Around 100,000 years ago there was a second hominine species closely related to modern humans, Homo <span><span>neanderthalensis,</span><span> or commonly called the Neanderthal</span>.</span> Recent studies of neanderthal DNA have shown that there is 3-4% of their genes in modern humans outside of Africa, mostly from Europe, including the ones for adapting to the cold and vitamin D absorption.
Answer:
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
- Mitochondrial DNA haplotypes are specific regions of mitochondrial DNA that cluster with other mitochondrial sequences to show the phylogenetic origins of maternal lineages.
- Mitochondrial DNA haplotypes are associated with a range of phenotypes and disease.
- Mitochondrial DNA contains 37 genes, all of which are essential for normal mitochondrial function.
- Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
Answer:
Mammals
Birds
Explanation:
The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Different animals have bones that appear very similar in form or function and seem to be related.
Examples
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.
The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.
Answer:
mutated dna
Explanation:
there would be either be dna substitutions, deletions or insertions. substitution simply changes the letter. deletion gets rid of a letter. insertion adds another letter.
Answer:
What is DNA polymerase.
Explanation:
DNA polymerase enzyme is the enzyme That reads the code and synthesizes the appropriate nucleotide base pairs according to the matching nucleotide after DNA splits during the replication process.
It helps in making the DNA error-free by proofreading. DNA polymerase III which has 2 molecules that work on both the strand leading and lagging strand.
Have a beautiful day! Miss Hawaii
