What is the primary product of light independent reactions
SOVA2 [1]

The primary products of the light independent reactions  (after one turn of the cycle) are:

a)  two G3P molecules

b)  three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions.  Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of  the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there  remains only one carbon for the next turn of the cycle.

One  molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.

A mistake in DNA replication, in which the wrong base is placed in the growing DNA strand, can have profound effects on the desc
Klio2033 [76]

Answer:

DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside  the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.

Explanation:

The original strand is: TAGCGTT

                                      ATCGCAA

The Mutated strand is: TGGCGTT

                                       ATCGCAA

<em>The replicated strand is: GAATCAC</em>

<em>                                           CTTAGTG</em>

IrinaK [193]

Answer:

birds

Explanation:

<em>Archaeopteryx</em> is an iconic fossil bird that lived during the Late Jurassic, approximately 150 million years ago. <em>Archaeopteryx</em> is iconic because it is a transitional fossil between non-avian dinosaurs (reptiles) and birds. The osteology of <em>Archaeopteryx</em> indicates that it was similar to that of nonavian theropod dinosaurs, i.e.,  dinosaurs characterized by hollow bones and three-toed limbs. Unlike modern birds, <em>Archaeopteryx</em> had a full set of teeth, a long tail, three fingers with claws and hyperextensible second toes commonly known as 'killing claws'.
