Answer:
Peas
Explanation:
Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.
Answer:
If we don't protect our forests, they get either get burned or cut down so that people can build more places or more space for crops. If we have little forest, there will be little oxygen in the air and we will die, global warming will also increase. Coral reefs are meant to protect the sea from inhumane acts which pollute the sea and cause marine animals to die, if they die the sea will be very polluted and marine animals might become extinct. Mangrove swamps are a habitat to many different animals, if they are gone the animals will have no habitat to live in and might soon face the consequences of extinction.
Answer:
B
Explanation:
nitrogenous bases on the two strands of DNA pair up, held together by weak hydrogen bonds.
Answer:
Because the leading strand is synthesized continuously while the lagging strand is discontinuously synthesized.
Explanation:
Two DNA strands have opposite polarity, that is, the 5' end of one strand lies opposite to the 3' end of the other strand. However, DNA replication can occur in 5' to 3' direction only since the formation of phosphodiester bonds require the presence of nucleophile 3' OH to attack the 5' phosphate of an incoming deoxyribonucleotide.
The problem is solved by the synthesis of the leading strand continuously and the synthesis of the lagging strand in a discontinuous manner. Lagging strand synthesis requires the formation of primers and their elongation to form Okazaki fragments that may have few hundreds to few thousands of nucleotides. Removal of primers from Okazaki fragments is followed by joining them together to make the long lagging strand. The discontinuous replication of the lagging strand makes the replication at the leading strand ahead of it.
