TRUE/FALSE

Biology
1 answer:
kotykmax [81]4 years ago
5 0

Answer:

False

Explanation:

A double-helical DNA molecule consists of two DNA strands. A DNA strand has free 5' phosphate at one end and a free hydroxyl group (OH) at its 3' end. A DNA double helix is said to be antiparallel since each end of the double helix has an exposed 5' phosphate on one strand and a free 3' hydroxyl group (OH) on the other. This means that the two DNA strands run in opposite directions. A phosphate group is always esterified to the 5' carbon of the pentose sugar; never at its 3' end.

If the DNA content of a diploid cell in prophase I is x, what would it be for the same cell at prophase II?
pentagon [3]
<span>A is the correct answer. Diploid cells all contain two sets of chromosomes. Prophase 1 occurs during the first phase of meiosis, a type of cell division, and prophase 2 is the same process, but this time occurring without chromosome reduplication. As a result, there is the original and duplicated cells, which makes two.</span>

For two autosomal dominant genes, what is the probability that a cross between two heterozygotes (i.e. AaBb x AaBb) will produce
oksian1 [2.3K]

Answer:

1 in 16

Explanation:

When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.

Proteins that are embedded within, and extend across, the phospholipid bilayer are called _____ proteins. rev: 02_22_2014_qc_455
brilliants [131]

Proteins that are embedded within, and extend across, the phospholipid bilayer are called <u>Integral Protein</u>.

Integral Protein- Any protein containing a unique functional area for the purpose of ensuring its location within the cellular membrane is referred to as an integral protein, which is also referred to as an integral membrane protein. Or, to put it another way, an integral protein seizes the cellular membrane.

Cellular membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

#1. Which of the following structures would you expect to find in a single-celled organism? A. internal organs B. legs and feet
qwelly [4]
1. outer covering - none of the other answers can occur due to the absorbed solutions inability to reach the centre of the organism, smaller cells in greater numbers are more efficient as they can group together yet all absorb the right amounts of nutrients for its need. multi cellular organisms, such as humans can have the other answers in them as cells group together to make skin, muscles and organs. it also gives the organism to grow larger.

2. bacteria are single celled. bacteria reproduce through mitosis (cell division). bacteria break down decaying matter to obtain energy. every organism requires energy to live. Bacteria can move in order to reach their nutrient source.
