Answer:
Homo sapiens
Explanation:
I am so sorry if I get it wrong
the answer would be D.Australia. It’s completely separated from other areas of land by oceans.
Answer: D.
Explanation:
Dizygotic twins are formed due to the fertilisation of two eggs by two sperms which get implanted in the uterus and develops two fetuses, that s why they have 50% of genes in common. whereas monozygotic twins form from a single fertilized egg that splits and so they have 100% of their genes in common.
Hence, the correct statement is D.
D is the answer because down's syndrome is a genetic disorder caused by the presence of a third copy of chromosome 21.
1 and 2- You can use any moldable material (marshmallow or gummies) and any color you want, you need a least 6 colors (one for desoxyribose, one for phosphate, and one for each base)
3- There are 3 main steps in DNA replication:
Initiation: The DNA polymerase will attach to the DNA. the two strands of DNA will be separated and a replication fork will be formed
elongation: The DNA polymerase will put the appropriate nucleotide in front of each nucleotide of the parental strand DNA (A with T and G with C) while the replication fork is advancing.
Termination: The DNA polymerase will be separated from the DNA and the replication fork will be closed.
4- The complementary sequence of <span>GCTAATTGCATCCGA is:
</span><span>GCTAATTGCATCCGA
</span><span>CGATTAACGTAGGCT
5- The DNA polymerase ensure that no mistakes will be done in DNA replication by its proofreading activity, it means that the enzyme will check twice if the right nucleotide were put.
6- The largest scale you use, the more accurate it will be. to be reasonable, try to make it approximately 6 feet in length.
