Answer:
Due to the large number of fossils being discovered at that time Darwin proposed that species change over long periods of time.
Explanation:
The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive.
<span>This barrier is known as reproductive isolation and and generally occurs when two species have incompatible genitalia which are unable to function together. It can also occur when the sperm of the male species is unable to be fertilized by the female, regardless of genital compatibility.</span>
The average gene in the human genome is approximately <u>27,000 base pairs</u> base pairs in length.
<h3>What does human nuclear genome contain?</h3>
- One gene. The trypsinogen protein, an inactive precursor to the digestive enzyme trypsin, is synthesized using information from the TRY4 gene.
- Two parts of a gene: These two genes, designated V28 and V29-1, each code for a particular region of the T-cell receptor protein, for which the locus is called.
- Pseudogene one. A pseudogene is a replica of a gene that is not functional and often one whose nucleotide sequence has altered, rendering its biological information unintelligible.
- These are sequences that appear often across the genome.
- The terms LINEs (long interspersed nuclear elements), SINEs (short interspersed nuclear elements), LTR (long terminal repeat) elements, and DNA transposons refer to the four main categories of genome-wide repeats.
- Two microsatellites—sequences in which a brief motif is repeated twice—are involved. The sequence: is found in one of the microsatellites that has the pattern GA repeated 16 times.
5′- GGGGGGGGGGGGGGGGGGGGGGGG
3′-CTCTCTCTCTCTCTCTCTCTCTCTCTCTCTCT-5′
- The TATT sequence is repeated six times on the second microsatellite.
- Last but not least, almost 50% of the 50 kb portion of the human genome that we are interested in is made up of lengths of non-genic, non-repetitive, single-copy DNA that have no known meaning or function.
